text: Cellular plasticity, the ability of a differentiated cell to adopt another
phenotypic identity, is restricted under basal conditions, but can be elicited
upon damage. However, the molecular mechanism enabling such plasticity remains
largely unexplored. Here, we report damage-induced cellular plasticity of secretory
enteroendocrine cells (EEs) in the adult Drosophila midgut. Ionizing radiation
induces EE fate conversion and activates stress-responsive programs in EE lineages,
accompanied by the induction of the stress-inducible transcription factor Xrp1
and the cytokine gene upd3. Xrp1 and upd3 are both necessary for radiation-induced
EE plasticity. Under basal conditions, EE-specific Xrp1 overexpression triggers
ectopic expression of progenitor-specific genes, which is necessary for Xrp1 to
drive EE plasticity. Our work identifies Xrp1 as a crucial regulator that coordinates
damage-induced signaling and transcriptional reprogramming, enabling the reactivation
of cellular plasticity in differentiated cells.

text: 'During embryonic development, cell behaviors need to be tightly regulated
in time and space. Yet how the temporal and spatial regulations of cell behaviors
are interconnected during embryonic development remains elusive. To address this,
we turned to zebrafish gastrulation, the process whereby dynamic cell behaviors
generate the three principal germ layers of the early embryo. Here, we show that
Hoxb cluster genes are expressed in a temporally collinear manner at the blastoderm
margin, where mesodermal and endodermal (mesendoderm) progenitor cells are specified
and ingress to form mesendoderm/hypoblast. Functional analysis shows that these
Hoxb genes regulate the timing of cell ingression: under- or overexpression of
Hoxb genes perturb the timing of mesendoderm cell ingression and, consequently,
the positioning of these cells along the forming anterior-posterior body axis
after gastrulation. Finally, we found that Hoxb genes control the timing of mesendoderm
ingression by regulating cellular bleb formation and cell surface fluctuations
in the ingressing cells. Collectively, our findings suggest that Hoxb genes interconnect
the temporal and spatial pattern of cell behaviors during zebrafish gastrulation
by controlling cell surface fluctuations.'

text: Changes in gene dosage can have tremendous evolutionary potential (e.g. whole-genome
duplications), but without compensatory mechanisms, they can also lead to gene
dysregulation and pathologies. Sex chromosomes are a paradigmatic example of naturally
occurring gene dosage differences and their compensation. In species with chromosome-based
sex determination, individuals within the same population necessarily show ‘natural’
differences in gene dosage for the sex chromosomes. In this Review, we focus on
the mammalian X chromosome and discuss recent new insights into the dosage-compensation
mechanisms that evolved along with the emergence of sex chromosomes, namely X-inactivation
and X-upregulation. We also discuss the evolution of the genetic loci and molecular
players involved, as well as the regulatory diversity and potentially different
requirements for dosage compensation across mammalian species.

text: Embryogenesis results from the coordinated activities of different signaling
pathways controlling cell fate specification and morphogenesis. In vertebrate
gastrulation, both Nodal and BMP signaling play key roles in germ layer specification
and morphogenesis, yet their interplay to coordinate embryo patterning with morphogenesis
is still insufficiently understood. Here, we took a reductionist approach using
zebrafish embryonic explants to study the coordination of Nodal and BMP signaling
for embryo patterning and morphogenesis. We show that Nodal signaling triggers
explant elongation by inducing mesendodermal progenitors but also suppressing
BMP signaling activity at the site of mesendoderm induction. Consistent with this,
ectopic BMP signaling in the mesendoderm blocks cell alignment and oriented mesendoderm
intercalations, key processes during explant elongation. Translating these ex
vivo observations to the intact embryo showed that, similar to explants, Nodal
signaling suppresses the effect of BMP signaling on cell intercalations in the
dorsal domain, thus allowing robust embryonic axis elongation. These findings
suggest a dual function of Nodal signaling in embryonic axis elongation by both
inducing mesendoderm and suppressing BMP effects in the dorsal portion of the
mesendoderm.

