Proliferation of mesenchymal stem cells from control (MSC-CTRL) and sarcoma (MSC-SAR) patients during in vitro expansion. Cumulative population doubling (CPD) from MSC-CTRL (n = 6) and MSC-SAR (n = 6) during seven passages. Results are expressed as best-fit linear regression lines (solid lines) with 95% < confidence intervals (dashed lines).
