Which epidermis layer includes stem cells that continually undergo cell division?
The Stratum basale (Stratum germinativum)
Mitotic cell division occurs in the Basale layer of the epidermis. Stem cells undergo mitosis to produce new keratinocytes. Of the two keratinocyte daughter cells produced by mitosis, one migrates to the surface of your skin while the one remains in the basale layer of the epidermis to produce more keratinocytes cells.
Yes, ALL cells undergo cell division. Because if there were types of cells that don't undergo cell division, these cells' specialization wouldn't be able to grow or be replaced. For example if hair cells didn't undergo cell division; your hair wouldn't be able to grow. NO!! Nerve cells,Red blood cells..they don't undergo cell division.
