Gastrula‐Premarked Posterior Enhancer Primes Posterior Tissue Development Through Cross‐Talk with TGF‐β Signaling Pathway

open access: yesAdvanced Science, Volume 12, Issue 36, September 25, 2025.
A gastrula‐premarked enhancer within the first intron of Cdx2 governs posterior embryonic development via both regulating Cdx2 expression in cis and coordinating TGF‐β signaling in trans to ensure proper posterior body development. Functional rescue in gastruloids reveals a Cdx2‐independent pathway, highlighting p‐Enh‐eRNA as key epigenetic ...

X-chromosome inactivation mosaicism in the three germ layers and the germ line of the mouse embryo [PDF]

open access: yes, 1982
Electrophoretic variant forms of the X-linked enzyme phosphoglycerate kinase (PGK-1, E.C.2, 7, 2, 3) have been used to examine X-chromosome mosaicism in tissues from 121/2-day post coitum heterozygous female mouse embryos.

Large‐Scale Bioprinting of Human Epiblast‐Like Models Featuring Disc‐Shaped Morphogenesis and Gastrulation Events

open access: yesAdvanced Science, Volume 12, Issue 33, September 4, 2025.
Large‐scale generation of disc‐shaped models mimicking human epiblast layer is achieved by bioprinting of human pluripotent stem cells using a well‐defined biomatrix. The bioactive component and physical confinement from laminin/alginate microgels, combined with the endogenous regulation of the WNT signaling pathway regulated disc‐like morphogenesis ...

Conceptus signals for establishment and maintenance of pregnancy

open access: yesReproductive Biology and Endocrinology, 2004
Establishment and maintenance of pregnancy results from signaling by the conceptus (embryo/fetus and associated extraembryonic membranes) and requires progesterone produced by the corpus luteum (CL).

Reduced Offspring Viability Is Associated With Long‐Term Stability of a Narrow Avian Hybrid Zone

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
We investigated hybrid viability in a tropical, avian hybrid zone governed by strong selection on male secondary sexual traits between the white‐collared manakin (Manacus candei) and golden‐collared manakin (M. vitellinus). We assessed putative hybrid fitness by investigating adult survival and hatching success along with a prospective selective ...

Polydactylous limbs in Strong's Luxoid mice result from ectopic polarizing activity [PDF]

open access: yes, 1995
Strong's Luxoid (1st^D) is a semidominant mouse mutation in which heterozygotes show preaxial hindlimb polydactyly, and homozygotes show fore- and hindlimb polydactyly.

Spatiotemporal Expression of Pregnancy-Specific Glycoprotein Gene rnCGMl in Rat Placenta [PDF]

open access: yes, 1993
As a basis towards a better understanding of the role of the pregnancy-specific glycoprotein (PSG) family in the maintenance of pregnancy, detailed investigations are described on the expression of a recently identified rat PSG gene (rnCGM1) at the mRNA ...

Development of node architecture and emergence of molecular organizer characteristics in the pig embryo

open access: yesDevelopmental Dynamics, Volume 254, Issue 8, Page 916-934, August 2025.
Abstract Background The avian node is the equivalent of the amphibian Spemann's organizer, as indicated by its ability to induce a secondary axis, cellular contribution, and gene expression, whereas the node of the mouse, which displays limited inductive capacities, was suggested to be a part of spatially distributed signaling.

A network of transient domains for breaking symmetry during anterior–posterior axis formation in the porcine embryo

open access: yesDevelopmental 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 ...
