Figure 2: Mesenchymal stem cell (MSC) viability (Y-axis) after freezing with 10% DMSO and at different time points (X-axis) immediately after thawing (A). The influence of different anaesthetics on MSC viability was tested at different hours (h) (X-axis) after mixing the MSCs with the following substances: Mepivacaine (Mep) with (+) or without (-) Adrenaline (Adr) and Procaine (B). The control represents MSCs in 1 ml of DMEM diluted with 2 ml of PBS 1x.
