Fig. 1From: Eicosapentaenoic acid potentiates the therapeutic effects of adipose tissue-derived mesenchymal stromal cells on lung and distal organ injury in experimental sepsisCharacterization of adipose tissue (AD)-derived MSCs by flow cytometry. Nonpreconditioned (a) and EPA-preconditioned (b) AD-MSCs similarly demonstrated lack of expression of CD45, CD31, and MHCII, but expressed CD29, CD49e, and CD44, as determined by flow cytometry. Isotype controls were used as negative control (light gray histograms). Y-axis: cell count; X-axis: fluorescence intensity. c Note the homogeneous fibroblastoid morphology of adherent AD-MSCs, which is similar in nonpreconditioned (AD-MSC) and EPA-preconditioned AD-MSCsBack to article page
