Among the following stem , cell which are found in umbilical cord:

Options

A. Embryonic stem cells
B. Adult stem cells
C. Cord blood stem cells
D. All of the above

Answer

### Step-by-Step Solution:

1. **Understanding Stem Cells**:
- Stem cells are unique cells that have the ability to divide and differentiate into various types of cells throughout their lifetime. They are classified into different types based on their origin and potential.

2. **Types of Stem Cells**:
- **Embryonic Stem Cells**: These stem cells are derived from embryos and have the potential to differentiate into any cell type. However, they are not found in the umbilical cord.
- **Adult Stem Cells**: These are obtained from adult tissues and can differentiate into a limited range of cell types specific to the tissue they originate from. They are not found in the umbilical cord either.

3. **Umbilical Cord Stem Cells**:
- The stem cells that are specifically found in the umbilical cord are known as **cord blood stem cells**. These cells are collected from the blood of the umbilical cord and placenta after childbirth.

4. **Function and Applications**:
- Cord blood stem cells have the ability to differentiate into various types of blood cells and are used in medical treatments, particularly for conditions like leukemia and anemia. They can help replace damaged or diseased cells in the body.

5. **Conclusion**:
- Therefore, the correct answer to the question regarding which stem cells are found in the umbilical cord is **cord blood stem cells**.

### Final Answer:
- The type of stem cells found in the umbilical cord is **cord blood stem cells**.
