BMSC-Derived Exosomes Ameliorate LPS-Induced Acute Lung Injury by miR-384-5p-Controlled Alveolar Macrophage Autophagy

Figure 1

Characterization and differentiation of BMSCs. Fluorescence-activated cell sorting (FACS) analysis demonstrated that BMSCs expressed high levels of CD29 (a), CD44 (b), CD90 (c), and CD105 (d) but were negative for CD11b/c (e), CD34 (f), and CD45 (g). After osteogenic, chondrogenetic, and adipogenic medium induction, the BMSCs showed alizarin red-positive calcium nodule (h), numerous acid mucopolysaccharide (i), or oil-red-O-positive lipid droplets (j), respectively (×200 magnification).
