Abstract

A microculture technique for the evaluation of the metabolic activity of corneal cells is described and analyzed. The extent of DNA synthesis in microcultures with 10(3) to 2.5 X 10(3) cells per well was initially low during day 1, increasing steadily thereafter. Higher initial concentration of 10(4) to 2 X 10(4) cells per microculture demonstrated a high metabolic activity during days 1 and 2 in culture, followed by a rapid and marked decrease on days 3 and 4. The origin and concentration of serum in the system have been found to be crucial. Xenogeneic serum (fetal calf serum--FCS) had the most potent stimulatory effect on DNA and protein synthesis. Syngeneic serum (guinea pig serum, strain 13--SGpS) or allogeneic serum (guinea pig serum strain 2--AGpS) had a generally less stimulatory effect on the metabolic activity. However, both sera had a relatively much stronger effect on the protein synthesis.
