Endosteum
Definition:
(n.) The layer of vascular connective tissue lining the medullary cavities of bone.
Example Sentences:
(1) It is concluded that the tissue in diffusion chambers, formed by a small number of early precursor cells present in the soft tissues of the endosteum and marrow of young rabbits, contains extracellular matrix macromolecules similar to those found in bone and cartilage.
(2) With bead types II and III, bead-associated new bone was seen at 3 days and 4 days only when beads lodged near the endosteum or in the metaphysis.
(3) However, the increase in rate of influx when the cellular layers are removed indicates that the periosteum and endosteum constitute an important structural conponent in the maintenance of bone mineral and its equilibration with the circulation.
(4) Immunohistochemistry of normal and neoplastic tissues demonstrated that RCB1 bound the connective tissues surrounding the cancer nests and various normal tissues including interstitium of renal distal tubule, periosteum, endosteum, smooth muscles of digestive tract and media of arteries and arterioles.
(5) Our studies of 2 microns sectioned undecalcified plastic-embedded bone marrow (BM) from healthy human fetuses; normal adults; patients with acute myeloblastic leukemia (AML), acute lymphoblastic leukemia (ALL), and chronic granulocytic leukemia (CGL) in various stages (chronic, accelerated, acute blastic phase, and after autografting); and patients recovering from therapy-induced marrow hypoplasia suggest that proliferative hematopoietic zones exist near the endosteum (endosteal marrow) and the vascular endothelium (capillary and sinus-lining endothelium) and a maturational zone distal to these regions.
(6) Surgical interference within the blood supply to the inner ear was responsible for metaplastic bone, and damage to the endosteum by surgery or disease caused osteoplastic bone.
(7) Endosteum is the main source of the regeneration of the stromal elements.
(8) General and some special histologic methods have been used to study the structure of periosteum and endosteum, as well as the morphological peculiarities of their cells in rodents and hares in the early and late postnatal ontogenesis.
(9) The findings show the existence of antibodies directed against the cell nuclei, or against the endothelium of the cochlear vessels, or against the endosteum of the inner ear.
