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.
الخلايا الجذعية: نظرة عامة
Stem cells are undifferentiated cells characterized by their pluripotency, مما يعني أن لديهم القدرة على التطور إلى أي نوع من الخلايا في الجسم. 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 (التجديد الذاتي), maintaining a pool of undifferentiated cells.
- التمايز: Stem cells can differentiate into specialized cell types, such as neurons, muscle cells, أو خلايا الدم, a process known as lineage commitment. This ability allows them to contribute to the growth, بصلح, and regeneration of tissues.
