Question

Quizplus · Accepted Answer

Hematopoiesis in the bone marrow is chiefly controlled by stromal components, which include cells like fibroblasts, adipocytes, and endothelial cells. These cells release hormones and growth factors that regulate the proliferation and differentiation of hematopoietic stem cells. The amount of fat present in the bone marrow can affect hematopoiesis, but it is not the main controller. The vasculature is important for delivering nutrients and oxygen to the bone marrow, but it is not chiefly responsible for controlling hematopoiesis. The number of osteoblasts present is important for maintaining bone tissue, but it is not involved in regulating hematopoiesis.
