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, meaning they have the potential to develop into any type of cell in the body. 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:
- Self-Renewal: Stem cells have the capacity to divide and generate identical daughter cells (自我更新), maintaining a pool of undifferentiated cells.
- 差异化: Stem cells can differentiate into specialized cell types, 比如神经元, 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, and regeneration of tissues.
