This paper describes how the vertebrate version of the hedgehog gene-as expressed by the notochord (an embryonic structure)-induces the formation of floor plate cells and motor neurons in the ...

Embark on an exciting journey of discovery with our in-school enrichment program, 4-H Embryology in the Classroom! Designed for pre-K through high school teachers, this immersive experience brings the ...

Embryology is the discipline concerned with the study of embryogenesis, the development of the embryo from a fertilised egg cell. Findings in embryology have helped in the understanding of ...

Scientists have developed human stem cell models containing the notochord, a critical tissue that guides spine and nervous system formation during embryonic development. Using precise chemical signals ...

Feb. 10, 2025 — Evolution is traditionally associated with a process of increasing complexity and gaining new genes. However, the explosion of the genomic era shows that gene loss and ...

28, 2025 — A team of stem cell scientists have successfully used embryonic stem cell engineering ... human stem cell models which contain notochord -- a tissue in the developing embryo that ...

The diversity of regenerative phenomena seen in adult metazoans, as well as their underlying mechanistic bases, are still far from being comprehensively understood. Reviewing both ultrastructural and ...

This study convincingly shows that aquaporin-mediated cell migration plays a key role in blood vessel formation during zebrafish development. In particular, the article implicates hydrostatic pressure ...

The ability of cells to alter their phenotypic and morphological characteristics, known as cellular plasticity, is critical in normal embryonic development and adult tissue repair and contributes to ...

This important study examines the role of pericytes in patterning the zebrafish blood-brain barrier (BBB) and controlling its permeability. Using pdgfrb mutant zebrafish models lacking brain pericytes ...

Embryonic stem cells and induced pluripotent stem cells are pluripotent stem cells. Comparative analysis of 100+ PSC lines highlights biological differences between defined and undefined culture ...

A team of stem cell scientists have successfully used embryonic stem cell engineering to create a bi-paternal mouse—a mouse with two male parents—that lived until adulthood. Their results ...
