Cell regulation/death

... body (e.g. making fingers on fetus), that process requires programmed cell death. The mammalian cells require growth hormones and other signals to proliferate and live. If they lack them, or they receive signal to die off, they undergo the PCD. The telomeres are problem, but they measure for all ...

Re: Beneficial mutations vs harmful

... are actually destructive, they just happen to help in that particular environment (eg. sickle cell anemia). Neutral mutations may or may not be proliferated as they have no beneficial or disadvantageous aspect. In the face of so much destruction, how can occasional beneficial/constructive mutations ...

Re: adult stem cells, differentiated cells and proliferation

... except gametes and their precursors. As to your second set of questions if you are talking about replicating, then yes differentiated cells do proliferate in vivo, generally via mitosis. Cancerous cells proliferate excessively, with no control from the cell cycle. Due to these facts stem cells ...

adult stem cells, differentiated cells and proliferation

hi, I have two questions: 1) Are adult stem cells somatic cells? 2) Can differentiated cells proliferate in vivo? I mean once blood cells, nerve cells, muscle cells are differentiated do they actually proliferate if they are not cancerous? Or can only stem cells proliferate? ...

Life seems to have this very powerful urge to proliferate, with every species breeding to capacity. Why is this so? What is it that made this drive? And it isn't only sentient objects that have it. It's a universal law. I ask this very question ...
