Synthesis of sulfated glycosaminoglycans by the three cell types of the rabbit cornea in culture. | Rabbit corneal cells were cultivated for 21 days and then exposed to Na235SO4, a precursor of sulfated glycosaminoglycans (GAG). All 3 cell types of the cornea, the fibroblasts, the epithelial as well as the endothelial cells, synthesize GAG. The fractionation-patterns of the epithelial and endotherlial GAG are almost ... | 129,334 | [

A multifactorial system controlling myeloid cell differentiation and division. | It has been demonstrated that mature granulocytes contain two stimulatory and three inhibitory factors of cell proliferation. Consequently, beyond the negative feedback inhibitor (chalone), myeloid cells are controlled presumably by other negative (inhibitory) and positive (stimulatory) mechanisms, in addition. | 131,223 | [
