In mammals, the fusion of sperm and oocyte gives rise to a totipotent zygote, which undergoes a series of cleavage divisions and differentiation events. During this process, the embryo transitions ...

In July 1932, young pathology resident Elizabeth M. Ramsey was performing a routine autopsy with a colleague at New Haven Hospital when she made an extraordinary discovery: an apparently normal human ...

Studying the shape of tissues and organs is critical to understanding how they are formed. Embryonic development happens in three dimensions, but many studies are limited by the use of two-dimensional ...

Successful fertility treatments, including in vitro fertilization (IVF), is often reliant on a clear understanding of developmental stages of human development. Clinicians working with assisted ...

Mammalian early embryonic development is regulated by numerous factors, yet not all have been identified. Although omics approaches such as next-generation sequencing and proteomics provide powerful ...

Every human life begins as a cluster of cells that soon face critical decisions. Within weeks, those cells must choose their fates – some forming the nervous system, others the gut, heart, or muscle.
