Key Points
Types of Stem Cells:
Embryonic Stem Cells (ESCs): Derived from early-stage embryos, these cells can differentiate into all cell types.
Adult Stem Cells: Found in various tissues, they are more limited in their differentiation potential.
Induced Pluripotent Stem Cells (iPSCs): Adult cells reprogrammed to an embryonic-like state, offering versatility without the ethical concerns of ESCs.
Applications:
Stem cells are used in treating conditions like leukemia, spinal cord injuries, and degenerative diseases. Research is ongoing to expand their therapeutic uses.
Additional Insight
Recent advancements have led to the development of iPSCs, which are adult cells reprogrammed to an embryonic-like state. This breakthrough allows for patient-specific therapies, reducing the risk of immune rejection and sidestepping ethical issues associated with embryonic stem cells.
