abstract：:Proteoglycan biosynthesis in developing chicken corneas was studied. Corneas free of scleral rims were prepared from 5- to 18-day-old chick embryos and labeled in vitro with [3H]glucosamine and [35S]sulfate. Then, the labeled medium and corneal proteoglycans were analyzed. Day 5 corneas synthesized mainly chondroitin ...
