- Hematopoiesis
It is comprised of hematopoietic cells in various stages of development, supportive reticular connective tissue, and sinusoidal capillaries. Hematopoietic stem cells give rise to red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
Summary of the morphologically recognizable hematopoietic cells and mature cells found in bone marrow. Red Blood Cells (erythrocytes) Large, round nuclei condensing extruded
Bone Marrow Structure and Function. The bone marrow is found within the central cavities of axial and long bones (Figure 1). It consists of hematopoietic tissue islands and adipose cells surrounded by vascular sinuses interspersed within a meshwork of trabecular bone.
9 Νοε 2023 · The bone marrow is colonized by haematopoietic stem cells in the 11th week of gestation; long after blood cells production has ceased in the yolk sac, and is well underway in the thymus and liver. Red bone marrow (histological slide)
1 Μαΐ 2023 · The specific cells which are predominant in each microscopic area of the bone marrow are largely dependent on the niche of signaling cells at that site, which can include mature HSC, osteoblasts, macrophages, stromal cells, endothelial cells, and adipocytes among others.
Virtual microscope slides of bone marrow - development of red blood cells, platelets, neutrophils, eosinophils, basophils, lymphocytes, and monocytes.
