Sur les relations entre la production d'hexosamines et d'hydroxyproline de la part de fibroblastes cultivés in vitro dans différentes concentrations d'O2

Summary Studies and comparison of the hexosamine and hydroxyprolin production by fibroblasts cultivated in vitro at different oxygen concentrations. The results show that the highest hexosamine production occurs at a low oxygen concentration (5%). The highest hydroxyprolin production occurs at 20% O₂; this oxygen concentration is considered as an hyperoxic one for fibroblasts cultivated in vitro. Besides it has been ascertained that the highest sulphated MPS production occurs between 5 and 20% oxygen without any significant variation.
