text: Dynamic reorganization of the cytoplasm is key to many core cellular processes,
such as cell division, cell migration, and cell polarization. Cytoskeletal rearrangements
are thought to constitute the main drivers of cytoplasmic flows and reorganization.
In contrast, remarkably little is known about how dynamic changes in size and
shape of cell organelles affect cytoplasmic organization. Here, we show that within
the maturing zebrafish oocyte, the surface localization of exocytosis-competent
cortical granules (Cgs) upon germinal vesicle breakdown (GVBD) is achieved by
the combined activities of yolk granule (Yg) fusion and microtubule aster formation
and translocation. We find that Cgs are moved towards the oocyte surface through
radially outward cytoplasmic flows induced by Ygs fusing and compacting towards
the oocyte center in response to GVBD. We further show that vesicles decorated
with the small Rab GTPase Rab11, a master regulator of vesicular trafficking and
exocytosis, accumulate together with Cgs at the oocyte surface. This accumulation
is achieved by Rab11-positive vesicles being transported by acentrosomal microtubule
asters, the formation of which is induced by the release of CyclinB/Cdk1 upon
GVBD, and which display a net movement towards the oocyte surface by preferentially
binding to the oocyte actin cortex. We finally demonstrate that the decoration
of Cgs by Rab11 at the oocyte surface is needed for Cg exocytosis and subsequent
chorion elevation, a process central in egg activation. Collectively, these findings
unravel a yet unrecognized role of organelle fusion, functioning together with
cytoskeletal rearrangements, in orchestrating cytoplasmic organization during
oocyte maturation.

text: Understanding complex living systems, which are fundamentally constrained
by physical phenomena, requires combining experimental data with theoretical physical
and mathematical models. To develop such models, collaborations between experimental
cell biologists and theoreticians are increasingly important but these two groups
often face challenges achieving mutual understanding. To help navigate these challenges,
this Perspective discusses different modelling approaches, including bottom-up
hypothesis-driven and top-down data-driven models, and highlights their strengths
and applications. Using cell mechanics as an example, we explore the integration
of specific physical models with experimental data from the molecular, cellular
and tissue level up to multiscale input. We also emphasize the importance of constraining
model complexity and outline strategies for crosstalk between experimental design
and model development. Furthermore, we highlight how physical models can provide
conceptual insights and produce unifying and generalizable frameworks for biological
phenomena. Overall, this Perspective aims to promote fruitful collaborations that
advance our understanding of complex biological systems.

text: "The tight spatiotemporal coordination of signaling activity determining embryo\r\npatterning
and the physical processes driving embryo morphogenesis renders\r\nembryonic development
robust, such that key developmental processes can unfold\r\nrelatively normally
even outside of the full embryonic context. For instance, embryonic\r\nstem cell
cultures can recapitulate the hallmarks of gastrulation, i.e. break symmetry\r\nleading
to germ layer formation and morphogenesis, in a very reduced environment.\r\nThis
leads to questions on specific contributions of embryo-specific features, such
as\r\nthe presence of extraembryonic tissues, which are inherently involved in
gastrulation\r\nin the full embryonic context. To address this, we established
zebrafish embryonic\r\nexplants without the extraembryonic yolk cell, an important
player as a signaling\r\nsource and for morphogenesis during gastrulation, as
a model of ex vivo development.\r\nWe found that dorsal-marginal determinants
are required and sufficient in these\r\nexplants to form and pattern all three
germ layers. However, formation of tissues,\r\nwhich require the highest Nodal-signaling
levels, is variable, demonstrating a\r\ncontribution of extraembryonic tissues
for reaching peak Nodal signaling levels.\r\nBlastoderm explants also undergo
gastrulation-like axis elongation. We found that this\r\nelongation movement shows
hallmarks of oriented mesendoderm cell intercalations\r\ntypically associated
with dorsal tissues in the intact embryo. These are disrupted by\r\nuniform upregulation
of BMP signaling activity and concomitant explant ventralization,\r\nsuggesting
that tight spatial control of BMP signaling is a prerequisite for explant\r\nmorphogenesis.
This control is achieved by Nodal signaling, which is critical for\r\neffectively
downregulating BMP signaling in the mesendoderm, highlighting that Nodal\r\nsignaling
is not only directly required for mesendoderm cell fate specification and\r\nmorphogenesis,
but also by maintaining low levels of BMP signaling at the dorsal side.\r\nCollectively,
we provide insights into the capacity and organization of signaling and\r\nmorphogenetic
domains to recapitulate features of zebrafish gastrulation outside of\r\nthe full
embryonic context."

