Question

Which of the following statements about colony-stimulating factors (CSFs)is False?
A) CSFs are required to induce both cell division and cell maturation.
B) CSFs regulate leukopoiesis.
C) CSFs are made by epithelial cells.
D) CSFs regulate leukopoiesis and CSFs are made by epithelial cells.

CSFs are typically made by immune cells or stromal cells, not epithelial cells. The other statements are true: CSFs regulate leukopoiesis (the production of white blood cells) and are required for both cell division and maturation.
