What is the significance of endothelial cells in the regulation of hematopoiesis?

A They produce angiogenic factors that inhibit hematopoiesis
B They are not involved in the regulation of hematopoiesis
C They produce factors that support the homing of hematopoietic stem cells to the bone marrow
D They are involved in the degradation of hematopoietic growth factors