text: Embryo development requires biochemical signalling to generate patterns of
cell fates and active mechanical forces to drive tissue shape changes. However,
how these processes are coordinated, and how tissue patterning is preserved despite
the cellular flows occurring during morphogenesis, remains poorly understood.
Gastrulation is a crucial embryonic stage that involves both patterning and internalization
of the mesendoderm germ layer tissue. Here we show that, in zebrafish embryos,
a gradient in Nodal signalling orchestrates pattern-preserving internalization
movements by triggering a motility-driven unjamming transition. In addition to
its role as a morphogen determining embryo patterning, graded Nodal signalling
mechanically subdivides the mesendoderm into a small fraction of highly protrusive
leader cells, able to autonomously internalize via local unjamming, and less protrusive
followers, which need to be pulled inwards by the leaders. The Nodal gradient
further enforces a code of preferential adhesion coupling leaders to their immediate
followers, resulting in a collective and ordered mode of internalization that
preserves mesendoderm patterning. Integrating this dual mechanical role of Nodal
signalling into minimal active particle simulations quantitatively predicts both
physiological and experimentally perturbed internalization movements. This provides
a quantitative framework for how a morphogen-encoded unjamming transition can
bidirectionally couple tissue mechanics with patterning during complex three-dimensional
morphogenesis.

text: Ventral tail bending, which is transient but pronounced, is found in many
chordate embryos and constitutes an interesting model of how tissue interactions
control embryo shape. Here, we identify one key upstream regulator of ventral
tail bending in embryos of the ascidian Ciona. We show that during the early tailbud
stages, ventral epidermal cells exhibit a boat-shaped morphology (boat cell) with
a narrow apical surface where phosphorylated myosin light chain (pMLC) accumulates.
We further show that interfering with the function of the BMP ligand Admp led
to pMLC localizing to the basal instead of the apical side of ventral epidermal
cells and a reduced number of boat cells. Finally, we show that cutting ventral
epidermal midline cells at their apex using an ultraviolet laser relaxed ventral
tail bending. Based on these results, we propose a previously unreported function
for Admp in localizing pMLC to the apical side of ventral epidermal cells, which
causes the tail to bend ventrally by resisting antero-posterior notochord extension
at the ventral side of the tail.

text: Although rigidity and jamming transitions have been widely studied in physics
and material science, their importance in a number of biological processes, including
embryo development, tissue homeostasis, wound healing, and disease progression,
has only begun to be recognized in the past few years. The hypothesis that biological
systems can undergo rigidity/jamming transitions is attractive, as it would allow
these systems to change their material properties rapidly and strongly. However,
whether such transitions indeed occur in biological systems, how they are being
regulated, and what their physiological relevance might be, is still being debated.
Here, we review theoretical and experimental advances from the past few years,
focusing on the regulation and role of potential tissue rigidity transitions in
different biological processes.

text: A cell’s size affects the likelihood that it will die. But how is cell size
controlled in this context and how does cell size impact commitment to the cell
death fate? We present evidence that the caspase CED-3 interacts with the RhoGEF
ECT-2 in Caenorhabditis elegans neuroblasts that generate “unwanted” cells. We
propose that this interaction promotes polar actomyosin contractility, which leads
to unequal neuroblast division and the generation of a daughter cell that is below
the critical “lethal” size threshold. Furthermore, we find that hyperactivation
of ECT-2 RhoGEF reduces the sizes of unwanted cells. Importantly, this suppresses
the “cell death abnormal” phenotype caused by the partial loss of ced-3 caspase
and therefore increases the likelihood that unwanted cells die. A putative null
mutation of ced-3 caspase, however, is not suppressed, which indicates that cell
size affects CED-3 caspase activation and/or activity. Therefore, we have uncovered
novel sequential and reciprocal interactions between the apoptosis pathway and
cell size that impact a cell’s commitment to the cell death fate.

