While all life begins as a single cell, the human body is not just one cell type. Cells that can divide without becoming a specific cell type (e.g. skin cells) are known as (Click to select). 3. When stem cells undergo mitosis and divide, they produce two cells. One cell remains a stem cell and the other is a partially specialized cell known as a (Click to select) cell. 4. Cells undergo a process of specialization or determination called (Click to select) to become neurons, muscle cells, or skin cells. Stem cells are the source of all different cell types.
