Developmental change in the glycosaminoglycan composition of the chick embryo brain.
GAGs content was examined in chick embryo brain starting from the 9th day of incubation to the 4th post-hatching day. Chondroitin 6-sulfate, hyaluronate and heparan sulfate were recovered at any developmental stage examined. C6-S was the main GAG (except on the 15th day), while HS was the least represented. The highest differences in the relative amounts of GAGs are observed on the 9th day. C6-S shows high developmental relative changes, while HA and HS exhibit a similar pattern.
