IP injected MSC localized to the omentum and recruit immune cells. a Ex vivo fluorescent images of the omenta excised from GFP-MSC-injected BALB/c mice. To help in visualization of the GFP signal in the transparent omentum, reversed logarithmic grayscale was applied to the images. Black areas correspond to the GFP-positive signal. Omenta were isolated from MSC- or HBSS-injected animals, weighed, digested and analyzed by flow cytometry. b Scatter plots represent weights of individual omenta. c Total cells after digestion and d total macrophages at 3 days after injections. Error bars are ± SEM. *P < 0.05, **P < 0.01, ***P < 0.001 compared to HBSS. GFP green fluorescent protein, HBSS Hank’s Balanced Salt Solution, MSC mesenchymal stem cells
