Researchers have developed a cell culture system that differentiates human pluripotent stem cells to amniotic and surface ectoderm, which are essential for human embryo development. The study found that the degree of cell crowding influences cell identity decision.
Researchers developed a self-organizing system that models key cellular processes involved in embryogenesis, shedding light on the self-organization of ectodermal cells during neurulation. The study could inform ways to prevent or counteract central nervous system birth defects by optimizing human ectodermal development.
Researchers identified the molecular mechanism underlying Weiss-Kruszka syndrome, a rare neurodevelopmental disorder characterized by craniofacial anomalies and autistic features. The study reveals that the ZFP462 gene mutation leads to a failure to safeguard neural lineage specification during early embryonic development.
Researchers discovered YAP1 is a master regulator of Nodal signaling in human embryonic stem cells, crucial for human development. The study found that YAP1 regulates the allocation of germ layers and dictates the production of Nodal protein, essential for gastrulation.

Researchers at University College London discovered that embryonic cells can navigate towards harder regions using chemical and mechanical signals, guiding the formation of facial features. This breakthrough could help prevent birth defects and infant mortality by improving understanding of cell migration mechanisms.
A team of researchers has found a new connection between physical forces and limb development in embryos, using live imaging and computer models. Their study could lead to simulations that help repair deformed limbs, potentially creating a drug to alter mechanical stress on cells.
Researchers discovered Sonic hedgehog gene presence in ectoderm of mice limb buds, indicating a new role in digit formation and possible implications for human birth defects. Disrupting this signaling led to extra digits forming.
