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 ...
