Many Modes of Transport For an Embryo's Signals
Article Abstract:
The development of an embryo is a complex process, that is not yet completely understood. It has been thought that signaling molecules diffuse from their sources so that nearby cells are most affected. However, research is suggesting that the cells may send the signaling molecules to certain places, rather than making use of diffusion.

A fin-de-siecle achievement: charting new waters in vertebrate biology
Article Abstract:
Researchers have initiated a project to use genetic techniques to systematically analyze how the vertebrate embryo develops. They will analyze more than 1,800 developmental mutants to study how genetic defects affect the zebrafish embryo.

Article Abstract:
A new study shows that cholesterol is essential for directing a key molecule in embryogenesis. Cholesterol appears to regulate signalling of Hedgehog family of genes, which triggers bilateral division of the embryonic head.
