Re: adult stem cells, differentiated cells and proliferation

... organism. Adult stem cells however have lost some of their potency and are Pluripotent- They can only differentiate into the three germ layers, Ectoderm, mesoderm (if present) and Endoderm. I suggest you look up the Cell cycle as it will help you understand somatic cell replication and cancerous ...

Cells positioning

... as by specific apoptosis patterns and up-/downregulation of developmental gene regions. One crucial feature is the formation of the cell layers ectoderm, endoterm and mesoterm, which eventually develop into organs and other body parts by very specific events of cleavage, splitting, folding and ...
