Options

A. Cells of the foetus skin
B. Mesenchymal pluripotent cells
C. Hematopoietic stem cells
D. All of the above

Answer

To solve the question "Which of the following can be obtained from amniotic fluid of the amniotic cavity that surrounds the developing fetus?", we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Amniotic Fluid**:
- Amniotic fluid is the liquid that surrounds and protects the developing fetus in the amniotic cavity. It plays a crucial role in fetal development, allowing movement and growth.

2. **Option Analysis**:
- **Option 1: Cells of the fetus skin**:
- Amniotic fluid contains fetal cells, including skin cells. These cells can be isolated for various tests and studies. Therefore, this option is correct.

- **Option 2: Mesenchymal pluripotent cells**:
- Mesenchymal stem cells, which are multipotent and can differentiate into various cell types, can also be found in amniotic fluid. This option is also correct.

- **Option 3: Hematopoietic stem cells**:
- Hematopoietic stem cells, responsible for the formation of blood cells, can be isolated from the fetal blood present in the amniotic fluid. Thus, this option is also correct.

- **Option 4: All of the above**:
- Since all the previous options (1, 2, and 3) are correct, this option is also correct.

3. **Conclusion**:
- The best answer to the question is **Option 4: All of the above**, as all the mentioned cell types can be obtained from the amniotic fluid surrounding the developing fetus.

### Final Answer:
**Option 4: All of the above**
