✦ Synopsis


The effect of the concentration of Ca 2 + in the medium on the plating efficiency of human epidermal cells has been investigated. Primary cultures plated onto lethally irradiated mouse embryo fibroblasts showed not only increased colony formation at lowered (0.2 mM) Ca 2 + levels but also increased growth rate as indicated by greater colony size. On the other hand, secondary cultures showed little variation in plating efficiency and only small differences in colony size were apparent over the range 0.2-1.64 mM Ca 2+. Epidermal growth factor had no effect on the Ca 2 + dependence of primary or the Ca 2 + independence of secondary cultures.

The objective of this study was to determine if adenosine alters growth of mammary epithelium. Mouse mammary epithelial cells (NMuMG) were cultured in DMEM supplemented with 10% fetal calf serum. After serum starvation for 24 h, EGF (0-100 ng/ml) and/or adenosine (0-100 microM) was added. Adenosine
