During the process of embryogenesis, formation of multiple cell types from stem cells occurs due to differentiation. In developmental biology, cellular differentiation is the process of a cell changing from one cell type to another. Most commonly this is a less specialized type becoming a more specialized type, such as during cell growth. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types.
