Cellular Differentiation

Cellular differentiation is the process when a less specialized cell become a more specialized cell type. Cell differentiation happens many times when a multicellular organism is developing, it changes from a single zygote to a complex system of tissues and cell types. Cellular differentiation is also common in adult stem cells divide and create fully differentiated  daughter cells while the tissue repairs and while a normal cell turnover. Cell differentiation changes a cells size, shape, membrane potential, metabolic activity, and responsiveness to signals.

Steps:

1) Zygote 

2)Blastocyst

3)Gastrula

Germ Layers:

1) Mesoderm - Cardiac Muscle, Skeletal Muscle cells, Tubule cell so the kidney, Red blood cells, Smooth muscle

2)Endoderm - Lung cell, thyriod cell, pancreatic cell
