Fig. 1From: Alterations of mesenchymal stromal cells in cerebrospinal fluid: insights from transcriptomics and an ALS clinical trialMorphology and viability of MSCs cultured in CM, PLF media, and human or artificial CSF. a Morphology of MSCs imaged after 24 h in CM, PLF media, or hCSF. Cells were stained with phalloidin AF488 (green), DAPI (blue), and MitoTracker CMX-Ros (red). Images were taken at 40x magnification. b Metabolic activity of MSCs via MTS assay after 24–96 h in CM. c Metabolic activity of MSCs via MTS assay after 24–96 h in PLF media. d Metabolic activity of MSCs via MTS assay after 24–96 h in aCSF (n = 3, mean ± standard deviation)Back to article page
