text: Tissue morphogenesis and patterning during development involve the segregation
of cell types. Segregation is driven by differential tissue surface tensions generated
by cell types through controlling cell-cell contact formation by regulating adhesion
and actomyosin contractility-based cellular cortical tensions. We use vertebrate
tissue cell types and zebrafish germ layer progenitors as in vitro models of 3-dimensional
heterotypic segregation and developed a quantitative analysis of their dynamics
based on 3D time-lapse microscopy. We show that general inhibition of actomyosin
contractility by the Rho kinase inhibitor Y27632 delays segregation. Cell type-specific
inhibition of non-muscle myosin2 activity by overexpression of myosin assembly
inhibitor S100A4 reduces tissue surface tension, manifested in decreased compaction
during aggregation and inverted geometry observed during segregation. The same
is observed when we express a constitutively active Rho kinase isoform to ubiquitously
keep actomyosin contractility high at cell-cell and cell-medium interfaces and
thus overriding the interface-specific regulation of cortical tensions. Tissue
surface tension regulation can become an effective tool in tissue engineering.

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: Cell-cell contact formation constitutes an essential step in evolution, leading
to the differentiation of specialized cell types. However, remarkably little is
known about whether and how the interplay between contact formation and fate specification
affects development. Here, we identify a positive feedback loop between cell-cell
contact duration, morphogen signaling, and mesendoderm cell-fate specification
during zebrafish gastrulation. We show that long-lasting cell-cell contacts enhance
the competence of prechordal plate (ppl) progenitor cells to respond to Nodal
signaling, required for ppl cell-fate specification. We further show that Nodal
signaling promotes ppl cell-cell contact duration, generating a positive feedback
loop between ppl cell-cell contact duration and cell-fate specification. Finally,
by combining mathematical modeling and experimentation, we show that this feedback
determines whether anterior axial mesendoderm cells become ppl or, instead, turn
into endoderm. Thus, the interdependent activities of cell-cell signaling and
contact formation control fate diversification within the developing embryo.

text: Roots navigate through soil integrating environmental signals to orient their
growth. The Arabidopsis root is a widely used model for developmental, physiological
and cell biological studies. Live imaging greatly aids these efforts, but the
horizontal sample position and continuous root tip displacement present significant
difficulties. Here, we develop a confocal microscope setup for vertical sample
mounting and integrated directional illumination. We present TipTracker – a custom
software for automatic tracking of diverse moving objects usable on various microscope
setups. Combined, this enables observation of root tips growing along the natural
gravity vector over prolonged periods of time, as well as the ability to induce
rapid gravity or light stimulation. We also track migrating cells in the developing
zebrafish embryo, demonstrating the utility of this system in the acquisition
of high-resolution data sets of dynamic samples. We provide detailed descriptions
of the tools enabling the easy implementation on other microscopes.

text: Cell-cell contact formation constitutes the first step in the emergence of multicellularity in
evolution, thereby allowing the differentiation of specialized cell types. In metazoan
development, cell-cell contact formation is thought to influence cell fate specification,
and cell fate specification has been implicated in cell-cell contact
formation. However, remarkably little is yet known about whether and how the
interaction and feedback between cell-cell contact formation and cell fate specification
affect development. Here we identify a positive feedback loop between cell-cell contact duration, morphogen signaling and
mesendoderm cell fate specification during zebrafish gastrulation. We show that long
lasting cell-cell contacts enhance the competence of prechordal plate (ppl) progenitor
cells to respond to Nodal signaling, required for proper ppl cell fate specification. We further
show that Nodal signalling romotes ppl cell-cell contact duration, thereby generating an
effective positive feedback loop between ppl cell-cell contact duration and cell fate
specification. Finally, by using a combination of theoretical modeling and experimentation,
we show that this feedback loop determines whether anterior axial mesendoderm cells
become ppl progenitors or, instead, turn into endoderm progenitors. Our findings reveal
that the gene regulatory networks leading to cell fate diversification within the developing
embryo are controlled by the interdependent activities of cell-cell signaling and contact
formation.

