Bone Marrow Histology
Make it clearer
Bone marrow histology looks like a busy landscape. Picture islands of developing blood cells surrounded by sinusoids, which are vascular channels, with bony trabeculae running between them.
The marrow also contains adipocytes, the cells that store fat, and cells that make up blood vessels. As blood cells mature, they reach the venous sinusoids and enter the circulation from there.
In brief
In bone marrow histology, hematopoiesis takes place in islands of blood-forming tissue surrounded by vascular sinusoids and interspersed with bony trabeculae.
Picture islands of developing cells arranged around vascular channels.
Hematopoietic tissue contains blood cells at different stages of development; adipocytes, or fat cells; and vascular cells. As blood cells mature, they enter the circulation from the marrow through venous sinusoids.
