Questions and Answers
What role do differentiation inducers play in stem cell development?
What role do differentiation inducers play in stem cell development?
- They stimulate the growth of all stem cells.
- They prevent stem cells from differentiating.
- They assist in the transformation of committed stem cells into adult blood cells. (correct)
- They trigger the apoptosis of stem cells.
How is the formation of growth inducers and differentiation inducers regulated?
How is the formation of growth inducers and differentiation inducers regulated?
- They have no external regulation.
- Their regulation occurs outside the bone marrow. (correct)
- They are directly influenced by stem cell types.
- They are controlled within the bone marrow.

What hormone is responsible for stimulating erythropoiesis in response to low blood oxygen levels?
- Vascular endothelial growth factor
- Erythropoietin (EPO) (correct)
- Cytokine
- Hemoglobin

Differentiation Inducers
Chemicals that cause committed stem cells to change into specialized adult cells.
RBC Production Control
RBC Production Control

Study Notes
Stem Cell Growth and Differentiation
- Stem cell growth and reproduction are controlled by proteins called growth inducers (e.g., interleukin-3)
- Differentiation inducers cause committed stem cells to mature into adult blood cells.
- Differentiation involves multiple steps leading to specialized blood cells.
Regulation of RBC Production
- RBC production (erythropoiesis) is regulated by factors outside the bone marrow.
- Exposure to low oxygen levels triggers growth induction, differentiation, and increased RBC production.
- Erythropoietin, a hormone produced by the kidneys, stimulates erythropoiesis in response to low blood oxygen (hypoxia).
