The change of the cellular ATP concentrations in MEFs upon exposure to a free ATP or b DPTE-tbFGF- and DPTE-GALA containing POPC liposomes with encapsulated ATP. In this case, MEFs were incubated for 6 h at 37 °C and the cellular ATP levels were measured after 12 h with Luciferin/Luciferase based assay (see main text for details)Back to article page
