| progenitor cell | <cell biology> In development a parent cell that gives rise to a distinct cell lineage by a series of cell divisions. (18 Nov 1997) |
|---|---|
| progenitor cell transplant | (stem cell transplant, blood cell transplant): The transplantion of parent cells which may give rise to progeny (daughter cells) which erve more specialised functions. Transplants may be from the peripheral blood or bone marrow. The patient himself/herself may be the donor (autologous transplant), a (genetically) compatible relative or individual (allogeneic transplant). (16 Dec 1997) |
| platelet endothelial cell activated protease | <enzyme> Degrades casein and fibrinogen; secreted by endothelial cells and activated in the extracellular medium by platelets; not inhibited by serine protease inhibitors, metalloproteinase inhibitors, or cystein protease inhibitors; pH optimum 7.5 Registry number: EC 3.4.99.- Synonym: pecap (26 Jun 1999) |
| endothelial cell | A thin, flattened cell, a layer of them lines the inside surfaces of body cavities, blood vessels, and lymph vessels, making up the endothelium. (09 Oct 1997) |
| progenitor | A precursor, ancestor; one who begets. Origin: L. (05 Mar 2000) |
| O 2A progenitor | Bipotential progenitor cells in rat optic nerve that give rise initially to oligodendrocytes and then to type 2 astrocytes. Production of type 2 astrocytes from O 2A progenitor cells in vitro is triggered by ciliary neurotrophic factor (CNTF). (18 Nov 1997) |
| erythroid progenitor cells | Committed, erythroid stem cells derived from myeloid stem cells. The progenitor cells develop in two phases: erythroid burst-forming units (bfu-e) followed by erythroid colony-forming units (cfu-e). Bfu-e differentiate into cfu-e on stimulation by erythropoietin, and then further differentiate into erythroblasts when stimulated by other factors. (12 Dec 1998) |
| vascular endothelial growth factor | A growth factor that is responsible for the growth of blood vessels. (12 Dec 1998) |
| corneal endothelial polymorphism | A greater than normal variation in the shape of the cells. (05 Mar 2000) |
| high endothelial postcapillary venules | Venule's in the lymph nodes, tonsils, and Peyer's patches that have a high-walled endothelium through which blood lymphocytes migrate into the lymphatic parenchyma. (05 Mar 2000) |
| intravascular papillary endothelial hyperplasia | A benign florid papillary endothelial proliferation within the veins of the skin or subcutis, less often in visceral blood vessels. Synonym: Masson's pseudoangiosarcoma. (05 Mar 2000) |
| iridocorneal endothelial syndrome | <syndrome> Syndrome of glaucoma, iris atrophy, decreased corneal endothelium, anterior peripheral synechia, and multiple iris nodules. Synonym: Cogan-Reese syndrome, iris-nevus syndrome. (05 Mar 2000) |
| endothelial | Pertaining to or made up of endothelium. (16 Dec 1997) |
| endothelial cyst | A serous cyst whose sac is lined with endothelium. (05 Mar 2000) |
| endothelial dystrophy of cornea | Spontaneous loss of corneal endothelium leading to oedema of the corneal stroma and epithelium. (05 Mar 2000) |
