Title: Glutamine synthetase induction in chick embryo retina monolayers. Author: Dutt K, Reif-Lehrer L. Journal: Cell Biophys; 1981 Mar; 3(1):1-17. PubMed ID: 6167358. Abstract: Induction of glutamine synthetase (GS) by cortisol has been shown to occur in monolayer cultures of cells obtained by enzymatic dissociation of retinas from 8- and 12-day-old chick embryos with papain (0.1%) or trypsin (0.25%). Although essentially single cells when plated, monolayers obtained by enzymatic dissociation show significant aggregation by 4--6 h. Monolayers prepared by mechanical dispersion (cells forced through successively smaller gage needles) are minimally inducible, perhaps owing to poor viability in such cultures. Storage at 4 degrees C for 24 h prior to treatment with cortisol significantly elevated both basal GS activity and inducibility in whole (but not in monolayer) retina cultures.[Abstract] [Full Text] [Related] [New Search]