text: During neural development, cellular adhesion is crucial for interactions among
and between neurons and surrounding tissues. This function is mediated by conserved
cell adhesion molecules, which are tightly regulated to allow for coordinated
neuronal outgrowth. Here, we show that the proprotein convertase KPC-1 (homolog
of mammalian furin) regulates the Menorin adhesion complex during development
of PVD dendritic arbors in Caenorhabditis elegans. We found a finely regulated
antagonistic balance between PVD-expressed KPC-1 and the epidermally expressed
putative cell adhesion molecule MNR-1 (Menorin). Genetically, partial loss of
mnr-1 suppressed partial loss of kpc-1, and both loss of kpc-1 and transgenic
overexpression of mnr-1 resulted in indistinguishable phenotypes in PVD dendrites.
This balance regulated cell-surface localization of the DMA-1 leucine-rich transmembrane
receptor in PVD neurons. Lastly, kpc-1 mutants showed increased amounts of MNR-1
and decreased amounts of muscle-derived LECT-2 (Chondromodulin II), which is also
part of the Menorin adhesion complex. These observations suggest that KPC-1 in
PVD neurons directly or indirectly controls the abundance of proteins of the Menorin
adhesion complex from adjacent tissues, thereby providing negative feedback from
the dendrite to the instructive cues of surrounding tissues.

text: Morphogen gradients impart positional information to cells in a homogenous
tissue field. Fgf8a, a highly conserved growth factor, has been proposed to act
as a morphogen during zebrafish gastrulation. However, technical limitations have
so far prevented direct visualization of the endogenous Fgf8a gradient and confirmation
of its morphogenic activity. Here, we monitor Fgf8a propagation in the developing
neural plate using a CRISPR/Cas9-mediated EGFP knock-in at the endogenous fgf8a
locus. By combining sensitive imaging with single-molecule fluorescence correlation
spectroscopy, we demonstrate that Fgf8a, which is produced at the embryonic margin,
propagates by diffusion through the extracellular space and forms a graded distribution
towards the animal pole. Overlaying the Fgf8a gradient curve with expression profiles
of its downstream targets determines the precise input-output relationship of
Fgf8a-mediated patterning. Manipulation of the extracellular Fgf8a levels alters
the signaling outcome, thus establishing Fgf8a as a bona fide morphogen during
zebrafish gastrulation. Furthermore, by hindering Fgf8a diffusion, we demonstrate
that extracellular diffusion of the protein from the source is crucial for it
to achieve its morphogenic potential.

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: MicroRNAs (miRs) have an important role in tuning dynamic gene expression.
However, the mechanism by which they are quantitatively controlled is unknown.
We show that the amount of mature miR-9, a key regulator of neuronal development,
increases during zebrafish neurogenesis in a sharp stepwise manner. We characterize
the spatiotemporal profile of seven distinct microRNA primary transcripts (pri-mir)-9s
that produce the same mature miR-9 and show that they are sequentially expressed
during hindbrain neurogenesis. Expression of late-onset pri-mir-9-1 is added on
to, rather than replacing, the expression of early onset pri-mir-9-4 and -9-5
in single cells. CRISPR/Cas9 mutation of the late-onset pri-mir-9-1 prevents the
developmental increase of mature miR-9, reduces late neuronal differentiation
and fails to downregulate Her6 at late stages. Mathematical modelling shows that
an adaptive network containing Her6 is insensitive to linear increases in miR-9
but responds to stepwise increases of miR-9. We suggest that a sharp stepwise
increase of mature miR-9 is created by sequential and additive temporal activation
of distinct loci. This may be a strategy to overcome adaptation and facilitate
a transition of Her6 to a new dynamic regime or steady state.

