How do cells differentiate in multicellular organisms?

What factors influence cell differentiation?
Environmental factors can also influence gene expression and cell differentiation. For example, available nutrients, salinity, and temperature are all factors that can influence gene expression in organisms. In Himalayan rabbits, genes that code for fur color are turned on and off depending on temperature.
