Studies of the haemopoietic microenvironments. III. Glycosaminoglycan levels in relation to phenylhydrazine-induced erythropoiesis in the mouse liver. 1980

E M Noordegraaf, and R E Ploemacher

The possible relation between haemopoietic activity and glycosaminoglycan levels in the haemopoietic microenvironment was examined in ectopic erythropoiesis, induced by phenylhydrazine treatment, in the liver of adult mice. The hepatic glycosaminoglycan content in the liver was determined biochemically over a period of 9 d following induction of haemolytic anaemia. After induction sulphated glycosaminoglycan levels increased up to d 4, then decreased to subnormal levels on d 5 and returned to normal values on the following days. The pattern of changes in GAG content coincided with changes in the number of CFU-S and with the number of erythroblasts in the liver. This observation fits in with the hypothesis of McCuskey et al (1972) stating that high sulphated glycosaminoglycan levels are favourable for stem cell proliferation, whereas low sulphated glycosaminoglycan levels favour erythropoiesis.

D008810	Mice, Inbred C57BL	One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D010659	Phenylhydrazines	Diazo derivatives of aniline, used as a reagent for sugars, ketones, and aldehydes. (Dorland, 28th ed)
D004920	Erythropoiesis	The production of red blood cells (ERYTHROCYTES). In humans, erythrocytes are produced by the YOLK SAC in the first trimester; by the liver in the second trimester; by the BONE MARROW in the third trimester and after birth. In normal individuals, the erythrocyte count in the peripheral blood remains relatively constant implying a balance between the rate of erythrocyte production and rate of destruction.	Erythropoieses
D006025	Glycosaminoglycans	Heteropolysaccharides which contain an N-acetylated hexosamine in a characteristic repeating disaccharide unit. The repeating structure of each disaccharide involves alternate 1,4- and 1,3-linkages consisting of either N-acetylglucosamine (see ACETYLGLUCOSAMINE) or N-acetylgalactosamine (see ACETYLGALACTOSAMINE).	Glycosaminoglycan,Mucopolysaccharides
D000743	Anemia, Hemolytic	A condition of inadequate circulating red blood cells (ANEMIA) or insufficient HEMOGLOBIN due to premature destruction of red blood cells (ERYTHROCYTES).

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