text: The Hunchback (Hb) transcription factor is crucial for anterior-posterior
patterning of the Drosophila embryo. The maternal hb mRNA acts as a paradigm for
translational regulation due to its repression in the posterior of the embryo.
However, little is known about the translatability of zygotically transcribed
hb mRNAs. Here, we adapt the SunTag system, developed for imaging translation
at single-mRNA resolution in tissue culture cells, to the Drosophila embryo to
study the translation dynamics of zygotic hb mRNAs. Using single-molecule imaging
in fixed and live embryos, we provide evidence for translational repression of
zygotic SunTag-hb mRNAs. Whereas the proportion of SunTag-hb mRNAs translated
is initially uniform, translation declines from the anterior over time until it
becomes restricted to a posterior band in the expression domain. We discuss how
regulated hb mRNA translation may help establish the sharp Hb expression boundary,
which is a model for precision and noise during developmental patterning. Overall,
our data show how use of the SunTag method on fixed and live embryos is a powerful
combination for elucidating spatiotemporal regulation of mRNA translation in Drosophila.

text: Cell division, movement and differentiation contribute to pattern formation
in developing tissues. This is the case in the vertebrate neural tube, in which
neurons differentiate in a characteristic pattern from a highly dynamic proliferating
pseudostratified epithelium. To investigate how progenitor proliferation and differentiation
affect cell arrangement and growth of the neural tube, we used experimental measurements
to develop a mechanical model of the apical surface of the neuroepithelium that
incorporates the effect of interkinetic nuclear movement and spatially varying
rates of neuronal differentiation. Simulations predict that tissue growth and
the shape of lineage-related clones of cells differ with the rate of differentiation.
Growth is isotropic in regions of high differentiation, but dorsoventrally biased
in regions of low differentiation. This is consistent with experimental observations.
The absence of directional signalling in the simulations indicates that global
mechanical constraints are sufficient to explain the observed differences in anisotropy.
This provides insight into how the tissue growth rate affects cell dynamics and
growth anisotropy and opens up possibilities to study the coupling between mechanics,
pattern formation and growth in the neural tube.

text: The formation of neuronal dendrite branches is fundamental for the wiring
and function of the nervous system. Indeed, dendrite branching enhances the coverage
of the neuron's receptive field and modulates the initial processing of incoming
stimuli. Complex dendrite patterns are achieved in vivo through a dynamic process
of de novo branch formation, branch extension and retraction. The first step towards
branch formation is the generation of a dynamic filopodium-like branchlet. The
mechanisms underlying the initiation of dendrite branchlets are therefore crucial
to the shaping of dendrites. Through in vivo time-lapse imaging of the subcellular
localization of actin during the process of branching of Drosophila larva sensory
neurons, combined with genetic analysis and electron tomography, we have identified
the Actin-related protein (Arp) 2/3 complex as the major actin nucleator involved
in the initiation of dendrite branchlet formation, under the control of the activator
WAVE and of the small GTPase Rac1. Transient recruitment of an Arp2/3 component
marks the site of branchlet initiation in vivo. These data position the activation
of Arp2/3 as an early hub for the initiation of branchlet formation.

text: In November 2016, developmental biologists, synthetic biologists and engineers
gathered in Paris for a meeting called ‘Engineering the embryo’. The participants
shared an interest in exploring how synthetic systems can reveal new principles
of embryonic development, and how the in vitro manipulation and modeling of development
using stem cells can be used to integrate ideas and expertise from physics, developmental
biology and tissue engineering. As we review here, the conference pinpointed some
of the challenges arising at the intersection of these fields, along with great
enthusiasm for finding new approaches and collaborations.

text: The segregation of different cell types into distinct tissues is a fundamental
process in metazoan development. Differences in cell adhesion and cortex tension
are commonly thought to drive cell sorting by regulating tissue surface tension
(TST). However, the role that differential TST plays in cell segregation within
the developing embryo is as yet unclear. Here, we have analyzed the role of differential
TST for germ layer progenitor cell segregation during zebrafish gastrulation.
Contrary to previous observations that differential TST drives germ layer progenitor
cell segregation in vitro, we show that germ layers display indistinguishable
TST within the gastrulating embryo, arguing against differential TST driving germ
layer progenitor cell segregation in vivo. We further show that the osmolarity
of the interstitial fluid (IF) is an important factor that influences germ layer
TST in vivo, and that lower osmolarity of the IF compared with standard cell culture
medium can explain why germ layers display differential TST in culture but not
in vivo. Finally, we show that directed migration of mesendoderm progenitors is
required for germ layer progenitor cell segregation and germ layer formation.

