The fibres that form an interconnecting network are secreted by 

Options

A. fibrocytes
B. reticulocyte
C. endothelium
D. reticular cells

Answer

To answer the question "The fibres that form an interconnecting network are secreted by," we need to analyze each of the given options step by step.

### Step-by-Step Solution:

1. **Understanding Fibrocytes**:
- Fibrocytes are cells involved in the production of collagen and vimentin. They play a role in the formation of connective tissue but do not specifically produce the interconnecting network of fibers.
- **Conclusion**: Fibrocytes do not secrete the fibers that form an interconnecting network.

2. **Understanding Reticulocytes**:
- Reticulocytes are immature red blood cells (erythrocytes). They are involved in the maturation process of red blood cells and do not contribute to the formation of connective tissue or interconnecting fibers.
- **Conclusion**: Reticulocytes do not secrete the fibers that form an interconnecting network.

3. **Understanding Endothelium**:
- Endothelium is a layer of cells that lines blood vessels. It is composed of endothelial cells and is primarily involved in the regulation of blood flow and barrier functions, not in forming an interconnecting network of fibers.
- **Conclusion**: Endothelium does not secrete the fibers that form an interconnecting network.

4. **Understanding Reticular Cells**:
- Reticular cells are a type of fibroblast that specifically contribute to the formation of reticular fibers. These fibers create a thin, interconnecting network that provides structural support in various tissues, particularly in lymphoid organs.
- **Conclusion**: Reticular cells are responsible for secreting the fibers that form an interconnecting network.

### Final Answer:
The correct answer is **reticular cells**.
