Hindgut specification and cell-adhesion functions of Sphox11/13b in the endoderm of the sea urchin embryo [PDF]
, 2006 Sphox11/13b is one of the two hox genes of Strongylocentrotus purpuratus expressed in the embryo. Its dynamic pattern of expression begins during gastrulation, when the transcripts are transiently located in a ring of cells at the edge of the ...

A Developmental Requirement for HIRA-Dependent H3.3 Deposition Revealed at Gastrulation in Xenopus
Cell Reports, 2012 Discovering how histone variants that mark distinct chromatin regions affect a developmental program is a major challenge in the epigenetics field. To assess the importance of the H3.3 histone variant and its dedicated histone chaperone HIRA, we used an ...

Morphogenesis along the animal-vegetal axis: fates of primary quartet micromere daughters in the gastropod Crepidula fornicata. [PDF]
, 2017 BackgroundThe Spiralia are a large, morphologically diverse group of protostomes (e.g. molluscs, annelids, nemerteans) that share a homologous mode of early development called spiral cleavage.

Folded gastrulation and T48 drive the evolution of coordinated mesoderm internalization in flies
eLife, 2016 Gastrulation constitutes a fundamental yet diverse morphogenetic process of metazoan development. Modes of gastrulation range from stochastic translocation of individual cells to coordinated infolding of an epithelial sheet.

Adhesive Crosstalk in Gastrulation [PDF]
Developmental Cell, 2003 Recent studies show that signaling through integrin receptors is required for normal cell movements during Xenopus gastrulation. Integrins function in this process by modulating the activity of cadherin adhesion molecules within tissues undergoing convergence and extension movements.

Retinoic Acid is Required for Normal Morphogenetic Movements During Gastrulation
Frontiers in Cell and Developmental Biology, 2022 Retinoic acid (RA) is a central regulatory signal that controls numerous developmental processes in vertebrate embryos. Although activation of Hox expression is considered one of the earliest functions of RA signaling in the embryo, there is evidence ...

Wnt5b integrates Fak1a to mediate gastrulation cell movements via Rac1 and Cdc42 [PDF]
Open Biology, 2020 Focal adhesion kinase (FAK) mediates vital cellular pathways during development. Despite its necessity, how FAK regulates and integrates with other signals during early embryogenesis remains poorly understood.