text: 'Lymph nodes (LNs) comprise two main structural elements: fibroblastic reticular
cells that form dedicated niches for immune cell interaction and capsular fibroblasts
that build a shell around the organ. Immunological challenge causes LNs to increase
more than tenfold in size within a few days. Here, we characterized the biomechanics
of LN swelling on the cellular and organ scale. We identified lymphocyte trapping
by influx and proliferation as drivers of an outward pressure force, causing fibroblastic
reticular cells of the T-zone (TRCs) and their associated conduits to stretch.
After an initial phase of relaxation, TRCs sensed the resulting strain through
cell matrix adhesions, which coordinated local growth and remodeling of the stromal
network. While the expanded TRC network readopted its typical configuration, a
massive fibrotic reaction of the organ capsule set in and countered further organ
expansion. Thus, different fibroblast populations mechanically control LN swelling
in a multitier fashion.'

text: Tension of the actomyosin cell cortex plays a key role in determining cell–cell
contact growth and size. The level of cortical tension outside of the cell–cell
contact, when pulling at the contact edge, scales with the total size to which
a cell–cell contact can grow [J.-L. Maître et al., Science 338, 253–256 (2012)].
Here, we show in zebrafish primary germ-layer progenitor cells that this monotonic
relationship only applies to a narrow range of cortical tension increase and that
above a critical threshold, contact size inversely scales with cortical tension.
This switch from cortical tension increasing to decreasing progenitor cell–cell
contact size is caused by cortical tension promoting E-cadherin anchoring to the
actomyosin cytoskeleton, thereby increasing clustering and stability of E-cadherin
at the contact. After tension-mediated E-cadherin stabilization at the contact
exceeds a critical threshold level, the rate by which the contact expands in response
to pulling forces from the cortex sharply drops, leading to smaller contacts at
physiologically relevant timescales of contact formation. Thus, the activity of
cortical tension in expanding cell–cell contact size is limited by tension-stabilizing
E-cadherin–actin complexes at the contact.

text: Upon the initiation of collective cell migration, the cells at the free edge
are specified as leader cells; however, the mechanism underlying the leader cell
specification remains elusive. Here, we show that lamellipodial extension after
the release from mechanical confinement causes sustained extracellular signal-regulated
kinase (ERK) activation and underlies the leader cell specification. Live-imaging
of Madin-Darby canine kidney (MDCK) cells and mouse epidermis through the use
of Förster resonance energy transfer (FRET)-based biosensors showed that leader
cells exhibit sustained ERK activation in a hepatocyte growth factor (HGF)-dependent
manner. Meanwhile, follower cells exhibit oscillatory ERK activation waves in
an epidermal growth factor (EGF) signaling-dependent manner. Lamellipodial extension
at the free edge increases the cellular sensitivity to HGF. The HGF-dependent
ERK activation, in turn, promotes lamellipodial extension, thereby forming a positive
feedback loop between cell extension and ERK activation and specifying the cells
at the free edge as the leader cells. Our findings show that the integration of
physical and biochemical cues underlies the leader cell specification during collective
cell migration.

text: "Metazoan development relies on the formation and remodeling of cell-cell
contacts. The \r\nbinding of adhesion receptors and remodeling of the actomyosin
cell cortex at cell-cell \r\ninteraction sites have been implicated in cell-cell
contact formation. Yet, how these two \r\nprocesses functionally interact to drive
cell-cell contact expansion and strengthening \r\nremains unclear. Here, we study
how primary germ layer progenitor cells from zebrafish \r\nbind to supported lipid
bilayers (SLB) functionalized with E-cadherin ectodomains as an \r\nassay system
for monitoring cell-cell contact formation at high spatiotemporal resolution.
\r\nWe show that cell-cell contact formation represents a two-tiered process:
E-cadherin\x02mediated downregulation of the small GTPase RhoA at the forming
contact leads to both \r\ndepletion of Myosin-2 and decrease of F-actin. This
is followed by centrifugal actin \r\nnetwork flows at the contact triggered by
a sharp gradient of Myosin-2 at the rim of the \r\ncontact zone, with Myosin-2
displaying higher cortical localization outside than inside of \r\nthe contact.
These centrifugal cortical actin flows, in turn, not only further dilute the actin
\r\nnetwork at the contact disc, but also lead to an accumulation of both F-actin
and E\x02cadherin at the contact rim. Eventually, this combination of actomyosin
downregulation \r\nand flows at the contact contribute to the characteristic molecular
organization implicated \r\nin contact formation and maintenance: depletion of
cortical actomyosin at the contact disc, \r\ndriving contact expansion by lowering
interfacial tension at the contact, and accumulation \r\nof both E-cadherin and
F-actin at the contact rim, mechanically linking the contractile \r\ncortices
of the adhering cells. Thus, using a biomimetic assay, we exemplify how \r\nadhesion
signaling and cell mechanics function together to modulate the spatial \r\norganization
of cell-cell contacts."

