As unspecialized cells mature, what controls their development into specific cell types?

The age of neighboring cells

The rate at which the cells grow

The genes expressed within the cells

The nutrients available to the cells

1 answer

The primary factor that controls the development of unspecialized cells into specific cell types is the genes expressed within the cells. During differentiation, specific genes are turned on or off, leading to the production of proteins that determine the characteristics and functions of the matured cells. While neighboring cells, growth rates, and available nutrients can influence cell development, it is ultimately the genetic expression that directs the process of differentiation into specific cell types.
