Question

stem cells are seen in adult human or any animals?

Answer 1

HEYA MATE,

HERE IS UR ANSWER.

Thanks for asking this question.

First, let’s redefine the question to ask how many tissue progenitor cells are there in the adult body. Depending upon tissue type, this can range from as high as 5% to less than 1%. With age, this number can decrease. The precise number would depend upon how many cells there are in the body.

Second, I think the important underlying question is, with so many millions of stem/progenitor cells, why do we suffer from degenerative illnesses or fail to replace many tissues?

I don’t have the answer, as this is an active topic of research for 100’s of teams all over the world.

I HOPE IT HELPS YOU.