text: Mentorship is experience and/or knowledge‐based guidance. Mentors support,
sponsor and advocate for mentees. Having one or more mentors when you seek advice
can significantly influence and improve your research endeavours, well‐being and
career development. Positive mentee–mentor relationships are vital for maintaining
work–life balance and success in careers. Early‐career researchers (ECRs), in
particular, can benefit from mentorship to navigate challenges in academic and
nonacademic life and careers. Yet, strategies for selecting mentors and maintaining
interactions with them are often underdiscussed within research environments.
In this Words of Advice, we provide recommendations for ECRs to seek and manage
mentorship interactions. Our article draws from our experiences as ECRs and published
work, to provide suggestions for mentees to proactively promote beneficial mentorship
interactions. The recommended practices highlight the importance of identifying
mentorship needs, planning and selecting multiple and diverse mentors, setting
goals, and maintaining constructive, and mutually beneficial working relationships
with mentors.

text: Signaling by the B cell antigen receptor (BCR) initiates actin remodeling.
The assembly of branched actin networks that are nucleated by the Arp2/3 complex
exert outward force on the plasma membrane, allowing B cells to form membrane
protrusions that can scan the surface of antigen-presenting cells (APCs). The
resulting Arp2/3 complex-dependent actin retrograde flow promotes the centripetal
movement and progressive coalescence of BCR microclusters, which amplifies BCR
signaling. Glia maturation factor γ (GMFγ) is an actin disassembly-protein that
releases Arp2/3 complex-nucleated actin filaments from actin networks. By doing
so, GMFγ could either oppose the actions of the Arp2/3 complex or support Arp2/3
complex-nucleated actin polymerization by contributing to the recycling of actin
monomers and Arp2/3 complexes. We now show that reducing the levels of GMFγ in
human B cell lines via transfection with a specific siRNA impairs the ability
of B cells to spread on antigen-coated surfaces, decreases the velocity of actin
retrograde flow, diminishes the coalescence of BCR microclusters into a central
cluster at the B cell-APC contact site, and decreases APC-induced BCR signaling.
These effects of depleting GMFγ are similar to what occurs when the Arp2/3 complex
is inhibited. This suggests that GMFγ cooperates with the Arp2/3 complex to support
BCR-induced actin remodeling and amplify BCR signaling at the immune synapse.

text: Cell division orientation is thought to result from a competition between
cell geometry and polarity domains controlling the position of the mitotic spindle
during mitosis. Depending on the level of cell shape anisotropy or the strength
of the polarity domain, one dominates the other and determines the orientation
of the spindle. Whether and how such competition is also at work to determine
unequal cell division (UCD), producing daughter cells of different size, remains
unclear. Here, we show that cell geometry and polarity domains cooperate, rather
than compete, in positioning the cleavage plane during UCDs in early ascidian
embryos. We found that the UCDs and their orientation at the ascidian third cleavage
rely on the spindle tilting in an anisotropic cell shape, and cortical polarity
domains exerting different effects on spindle astral microtubules. By systematically
varying mitotic cell shape, we could modulate the effect of attractive and repulsive
polarity domains and consequently generate predicted daughter cell size asymmetries
and position. We therefore propose that the spindle position during UCD is set
by the combined activities of cell geometry and polarity domains, where cell geometry
modulates the effect of cortical polarity domain(s).

text: Tissue morphogenesis is driven by mechanical forces triggering cell movements
and shape changes. Quantitatively measuring tension within tissues is of great
importance for understanding the role of mechanical signals acting on the cell
and tissue level during morphogenesis. Here we introduce laser ablation as a useful
tool to probe tissue tension within the granulosa layer, an epithelial monolayer
of somatic cells that surround the zebrafish female gamete during folliculogenesis.
We describe in detail how to isolate follicles, mount samples, perform laser surgery,
and analyze the data.