text: During metazoan development, the temporal pattern of morphogen signaling is
critical for organizing cell fates in space and time. Yet, tools for temporally
controlling morphogen signaling within the embryo are still scarce. Here, we developed
a photoactivatable Nodal receptor to determine how the temporal pattern of Nodal
signaling affects cell fate specification during zebrafish gastrulation. By using
this receptor to manipulate the duration of Nodal signaling in vivo by light,
we show that extended Nodal signaling within the organizer promotes prechordal
plate specification and suppresses endoderm differentiation. Endoderm differentiation
is suppressed by extended Nodal signaling inducing expression of the transcriptional
repressor goosecoid (gsc) in prechordal plate progenitors, which in turn restrains
Nodal signaling from upregulating the endoderm differentiation gene sox17 within
these cells. Thus, optogenetic manipulation of Nodal signaling identifies a critical
role of Nodal signaling duration for organizer cell fate specification during
gastrulation.

text: 3D amoeboid cell migration is central to many developmental and disease-related
processes such as cancer metastasis. Here, we identify a unique prototypic amoeboid
cell migration mode in early zebrafish embryos, termed stable-bleb migration.
Stable-bleb cells display an invariant polarized balloon-like shape with exceptional
migration speed and persistence. Progenitor cells can be reversibly transformed
into stable-bleb cells irrespective of their primary fate and motile characteristics
by increasing myosin II activity through biochemical or mechanical stimuli. Using
a combination of theory and experiments, we show that, in stable-bleb cells, cortical
contractility fluctuations trigger a stochastic switch into amoeboid motility,
and a positive feedback between cortical flows and gradients in contractility
maintains stable-bleb cell polarization. We further show that rearward cortical
flows drive stable-bleb cell migration in various adhesive and non-adhesive environments,
unraveling a highly versatile amoeboid migration phenotype.

text: Kupffer's vesicle (KV) is the zebrafish organ of laterality, patterning the
embryo along its left-right (LR) axis. Regional differences in cell shape within
the lumen-lining KV epithelium are essential for its LR patterning function. However,
the processes by which KV cells acquire their characteristic shapes are largely
unknown. Here, we show that the notochord induces regional differences in cell
shape within KV by triggering extracellular matrix (ECM) accumulation adjacent
to anterior-dorsal (AD) regions of KV. This localized ECM deposition restricts
apical expansion of lumen-lining epithelial cells in AD regions of KV during lumen
growth. Our study provides mechanistic insight into the processes by which KV
translates global embryonic patterning into regional cell shape differences required
for its LR symmetry-breaking function.

text: To fight infectious diseases, host immune defenses are employed at multiple
levels. Sanitary behavior, such as pathogen avoidance and removal, acts as a first
line of defense to prevent infection [1] before activation of the physiological
immune system. Insect societies have evolved a wide range of collective hygiene
measures and intensive health care toward pathogen-exposed group members [2].
One of the most common behaviors is allogrooming, in which nestmates remove infectious
particles from the body surfaces of exposed individuals [3]. Here we show that,
in invasive garden ants, grooming of fungus-exposed brood is effective beyond
the sheer mechanical removal of fungal conidiospores; it also includes chemical
disinfection through the application of poison produced by the ants themselves.
Formic acid is the main active component of the poison. It inhibits fungal growth
of conidiospores remaining on the brood surface after grooming and also those
collected in the mouth of the grooming ant. This dual function is achieved by
uptake of the poison droplet into the mouth through acidopore self-grooming and
subsequent application onto the infectious brood via brood grooming. This extraordinary
behavior extends the current understanding of grooming and the establishment of
social immunity in insect societies.

text: Visualizing and analyzing shape changes at various scales, ranging from single
molecules to whole organisms, are essential for understanding complex morphogenetic
processes, such as early embryonic development. Embryo morphogenesis relies on
the interplay between different tissues, the properties of which are again determined
by the interaction between their constituent cells. Cell interactions, on the
other hand, are controlled by various molecules, such as signaling and adhesion
molecules, which in order to exert their functions need to be spatiotemporally
organized within and between the interacting cells. In this review, we will focus
on the role of cell adhesion functioning at different scales to organize cell,
tissue and embryo morphogenesis. We will specifically ask how the subcellular
distribution of adhesion molecules controls the formation of cell-cell contacts,
how cell-cell contacts determine tissue shape, and how tissue interactions regulate
embryo morphogenesis.
