Ectopic Expression of T‐Box Transcription Factors Alters Mouse Forelimb Formation
genesis, Volume 64, Issue 2, April 2026.ABSTRACT The developing vertebrate forelimb expresses seven T‐box transcription factors, with several in overlapping expression domains. All T‐box transcription family members share similarity within their DNA binding domain, the T‐domain. Outside of the T‐domain, these factors share little similarity, allowing family members to have different ...

The transcription factor Pitx2 positions the embryonic axis and regulates twinning
eLife, 2014 Embryonic polarity of invertebrates, amphibians and fish is specified largely by maternal determinants, which fixes cell fates early in development. In contrast, amniote embryos remain plastic and can form multiple individuals until gastrulation.

Gastrulation in the sea urchin
, 2020 Gastrulation is arguably the most important evolutionary innovation in the animal kingdom. This process provides the basic embryonic architecture, an inner layer separated from an outer layer, from which all animal forms arise. An extraordinarily simple and elegant process of gastrulation is observed in the sea urchin embryo. The cells participating in

Interplay between bone morphogenetic proteins and cognate binding proteins in bone and cartilage development: noggin, chordin and DAN. [PDF]
, 2001 This commentary is a concise discussion of the interactions between bone morphogenetic proteins (BMPs) and their binding proteins in bone and cartilage morphogenesis.

Ecology and Evolution, Volume 16, Issue 4, April 2026.The two color morphs of the Iberian–Atlantic Paramuricea complex show little genetic divergence, and their species boundaries have remained unclear. By analyzing gametogenesis, spawning timing, fertilization environment, and early life‐history traits, we reveal strong prezygotic barriers and divergent developmental and dispersal strategies between the ...

Post‐Oviposition Embryonic Staging Scheme for the Delicate Skink, Lampropholis delicata
Journal of Morphology, Volume 287, Issue 4, April 2026.We detail the morphology of post‐oviposition embryos throughout development and compare it with reptilian embryonic staging schemes from other squamates. We identified 16 embryo stages based on the development of limbs, eyes, brain, branchial arches, frontonasal prominence, otic vesicle, scales, and pigmentation.

eLife, 2019 In mouse embryo gastrulation, epiblast cells delaminate at the primitive streak to form mesoderm and definitive endoderm, through an epithelial-mesenchymal transition.

Intercellular Bridges in Vertebrate Gastrulation
PLoS ONE, 2011 The developing zebrafish embryo has been the subject of many studies of regional patterning, stereotypical cell movements and changes in cell shape. To better study the morphological features of cells during gastrulation, we generated mosaic embryos expressing membrane attached Dendra2 to highlight cellular boundaries.

The Homeobox Genes: Classification, Regulation, Biological Functions, and Diseases
MedComm, Volume 7, Issue 4, April 2026.Overview of the homeobox gene superfamily and its pathophysiological roles. The homeobox superfamily comprises several major classes, including ANTP, PRD, TALE, LIM, POU, and others. Among these, the HOX clusters (A–D) play critical roles in embryonic development specifically in conferring cellular identity, regulating morphogenesis, and guiding axial ...
