Somatic cell cycle consists of four phases while early embryonic cell cycle alternates between S and M phases without intervening G1 and G2 phases. Different models of cell cycle regulation ...

In this slide show showing somatic cell nuclear transfer ... that stimulates cellular division. The first division results in two cells (left image), the next makes four cells, and so on.

These issues are largely resolved by using iPS stems cells that arise from somatic cells because they can be recovered from an adult source. Furthermore, if cells are recovered from a human donor ...

The adult worm consists of 959 somatic cells that arise via an invariant cell lineage ... fate differentiaiton creates small but reproducible differences in division timing among cells that would ...
