How do human cells specialize into different types like muscle or neuron?
Quick Answer
Cells specialize by activating different genes and silencing others. This process is called differentiation.
The Full Story
A developing human starts with cells that can give rise to many different tissue types. As development proceeds, signals from the environment and neighboring cells tell them which genes to activate. Muscle cells turn on genes for contraction, neurons turn on genes for signaling, and skin cells turn on genes for barrier formation. Differentiation is what makes one genome able to produce such a wide range of cell types.
