During the first 72 hours in particular, extracellular vesicles—nanoparticles enclosed in cell membranes—play a significant role in the embryonic development of zebrafish. This is the result of a ...

Tiny, striped zebrafish are helping scientists trace how a gene linked to albinism influences eye development, work that may ...

RIKEN researchers have determined the molecular structure of an enzyme that occurs in fish. This could shed light on molecular processes in a wide range of marine organisms. The work is published in ...

Embedded within the mammalian life cycle is a highly organised progression from fertilisation through preimplantation stages, blastocyst formation, implantation and subsequent axis establishment and ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...
