ATP-induced increase in cytosolic Ca2+ is mediated by P2 receptor activation in precursors from the hOE. Clonal cells were cultured for 3 days to study the change in cytosolic Ca2+ by microfluorometry using the fluorescent indicator Fura-2 AM. Two pulses of ATP were applied with an interstimulus interval of 15 min to determine the response reproducibility (a) (). (b) shows that the Ca2+ increase induced by ATP was blocked by suramin (). Data represent the and were compared by a Student test. .
