A recombinant protein recommended to patients on kideney dialysis is :

Options

A. calcitonin
B. Interferon
C. erythropoietin
D. platelet derived growth factor

Answer

To solve the question regarding which recombinant protein is recommended to patients on kidney dialysis, we can follow these steps:

### Step 1: Understand the context of kidney dialysis
Kidney dialysis is a treatment for patients whose kidneys are not functioning properly. It helps to remove waste products and excess fluid from the blood when the kidneys can no longer do so.

### Step 2: Identify the role of hormones produced by the kidneys
The kidneys produce several important hormones, one of which is erythropoietin (EPO). EPO is crucial for the production of red blood cells in the bone marrow.

### Step 3: Evaluate the options provided
1. **Calcitonin**: This hormone regulates calcium and phosphate levels but is not directly related to kidney function.
2. **Interferon**: This protein is involved in immune response but does not have a direct role in kidney function or dialysis.
3. **Erythropoietin**: This hormone is produced by the kidneys and stimulates the production of red blood cells, which is vital for patients undergoing dialysis as they often suffer from anemia.
4. **Platelet-derived growth factor**: This is involved in healing and growth but is not specifically related to kidney function.

### Step 4: Determine the correct answer
Given the roles of these proteins, the recombinant protein that is specifically recommended for patients on kidney dialysis is **Erythropoietin**.

### Final Answer
The recombinant protein recommended to patients on kidney dialysis is **Erythropoietin**.
