Question

Is the following statement true? Explain your answer.
'Every tissue that can be renewed is renewed from a tissue-specific population of stem cells. '

Answer 1

True statement

Tissue renewal is determined by the rate of cell division.This process of renewal has a starting point of stem cells, located in a specific environment called the 'niche'.Stem cells proliferation and differentiation can be coordinated with the death of cells that needs to be replaced.Other processes such as cell migration, epigenetics and cellular communications are also necessary for cell renewal.Fast tissue renewal can be recognized by a higher mitotic activity and slower renewal tissues contains lesser mitosis and may not be easily recognized by non- renewing areas.The fate decision of stem cells during proliferation directly influence tissue renewal and homeostasis.
