LTX-315 treatment leads to extracellular release of DAMPs in vitro. Rat TMSCs were treated in vitro with 17 μM of LTX-315 (IC50) for selected time points (5, 10, 30 and 60 min), and analyzed for the release of ATP, Cytochrome c and HMGB1. (A) LTX-315-treated cells showed a rapid release of ATP into the supernatant with a peak around 10 min before a subsequent descent after 30 min. (B) Similarly, LTX-315-treated cells displayed an increase in cytochrome c release related to incubation time with a significant amount in the supernatant after 30 and 60 min. (C) Rat TMSCs treated with LTX-315 showed a translocation of the HMGB1 protein from the lysate (L) to the supernatant (S) using Western blot. Control cells showed no translocation after 60 min. All experiments were performed in triplicate, and quantitative data are presented as a mean ± SD.
