Distinct modes of floor plate induction in the chick embryo [PDF]
, 2003 To begin to reconcile models of floor plate formation in the vertebrate neural tube, we have performed experiments aimed at understanding the development of the early floor plate in the chick embryo. Using real-time analyses of cell behaviour, we provide

Periodontology 2000, EarlyView.Abstract Orthodontic therapy applies forces to teeth, causing an inflammatory reaction in the periodontal ligament. This is repaired by remodeling of the periodontium, allowing tooth displacement. Although orthodontic therapy is mostly initiated during childhood and adolescence, the number of adults seeking this treatment is increasing as our society's

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

TFAP2C regulates transcription in human naive pluripotency by opening enhancers. [PDF]
, 2018 Naive and primed pluripotent human embryonic stem cells bear transcriptional similarity to pre- and post-implantation epiblast and thus constitute a developmental model for understanding the pluripotent stages in human embryo development. To identify new

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

The RNA Helicase DDX6 Controls Cellular Plasticity by Modulating P-Body Homeostasis [PDF]
, 2019 Post-transcriptional mechanisms have the potential to influence complex changes in gene expression, yet their role in cell fate transitions remains largely unexplored.

Regulating Retinoic Acid Availability during Development and Regeneration: The Role of the CYP26 Enzymes. [PDF]
, 2020 This review focuses on the role of the Cytochrome p450 subfamily 26 (CYP26) retinoic acid (RA) degrading enzymes during development and regeneration. Cyp26 enzymes, along with retinoic acid synthesising enzymes, are absolutely required for RA homeostasis

Germ cell and other tumors in individuals with differences in sex development
CA: A Cancer Journal for Clinicians, Volume 75, Issue 6, Page 587-601, November/December 2025.Abstract Approximately one in 3500 to one in 5100 live‐born infants have atypical external genital development, known as differences in sex development (DSD). In 2005, an expert consensus conference thoroughly reviewed aspects of health care for individuals with DSD.

NANOG is required to form the epiblast and maintain pluripotency in the bovine embryo
Molecular Reproduction and Development, 2019 During preimplantation development, the embryo undergoes two consecutive lineages specifications. The first cell fate decision determines which cells give rise to the trophectoderm (TE) and the inner cell mass (ICM).
