Viability of UCS cells was determined using the tetrazolium compound based CellTiter 96® AQueous One Solution Cell Proliferation (MTS) assay (Promega). Cells were plated in 96 well plate at density of 2.5x 103 cells per well. 4h post serum starvation cells were subjected to TGFβ-I (R&D Biosystems) treatment alone or in presence of LY2157299 [40 (link)] (TGFβR-I inhibitor, Selleck Chem), LY2109761 [41 (link)] (TGFβR-I/II inhibitor, Selleck Chem), 10058-F4 (c-Myc Inhibitor, Sigma Aldrich), NFAT inhibitor (Cay-man Chemicals). After 24h treatment MTS assay was done and viability was calculated using vehicle as 100%. [42 (link)].
