Some differentiated cells become senescent almost immediately, leaving the cell cycle and undergoing terminal differentiation. Other cells have a high need to proliferate in order to grow and repair the organ or tissue, so they do not enter senescence for a long period of time. Which cell type would be most likely to put off senescence and terminal differentiation so it could continue to replicate in order to grow and repair?
brain cells
skin cells
heart cells
lung cells

Skin cells.
Epithelial cells of the skin routinely divide to replace damaged or shed cells, so they delay senescence and remain capable of proliferation for wound repair and growth. By contrast, most brain neurons and cardiac muscle cells are largely post‑mitotic (terminally differentiated), and lung cells have more limited regenerative capacity than skin.
