Immunohistochemical methods were employed to examine alterations in the cartilage extracellular matrix constituents associated with endochondral ossification in humans. The distributions of chondroitin 4- and 6-sulfate and keratan sulfate proteoglycan (PG) determinants, cartilage PG link protein, collagen types I and II, and fibronectin were determined in(More)
The importance of glutamine for the synthesis of proteins of the extracellular matrix was investigated in cultured mesangial cells. Glutamine at 2 mM elicited an increase in smooth muscle cell alpha-actin, alpha(1)-type IV collagen and fibronectin transcripts (19.0-, 16.7-, and 4.3-fold, respectively) accompanied by an increase in alpha-actin stress fibres(More)
