1·Stem cells are immature cells that give rise to multiple cell types, while also replenishing themselves through a process of self-renewal.

干细胞是不成熟的细胞，可以分化成多种多样的细胞类型，在自我更新的过程中，它们也会自我补充。

2·There is hope that damage to the spinal cord and brain will one day be treatable using stem cells (i. e. immature cells that can develop into different cell types).
