The validity of the methylene blue colorimetric microassay for determining the response of monolayers of human ovarian tumour cell lines to different growth factors was investigated. Linearity of the relationship between cell density and optical density was confirmed for each cell line (r=0.989-0.999,p<0.001), and when initial cell density was optimised to give exponential growth over the assay period, differences in response to medium supplements were obvious. The response of target cells to growth factors, obtained using the methylene blue assay, were compared with, and found to parallel, previously documented responses obtained non-colorimetrically. Thus Mink lung epithelial cells (MLEC) were inhibited by TGβ (Holleyet al., 1983), EGF had an inhibitory effect on A431 cells (Gill & Lazar, 1981; Barnes, 1982), and the mesothelial cell line showed a proliferative response to EGF and hydrocortisone (Connell and Rheinwald, 1983).The methylene blue colorimetric microssay was found to be a simple, reliable, sensitive method with low variability, for determining the response of cultured cells to growth factors.
