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: Animal development entails the organization of specific cell types in space
and time, and spatial patterns must form in a robust manner. In the zebrafish
spinal cord, neural progenitors form stereotypic patterns despite noisy morphogen
signaling and large-scale cellular rearrangements during morphogenesis and growth.
By directly measuring adhesion forces and preferences for three types of endogenous
neural progenitors, we provide evidence for the differential adhesion model in
which differences in intercellular adhesion mediate cell sorting. Cell type–specific
combinatorial expression of different classes of cadherins (N-cadherin, cadherin
11, and protocadherin 19) results in homotypic preference ex vivo and patterning
robustness in vivo. Furthermore, the differential adhesion code is regulated by
the sonic hedgehog morphogen gradient. We propose that robust patterning during
tissue morphogenesis results from interplay between adhesion-based self-organization
and morphogen-directed patterning.

text: Cell fate specification by lateral inhibition typically involves contact signaling
through the Delta-Notch signaling pathway. However, whether this is the only signaling
mode mediating lateral inhibition remains unclear. Here we show that in zebrafish
oogenesis, a group of cells within the granulosa cell layer at the oocyte animal
pole acquire elevated levels of the transcriptional coactivator TAZ in their nuclei.
One of these cells, the future micropyle precursor cell (MPC), accumulates increasingly
high levels of nuclear TAZ and grows faster than its surrounding cells, mechanically
compressing those cells, which ultimately lose TAZ from their nuclei. Strikingly,
relieving neighbor-cell compression by MPC ablation or aspiration restores nuclear
TAZ accumulation in neighboring cells, eventually leading to MPC re-specification
from these cells. Conversely, MPC specification is defective in taz−/− follicles.
These findings uncover a novel mode of lateral inhibition in cell fate specification
based on mechanical signals controlling TAZ activity.

text: Intra-organ communication guides morphogenetic processes that are essential
for an organ to carry out complex physiological functions. In the heart, the growth
of the myocardium is tightly coupled to that of the endocardium, a specialized
endothelial tissue that lines its interior. Several molecular pathways have been
implicated in the communication between these tissues including secreted factors,
components of the extracellular matrix, or proteins involved in cell-cell communication.
Yet, it is unknown how the growth of the endocardium is coordinated with that
of the myocardium. Here, we show that an increased expansion of the myocardial
atrial chamber volume generates higher junctional forces within endocardial cells.
This leads to biomechanical signaling involving VE-cadherin, triggering nuclear
localization of the Hippo pathway transcriptional regulator Yap1 and endocardial
proliferation. Our work suggests that the growth of the endocardium results from
myocardial chamber volume expansion and ends when the tension on the tissue is
relaxed.
