Stem cells are cells that have the remarkable potential to develop into many different cell types in the body. Serving as a sort of repair system for the body, they can theoretically divide without limit to replenish（补充）other cells for as long as the person or animal is still alive. When a stem cell divides, each daughter cell has the potential to either remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell. 跨楚谷金睫蓖拴台捆管雪离轿墙宵柄晴养喊钮砂免搀净利胡侯眉郊疏眩裁Unit 12 Stem-Cell Rebels课件Unit 12 Stem-Cell Rebels课件 What classes of ste
