Embryogenesis
Embryogenesis is the process by which the embryo is formed and develops, until it develops into a fetus.
Embryogenesis starts with the fertilization of the ovum (or egg) by sperm. The fertilized ovum is referred to as a zygote. The zygote undergoes rapid mitotic divisions with no significant growth (a process known as cleavage) and cellular differentiation, leading to development of an embryo.
Although embryogenesis occurs in both animal and plant development, this article addresses the common features among different animals, with some emphasis on the embryonic development of vertebrates and mammals.

Scientists uncover alternative pathway of microRNA generation
MicroRNAs are small bits of RNA within cells that wield enormous power. They influence virtually every biological process by controlling the "expression" of genes. Helping them in exerting this control is a unique class of ...

Glowing spirals: Chemical scaffolds guide living cells into precisely defined three-dimensional patterns
(PhysOrg.com) -- To find our way, we use maps. Cells use "chemical maps" to find the way: they orient themselves by following concentration gradients of attractants or repellants. David H. Gracias and a team ...
