Bone marrow comprises approximately 5% of total body mass in healthy adult humans, such that a person weighing 73 kg (161 lbs) will have around 3.7 kg (8 lbs) of bone marrow. [ 5 ] Human marrow produces approximately 500 billion blood cells per day, which join the systemic circulation via permeable vasculature sinusoids within the medullary ...
It is well known that stromal cells arise and are stored in the bone marrow until maturation and differentiation. They are located in the stroma and aid hematopoietic cells in forming the elements of the blood. [8] While a majority is found in the bone marrow scientists now know that stromal cells can be found in a variety of different tissues ...
Stromal tissue falls into the "functional" class that contributes to the body's support and movement. The cells which make up stroma tissues serve as a matrix in which the other cells are embedded. [2] Stroma is made of various types of stromal cells. Examples of stroma include: stroma of iris; stroma of cornea; stroma of ovary; stroma of ...
Stroma (tissue), the connective, functionally supportive framework of a biological cell, tissue, or organ (in contrast, the parenchyma is the functional aspect of a tissue) Stroma of ovary, a soft tissue, well supplied with blood, consisting of spindle-shaped cells with a small amount of connective tissue; Stroma of iris, fibres and cells in ...
Myeloma bone disease is due to the overexpression of receptor activator for nuclear factor κ B ligand by bone marrow stroma. RANKL activates osteoclasts , which resorb bone. The resultant bone lesions are lytic (cause breakdown) in nature, and are best seen in plain radiographs, which may show "punched-out" resorptive lesions (including the ...
Although reticular fibers are widely distributed in the body, reticular tissue is limited to certain sites. It forms a labyrinth-like stroma (literally, "bed or "mattress"), or internal framework, that can support many free blood cells (largely lymphocytes) in lymph nodes, the spleen, and red bone marrow.

The first published English grammar was a Pamphlet for Grammar of 1586, written by William Bullokar with the stated goal of demonstrating that English was just as rule-based as Latin. Bullokar's grammar was faithfully modeled on William Lily's Latin grammar, Rudimenta Grammatices (1534), used in English schools at that time, having been ...
