30 Οκτ 2023 · This article will review the embryology of the bone marrow as well as its histology. Additionally, the constituent cell lineages and their function will be discussed, together with clinically relevant processes and pathologies.
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).
The development of blood cells (hematopoiesis) takes place in the bone marrow found within the marrow cavity of bones. In this course you will not be required to recognize the various stages of blood cell development in bone marrow slides. However, you should have some idea of the process.
Summary of the morphologically recognizable hematopoietic cells and mature cells found in bone marrow. Histology on the identification of hematopoietic cells in bone marrow.
19 Φεβ 2017 · The term ‘bone marrow’ (BM) refers to the tissue occupying the cavities under the cortex within the honeycomb of trabecular bone. Normal marrow is either red, consisting of the hematopoietic tissue, or yellow, composed mainly of fat cells (adipose tissue). In children most bones contain hematopoietic marrow, almost to the exclusion of fat cells.
The components involved in bone marrow histology are cortical and trabecular bone and stroma, vasculature, sinus wall layers, nerves, hematopoietic cells, and non-hematopoietic interstitial cells. Refer to Box 2, Box 3 for a checklist and list of histochemical stains used to assess bone marrow histologic specimens. Box 2.
