| stem cell | 1. Cell that gives rise to a lineage of cells. Particularly used to describe the most primitive cells in the bone marrow from which all the various types of blood cell are derived. 2. More commonly used of a cell that, upon division, produces dissimilar daughters, one replacing the original stem cell, the other differentiating further (e.g. Stem cells in basal layers of skin, in haematopoetic tissue and in meristems). (13 Nov 1997) |
| stem cell factor | <growth factor> Haemopoietic growth factor 18.6 kD from sequence, found as dimer (35 kD protein, 53 kD in its glycosylated form). Acronym: SCF (18 Nov 1997) |
| stem cell growth factors | <growth factor> Compounds, usually proteins, that make stem cells grow faster. (26 Mar 1998) |
| stem cell leukaemia | A form of leukaemia in which the abnormal cells are thought to be the precursors of lymphoblasts, myeloblasts, or monoblasts. Synonym: embryonal leukaemia. (05 Mar 2000) |
| stem-clasping | <botany> Embracing the stem with its base; amplexicaul; as a leaf or petiole. Source: Websters Dictionary (01 Mar 1998) |
| quiescent stem cell | A stem cell that is not at that time undergoing repeated cell cycles but that might be stimulated so to do later. For example: the satellite cells in the skeletal muscles of mammals that are quiescent myoblasts that will proliferate after wounding and give rise to more muscle cells by fusion. (18 Nov 1997) |
| infundibular stem | The neural component of the pituitary stalk that contains nerve tracts passing from the hypothalamus to the pars nervosa. Synonym: infundibular stalk. (05 Mar 2000) |
| tumour stem cell assay | <investigation> A cytologic technique for measuring the functional capacity of tumour stem cells by assaying their activity. It is used primarily for the in vitro testing of antineoplastic agent. (12 Dec 1998) |
| absorptive cells of intestine | Cell's on the surface of villi of the small intestine and the luminal surface of the large intestine that are characterised by having microvilli on their free surface. (05 Mar 2000) |
| air cells | Air-containing spaces in the skull. See: pulmonary alveolus. (05 Mar 2000) |
| air cells of auditory tube | Occasional small air cells in the inferior wall of the auditory tube, near the tympanic orifice, communicating with the tympanic cavity. Synonym: cellulae pneumaticae tubae auditivae, air cells of auditory tube. (05 Mar 2000) |
| Alpha cells | Alpha cell's of pancreas or of anterior lobe of hypophysis. (05 Mar 2000) |
| alpha cells of anterior lobe of hypophysis | Acidophil cell's that constitute about 35% of the cell's of the anterior lobe. There are two varieties: one that elaborates somatotropin, another that elaborates prolactin. (05 Mar 2000) |
| alpha cells of pancreas | Cell's of the islets of Langerhans that secrete glucagon. (05 Mar 2000) |
