Embryonic stem cells derived from the inner cell mass are described as:
Select the correct option:
Solution
Incorrect! Answer:
Pluripotent
- Source: Embryonic stem cells (ESCs) are obtained from the inner cell mass of a blastocyst-stage embryo.
- Potency Defined:
- Totipotent: Can form every cell type in the body PLUS extra-embryonic tissues like the placenta (e.g., zygote).
- Pluripotent: Can form any cell type of the three germ layers (ectoderm, mesoderm, endoderm) that make up the body, but cannot form the placenta independently.
- Multipotent: Can differentiate into several closely related cell types (e.g., hematopoietic stem cells).
- Result: ESCs are considered pluripotent, making them highly valuable for regenerative medicine.
