Final answer:
Granulocyte colony-stimulating factor (G-CSF) is a glycoprotein hormone that stimulates the differentiation of myeloblasts into granular leukocytes. It is used to increase white blood cell counts in cancer patients undergoing chemotherapy.
Step-by-step explanation:
Granulocyte colony-stimulating factor (G-CSF) is a type of glycoprotein hormone known as a colony-stimulating factor (CSF). CSFs are responsible for triggering the proliferation and differentiation of specific cells in the body. G-CSF specifically stimulates the differentiation of myeloblasts into granular leukocytes, including neutrophils, eosinophils, and basophils.
It is used in medicine to increase white blood cell counts in patients with certain forms of cancer who are undergoing chemotherapy.
