The role of Fibroblast Growth Factor 8 (FGF8) in embryonic development and organ formation is gaining increased recognition as scientists uncover its wide-ranging influence. FGF8, a powerful signaling ...

Biologists have provided new insights on a longstanding puzzle in biology: How complex organisms arise from a single fertilized cell. Producing a new 'gene atlas' with 4-D imaging, the researchers ...

Understanding the mechanisms of early human embryogenesis is pivotal for addressing global health challenges — from infertility and congenital defects to adult diseases rooted in developmental ...

Finally, mosaic aneuploidy has also been observed in cell culture where there is less negative selection against such cells, demonstrating the context dependence of the consequences of mosaicism. For ...

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

A new review from Genes and Diseases sheds light on the pivotal role of LINE-1 elements in preimplantation development and totipotency, revealing their essential contributions to early mammalian ...

Bioengineering researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a soft, thin, stretchable bioelectronic device that can be implanted into a ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development—including the production ...
