Simultaneous localization of type II collagen and core protein of chondroitin sulfate proteoglycan in individual chondrocytes. 1979

B M Vertel, and A Dorfman

In order to investigate the coordinated synthesis of matrix components by individual chondrocytes, specific antibodies to type I collagen, type II collagen, and chondroitin sulfate proteoglycan core protein were used in simultaneous double immunofluorescence reactions. Extensive accumulation of core protein surrounding chondrocytes and the intracellular accumulation of type II collagen were observed. Extracellular core protein immunofluorescence obscured the intracellular reaction product, but the extracellular immunoreactive material could be removed by digestion with purified testicular hyaluronidase prior to fixation. Subsequent to digestion, core protein and type II collagen were observed in the same chondrocytes within discrete, sometimes identical, cytoplasmic regions, thus demonstrating the simultaneous localization of these two products characteristic of differentiating cartilage.

D002478	Cells, Cultured	Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others.	Cultured Cells,Cell, Cultured,Cultured Cell
D002642	Chick Embryo	The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching.	Embryo, Chick,Chick Embryos,Embryos, Chick
D002807	Chondroitin	A mucopolysaccharide constituent of chondrin. (Grant & Hackh's Chemical Dictionary, 5th ed)
D002809	Chondroitin Sulfates	Derivatives of chondroitin which have a sulfate moiety esterified to the galactosamine moiety of chondroitin. Chondroitin sulfate A, or chondroitin 4-sulfate, and chondroitin sulfate C, or chondroitin 6-sulfate, have the sulfate esterified in the 4- and 6-positions, respectively. Chondroitin sulfate B (beta heparin; DERMATAN SULFATE) is a misnomer and this compound is not a true chondroitin sulfate.
