- Keratinocytes are the predominant cell type found in the epidermal layer. Knowing that manyof these cells die each day while an equal number are produced, you are interested inunderstanding where they come from and how the population is maintained.a) You collect a sample of keratinocytes and allow them to grow in cell culture. Thoughthe cells are visibly indistinguishable from each other, you find that some fail to dividewhile others have formed large colonies. What might be different about the two typesof cells?b) You take all the cells from one of the large colonies and grow them on a fresh plate.You see some of the cells again form large colonies, but most fail to divide.
