Which hormone is cited as promoting cell growth and differentiation?

• A. Apoptosis
• B. Necrosis
• C. Hormones like erythropoietin promote cell growth and differentiation.
• D. Autophagy

Answer: (C)

Hormones regulate cell growth and differentiation. Erythropoietin is a hormone that acts on erythroid progenitors in the bone marrow, binding to its receptor and triggering signaling pathways that promote their survival, proliferation, and maturation into red blood cells. This makes it a classic example of a hormone that drives both growth and differentiation of a specific cell lineage. The other terms describe processes that do not promote growth or maturation: apoptosis and necrosis are forms of cell death, while autophagy is a cellular recycling/survival process that can support maintenance under stress but does not directly promote new cell growth or differentiation.