text: The four microsporangia of the flowering plant anther develop from archesporial
cells in the L2 of the primordium. Within each microsporangium, developing microsporocytes
are surrounded by concentric monolayers of tapetal, middle layer and endothecial
cells. How this intricate array of tissues, each containing relatively few cells,
is established in an organ possessing no formal meristems is poorly understood.
We describe here the pivotal role of the LRR receptor kinase EXCESS MICROSPOROCYTES
1 (EMS1) in forming the monolayer of tapetal nurse cells in Arabidopsis. Unusually
for plants, tapetal cells are specified very early in development, and are subsequently
stimulated to proliferate by a receptor-like kinase (RLK) complex that includes
EMS1. Mutations in members of this EMS1 signalling complex and its putative ligand
result in male-sterile plants in which tapetal initials fail to proliferate. Surprisingly,
these cells continue to develop, isolated at the locular periphery. Mutant and
wild-type microsporangia expand at similar rates and the ‘tapetal’ space at the
periphery of mutant locules becomes occupied by microsporocytes. However, induction
of late expression of EMS1 in the few tapetal initials in ems1 plants results
in their proliferation to generate a functional tapetum, and this proliferation
suppresses microsporocyte number. Our experiments also show that integrity of
the tapetal monolayer is crucial for the maintenance of the polarity of divisions
within it. This unexpected autonomy of the tapetal ‘lineage’ is discussed in the
context of tissue development in complex plant organs, where constancy in size,
shape and cell number is crucial.

text: Handedness of the vertebrate body plan critically depends on transient embryonic
structures/ organs that generate cilia-dependent leftward fluid flow within constrained
extracellular environments. Although the function of ciliated organs in laterality
determination has been extensively studied, how they are formed during embryogenesis
is still poorly understood. Here we show that Kupffer's vesicle (KV), the zebrafish
organ of laterality, arises from a surface epithelium previously thought to adopt
exclusively extra-embryonic fates. Live multi-photon confocal imaging reveals
that surface epithelial cells undergo Nodal/TGF beta signalling-dependent ingression
at the dorsal germ ring margin prior to gastrulation, to give rise to dorsal forerunner
cells (DFCs), the precursors of KV. DFCs then migrate attached to the overlying
surface epithelium and rearrange into rosette-like epithelial structures at the
end of gastrulation. During early somitogenesis, these epithelial rosettes coalesce
into a single rosette that differentiates into the KV with a ciliated lumen at
its apical centre. Our results provide novel insights into the morphogenetic transformations
that shape the laterality organ in zebrafish and suggest a conserved progenitor
role of the surface epithelium during laterality organ formation in vertebrates.

text: Cytosine methylation is the most common covalent modification of DNA in eukaryotes.
DNA methylation has an important role in many aspects of biology, including development
and disease. Methylation can be detected using bisulfite conversion, methylation-sensitive
restriction enzymes, methyl-binding proteins and anti-methylcytosine antibodies.
Combining these techniques with DNA microarrays and high-throughput sequencing
has made the mapping of DNA methylation feasible on a genome-wide scale. Here
we discuss recent developments and future directions for identifying and mapping
methylation, in an effort to help colleagues to identify the approaches that best
serve their research interests.

text: Epithelial morphogenesis depends on coordinated changes in cell shape, a process
that is still poorly understood. During zebrafish epiboly and Drosophila dorsal
closure, cell-shape changes at the epithelial margin are of critical importance.
Here evidence is provided for a conserved mechanism of local actin and myosin
2 recruitment during theses events. It was found that during epiboly of the zebrafish
embryo, the movement of the outer epithelium (enveloping layer) over the yolk
cell surface involves the constriction of marginal cells. This process depends
on the recruitment of actin and myosin 2 within the yolk cytoplasm along the margin
of the enveloping layer. Actin and myosin 2 recruitment within the yolk cytoplasm
requires the Ste20-like kinase Msn1, an orthologue of Drosophila Misshapen. Similarly,
in Drosophila, actin and myosin 2 localization and cell constriction at the margin
of the epidermis mediate dorsal closure and are controlled by Misshapen. Thus,
this study has characterized a conserved mechanism underlying coordinated cell-shape
changes during epithelial morphogenesis.

