Stem cells are undifferentiated cells that have the ability to continue to grow and divide in their nonspecialized state for long periods of time (e. g., months or years).

A.
mutations in their genetic code.
B.
meiotic division and fertilization.
C.
different patterns in their gene expression.
D.
random segregation and proliferation.
