Formin isoforms are differentially expressed in the mouse embryo and are required for normal expression of fgf-4 and shh in the limb bud [PDF]
, 1995 Mice homozygous for the recessive limb deformity (ld) mutation display both limb and renal defects. The limb defects, oligodactyly and syndactyly, have been traced to improper differentiation of the apical ectodermal ridge (AER) and shortening of the ...

Cell death and morphogenesis during early mouse development: Are they interconnected? [PDF]
, 2015 Shortly after implantation the embryonic lineage transforms from a coherent ball of cells into polarized cup shaped epithelium. Recently we elucidated a previously unknown apoptosis‐independent morphogenic event that reorganizes the pluripotent lineage ...

Developmental Dynamics, Volume 254, Issue 8, Page 902-915, August 2025.Abstract Breaking radial symmetry for anterior–posterior axis formation is one of the key developmental steps of vertebrate gastrulation and is established through a succession of transient domains defined by morphology or gene expression. Three such domains were interpreted recently in the rabbit to be part of a “three‐anchor‐point model” for axis ...

Macrophages: Subtypes, Distribution, Polarization, Immunomodulatory Functions, and Therapeutics
MedComm, Volume 6, Issue 8, August 2025.Macrophages originate from the yolk sac, fetal liver, and bone marrow, differentiating into two main subtypes: M1‐like (proinflammatory) and M2‐like (anti‐inflammatory). These subtypes exhibit high plasticity, allowing them to transform in response to environmental cues or therapeutic interventions.

Inactivation of Drosophila Huntingtin affects long-term adult functioning and the pathogenesis of a Huntington’s disease model [PDF]
, 2008 A polyglutamine expansion in the huntingtin (HTT) gene causes neurodegeneration in Huntington’s disease (HD), but the in vivo function of the native protein (Htt) is largely unknown. Numerous biochemical and in vitro studies have suggested a role for Htt

Function of Bmpr1a in ES cell differentiation and cell competition [PDF]
, 2010 Bone morphogenetic protein (BMP) 4 signalling via BMPR1A is required for the maintenance of the epiblast in the early embryo, and for self-renewal of pluripotent mouse embryonic stem (ES) cells by inhibiting neural differentiation.

Cellular aspect ratio and cell division mechanics underlie the patterning of cell progeny in diverse mammalian epithelia. [PDF]
, 2018 Cell division is essential to expand, shape, and replenish epithelia. In the adult small intestine, cells from a common progenitor intermix with other lineages, whereas cell progeny in many other epithelia form contiguous patches.

The transcription factor GATA6 is essential for early extraembryonic development [PDF]
, 1999 The gene coding for the murine transcription factor GATA6 was inactivated by insertion of a beta-galactosidase marker gene. The analysis of heterozygote GATA6/lacZ mice shows two inductions of GATA6 expression early in ...

Prospects for transgenesis in the chick [PDF]
, 2004 Research to develop a useful method for genetic modification of the chick has been on-going since the first demonstrations in the mouse in the 1980s that genetic modification is an invaluable tool for the study of gene function. Manipulation of the chick

Vital dye labelling demonstrates a sacral neural crest contribution to the enteric nervous system of chick and mouse embryos [PDF]
, 1991 We have used the vital dye, DiI, to analyze the contribution of sacral neural crest cells to the enteric nervous system in chick and mouse embryos. In order to label premigratory sacral neural crest cells selectively, DiI was injected into the lumen of ...
