Peripheral blood stem cell harvesting is a procedure that collects stem cells from a person's blood. Here is a step-by-step explanation of how growth factors are administered in this process:

1. **Preparation**: Before the harvesting process begins, the patient usually undergoes a series of tests to ensure they are healthy enough for the procedure. This includes blood tests, physical examinations, and sometimes imaging studies.

2. **Administration of Growth Factors**: Growth factors are proteins that stimulate the bone marrow to produce more blood cells. In this case, a growth factor called Granulocyte Colony Stimulating Factor (G-CSF) is commonly used. This is administered through injections, usually once daily, for several days before the harvesting procedure. The G-CSF stimulates the bone marrow to produce more stem cells and helps push them out into the bloodstream.

3. **Monitoring**: After the growth factors are administered, the patient's blood is regularly monitored to check the number of stem cells present. This is usually done through a simple blood test.

4. **Harvesting**: Once the number of stem cells in the blood has increased sufficiently, the harvesting process can begin. This involves drawing blood from the patient, passing it through a machine that separates out the stem cells, and then returning the rest of the blood back to the patient.

5. **Post-Harvesting**: After the stem cells have been collected, they can be used immediately for a transplant, or they can be frozen and stored for future use.

6. **Follow-Up**: The patient will have regular follow-up appointments to monitor their recovery and to check the success of the transplant if one was performed.

Remember, this is a general overview and the exact process can vary depending on the individual patient's condition and the specific protocols of the medical facility.
