Kinetics of the cytokine effects on HUVEC (▪) and MIEC (▒) expressed as percentage increase over untreated controls. Six‐thousand cells/well were incubated for 24 h (a) and 48 h (b) in serum‐free basal medium in the presence or absence (control) of 100 ng/ml of the respective growth factor. In general, the response of MIEC increases, whereas that of HUVEC decreases from 24 to 48 h. *P < 0.05, #P < 0.01, §P < 0.001 vs. untreated control.