text: Embryo morphogenesis is impacted by dynamic changes in tissue material properties,
which have been proposed to occur via processes akin to phase transitions (PTs).
Here, we show that rigidity percolation provides a simple and robust theoretical
framework to predict material/structural PTs of embryonic tissues from local cell
connectivity. By using percolation theory, combined with directly monitoring dynamic
changes in tissue rheology and cell contact mechanics, we demonstrate that the
zebrafish blastoderm undergoes a genuine rigidity PT, brought about by a small
reduction in adhesion-dependent cell connectivity below a critical value. We quantitatively
predict and experimentally verify hallmarks of PTs, including power-law exponents
and associated discontinuities of macroscopic observables. Finally, we show that
this uniform PT depends on blastoderm cells undergoing meta-synchronous divisions
causing random and, consequently, uniform changes in cell connectivity. Collectively,
our theoretical and experimental findings reveal the structural basis of material
PTs in an organismal context.

text: When B cells encounter membrane-bound antigens, the formation and coalescence
of B cell antigen receptor (BCR) microclusters amplifies BCR signaling. The ability
of B cells to probe the surface of antigen-presenting cells (APCs) and respond
to APC-bound antigens requires remodeling of the actin cytoskeleton. Initial BCR
signaling stimulates actin-related protein (Arp) 2/3 complex-dependent actin polymerization,
which drives B cell spreading as well as the centripetal movement and coalescence
of BCR microclusters at the B cell-APC synapse. Sustained actin polymerization
depends on concomitant actin filament depolymerization, which enables the recycling
of actin monomers and Arp2/3 complexes. Cofilin-mediated severing of actin filaments
is a rate-limiting step in the morphological changes that occur during immune
synapse formation. Hence, regulators of cofilin activity such as WD repeat-containing
protein 1 (Wdr1), LIM domain kinase (LIMK), and coactosin-like 1 (Cotl1) may also
be essential for actin-dependent processes in B cells. Wdr1 enhances cofilin-mediated
actin disassembly. Conversely, Cotl1 competes with cofilin for binding to actin
and LIMK phosphorylates cofilin and prevents it from binding to actin filaments.
We now show that Wdr1 and LIMK have distinct roles in BCR-induced assembly of
the peripheral actin structures that drive B cell spreading, and that cofilin,
Wdr1, and LIMK all contribute to the actin-dependent amplification of BCR signaling
at the immune synapse. Depleting Cotl1 had no effect on these processes. Thus,
the Wdr1-LIMK-cofilin axis is critical for BCR-induced actin remodeling and for
B cell responses to APC-bound antigens.

text: 'The developmental strategies used by progenitor cells to endure a safe journey
from their induction place towards the site of terminal differentiation are still
poorly understood. Here we uncovered a progenitor cell allocation mechanism that
stems from an incomplete process of epithelial delamination that allows progenitors
to coordinate their movement with adjacent extra-embryonic tissues. Progenitors
of the zebrafish laterality organ originate from the surface epithelial enveloping
layer by an apical constriction process of cell delamination. During this process,
progenitors retain long-term apical contacts that enable the epithelial layer
to pull a subset of progenitors along their way towards the vegetal pole. The
remaining delaminated progenitors follow apically-attached progenitors’ movement
by a co-attraction mechanism, avoiding sequestration by the adjacent endoderm,
ensuring their fate and collective allocation at the differentiation site. Thus,
we reveal that incomplete delamination serves as a cellular platform for coordinated
tissue movements during development. Impact Statement: Incomplete delamination
serves as a cellular platform for coordinated tissue movements during development,
guiding newly formed progenitor cell groups to the differentiation site.'

Here, we have addressed the involvement of chromatin organizer Satb2 in orchestrating
both processes during zebrafish embryogenesis. Integrative analysis of transcriptome,
genome-wide occupancy and chromatin accessibility reveals contrasting molecular
activities of maternally deposited and zygotically synthesized Satb2. Maternal
Satb2 prevents premature transcription of zygotic genes by influencing the interplay
between the pluripotency factors. By contrast, zygotic Satb2 activates transcription
of the same group of genes during neural crest development and organogenesis.
Thus, our comparative analysis of maternal versus zygotic function of Satb2 underscores
how these antithetical activities are temporally coordinated and functionally
implemented highlighting the evolutionary implications of the biphasic and bimodal
regulation of landmark developmental transitions by a single determinant.
