Abstract

High recoveries of plaque-forming cells were obtained in a serum-free medium using 2-mercaptoethanol and SiO2. Under such conditions an increase in the number of plaque-forming cells occurred between the fourth and fifth day of incubation, as compared with cultures with foetal calf serum. The addition of glutathione to the medium had a stimulating effect, it was however not absolutely necessary for a positive response. The recovery of plaque-forming cells was strongly influenced by an interdependence of cell density and amount of SiO2 gel particles.

摘要

在使用2-巯基乙醇和二氧化硅的无血清培养基中可获得较高的蚀斑形成细胞回收率。在这种条件下,与含有胎牛血清的培养物相比,蚀斑形成细胞的数量在培养的第4天到第5天之间有所增加。向培养基中添加谷胱甘肽有刺激作用,但对于阳性反应来说并非绝对必要。蚀斑形成细胞的回收率受到细胞密度和二氧化硅凝胶颗粒量之间相互依存关系的强烈影响。
