| stem cells | Relatively undifferentiated cells of the same lineage (family type) that retain the ability to divide and cycle throughout postnatal life to provide cells that can become specialised and take the place of those that die or are lost. (12 Dec 1998) |

| 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) |
| tumour stem cells | <cell biology> Colony-forming cells which give rise to neoplasms. (12 Dec 1998) |
| abortion, multiple | Couples who have had 2 or more miscarriages (spontaneous abortions) have about a 5% chance that one member of the couple is carrying a chromsome translocation responsible for the miscarriages. (12 Dec 1998) |
| advanced multiple-beam equalization radiography | A variant of scanning equalization radiography using several X-ray beams. (05 Mar 2000) |
| amyloidosis of multiple myeloma | Foci of amyloidosis in mesenchymal tissues of some persons with multiple myeloma; no direct relation between amyloid and Bence Jones protein is conclusively known. (05 Mar 2000) |
| cancer, multiple myeloma | A bone marrow cancer involving a type of white blood cell called a plasma (or myeloma) cell. The tumour cells can form a single collection (a plasmacytoma) or many tumours (multiple myeloma). Plasma cells are part of the immune system and make antibodies. Because patients have an excess of identical plasma cells, they have too much of one type of antibody. As myeloma cells increase in number, they damage and weaken the bones, causing pain and often fractures. When bones are damaged, calcium is released into the blood leading to hypercalcaemia (excess calcium in the blood) and that causes loss of appetite, nausea, thirst, fatigue, muscle weakness, restlessness, and confusion. Myeloma cells prevent the bone marrow from forming normal plasma cells and other white blood cells important to the immune system so patients may not be able to fight infections. The cancer cells can also prevent the growth of new red blood cells, causing anaemia. Excess antibody proteins and calcium may prevent the kidneys from filtering and cleaning the blood properly Cancer, non-Hodgkin's lymphoma: A lymphoma is a cancer that develops in the lymphatic system. The most common symptom of non-Hodgkin's lymphomas is a painless swelling in the lymph nodes in the neck, underarm, or groin. Non-Hodgkin's lymphomas are diagnosed with a biopsy of an enlarged lymph node. Follow-up examinations are important after lymphoma treatment. Most relapses occur in the first 2 years after therapy.

| chromosomes in multiple miscarriages | Couples who have had more than one miscarriage (spontaneous abortion) have about a 5% chance that one member of the couple is carrying a chromsome translocation responsible for the miscarriages. (12 Dec 1998) |
| miscarriages, multiple, chromosomes in | Couples who have had more than one miscarriage have about a 5% chance that one member of the couple is carrying a chromsome translocation responsible for the miscarriages. (12 Dec 1998) |
