Fig. 4From: Automated image analysis detects aging in clinical-grade mesenchymal stromal cell culturesMean cell area increases with extended in vitro cell culture. Mean cell area is presented in function of a population doubling (PD) numbers and b passages after outlier filtering (n = 6). Each point in the graph presents imaged passages 1, 3, 5 or p6–9 (pSEN). Standard deviations are omitted from the graph for clarityBack to article page
