Stem cells are remarkable cells that hold immense potential in the field of regenerative medicine. Their unique ability to self-renew and differentiate into various specialized cell types has sparked significant interest in their therapeutic applications.
干细胞: 概述
Stem cells are undifferentiated cells characterized by their pluripotency, 意味着它们有可能发展成体内任何类型的细胞. This remarkable ability makes them a valuable resource for repairing damaged tissues, replacing lost cells, and potentially treating a wide range of diseases.
Stem Cell Definition and Characteristics
Stem cells are defined by their two primary characteristics:
- 自我更新: Stem cells have the capacity to divide and generate identical daughter cells (自我更新), maintaining a pool of undifferentiated cells.
- 分化: Stem cells can differentiate into specialized cell types, 例如神经元, 肌肉细胞, 或血细胞, a process known as lineage commitment. This ability allows them to contribute to the growth, 维修, 和组织的再生.
