assistant
The three main cell types in the human body are epithelial, mesenchymal and hematopoietic. Epithelial cells line the surfaces of organs and other structures, such as skin, blood vessels, and digestive tract. Mesenchymal cells form the supportive framework of tissues and organs, providing structure and support for other cells. Hematopoietic cells produce red blood cells, white blood cells, and platelets.