text: 'Plant development displays an exceptional plasticity and adaptability that
involves the dynamic, asymmetric distribution of the phytohormone auxin. Polar
auxin flow, which requires polarly localized transport facilitators of the PIN
family, largely contributes to the establishment and maintenance of the auxin
gradients. Functionally overlapping action of PIN proteins mediates multiple developmental
processes, including embryo formation, organ development and tropisms. Here we
show that PIN proteins exhibit synergistic interactions, which involve cross-regulation
of PIN gene expression in pin mutants or plants with inhibited auxin transport.
Auxin itself positively feeds back on PIN gene expression in a tissue-specific
manner through an AUX/IAA-dependent signalling pathway. This regulatory switch
is indicative of a mechanism by which the loss of a specific PIN protein is compensated
for by auxin-dependent ectopic: expression of its homologues. The compensatory
properties of the PIN-dependent transport network might enable the stabilization
of auxin gradients and potentially contribute to the robustness of plant adaptive
development.'

text: We have identified widerborst (wdb), a B' regulatory subunit of PP2A, as a
conserved component of planar cell polarization mechanisms in both Drosophila
and in zebrafish. In Drosophila, wdb acts at two steps during planar polarization
of wing epithelial cells. It is required to organize tissue polarity proteins
into proximal and distal cortical domains, thus determining wing hair orientation.
It is also needed to generate the polarized membrane outgrowth that becomes the
wing hair. Widerborst activates the catalytic subunit of PP2A and localizes to
the distal side of a planar microtubule web that lies at the level of apical cell
junctions. This suggests that polarized PP2A activation along the planar microtubule
web is important for planar polarization. In zebrafish, two wdb homologs are required
for convergent extension during gastrulation, supporting the conjecture that Drosophila
planar cell polarization and vertebrate gastrulation movements are regulated by
similar mechanisms.

text: During the development of the zebrafish nervous system both noi, a zebrafish
pax2 homolog, and ace, a zebrafish fgf8 homolog, are required for development
of the midbrain and cerebellum. Here we describe a dominant mutation, aussicht
(aus), in which the expression of noi and ace is upregulated, In aus mutant embryos,
ace is upregulated at many sites in the embryo, while Itoi expression is only
upregulated in regions of the forebrain and midbrain which also express ace. Subsequent
to the alterations in noi and ace expression, aus mutants exhibit defects in the
differentiation of the forebrain, midbrain and eyes. Within the forebrain, the
formation of the anterior and postoptic commissures is delayed and the expression
of markers within the pretectal area is reduced. Within the midbrain, En and wnt1
expression is expanded. In heterozygous aus embryos, there is ectopic outgrowth
of neural retina in the temporal half of the eyes, whereas in putative homozygous
aus embryos, the ventral retina is reduced and the pigmented retinal epithelium
is expanded towards the midline, The observation that ans mutant embryos exhibit
widespread upregulation of ace raised the possibility that aus might represent
an allele of the ace gene itself. However, by crossing carriers for both aus and
ace, we were able to generate homozygous ace mutant embryos that also exhibited
the aus phenotype, This indicated that aus is not tightly linked to ace and is
unlikely to be a mutation directly affecting the ace locus. However, increased
Ace activity may underly many aspects of the aus phenotype and we show that the
upregulation of noi in the forebrain of aus mutants is partially dependent upon
functional Ace activity. Conversely, increased ace expression in the forebrain
of arcs mutants is not dependent upon functional Noi activity. We conclude that
aus represents a mutation involving a locus normally required for the regulation
of ace expression during embryogenesis.
