Immunocytochemistry of keratan sulfate proteoglycan and dermatan sulfate proteoglycan in porcine tooth-germ dentin.

Keratan sulfate proteoglycan and dermatan sulfate proteoglycan have been reported to inhibit collagen fibrillogenesis. We investigated their distribution in order to evaluate the role of proteoglycan in dentinogenesis. Specimens of porcine tooth-germ dentin and erupted teeth were the materials on which antibodies to keratin sulfate and dermatan sulfate proteoglycan were used. Predentin was foun...

Demonstration of a keratan sulfate-containing proteoglycan in atherosclerotic aorta.

Proteoglycans were isolated from either grossly normal or atherosclerotic pigeon aortas after extraction with 4 M guanidine hydrochloride and purification by ion-exchange and size-exclusion chromatography. The small-size proteoglycans (Kav 0.4, on Sepharose CL-4B) from both normal and atherosclerotic tissue contained primarily a dermatan sulfate proteoglycan with an intact molecular size of 220...

Purification of keratan sulfate proteoglycan from monkey cornea.

An explant culture of 15 cynomolgus monkey corneas was incubated with [35S]sulfate and [2-3H]mannose as labeling precursors. A 4 M guanidine HCl extract of the corneal stromas was prepared and combined with a 4 M guanidine HCl extract of stromas from 300 unlabeled corneas. The keratan sulfate proteoglycans in the combined extracts were purified by a combination of DEAE-cellulose chromatography,...

Keratan sulfate proteoglycan phosphacan regulates mossy fiber outgrowth and regeneration.

We have examined the role of chondroitin sulfate proteoglycans (CSPGs) and keratan sulfate proteoglycans (KSPGs) in directing mossy fiber (MF) outgrowth and regeneration in rat hippocampal slice cultures. MFs normally exhibit a very specific innervation pattern that is restricted to the stratum lucidum (SL). In addition, MFs in hippocampal slice cultures will regenerate this specific innervatio...

Distribution of proteoglycans antigenically related to corneal keratan sulfate proteoglycan.

Three antibodies reacting with corneal keratan sulfate proteoglycan were used to detect antigenically related molecules in 11 bovine and 13 embryonic chick tissues. Two monoclonal antibodies recognized sulfated epitopes on the keratan sulfate chain and a polyclonal antibody bound antigenic sites on the core protein of corneal keratan sulfate proteoglycan. Competitive immunoassay detected core p...
