Characterization of hcMSCs isolated from human BM. (A) Fibroblast-like shapes of hcMSCs on plastic culture dishes and crystal violet staining for clear visualization of hcMSCs. (B) Expression of several stem cell markers by using flow cytometry. (C) The multilineage potential of hcMSCs, adipogenic, osteogenic, and chondrogenic differentiation, and molecular markers of gene expression during each differentiation by reverse-transcription PCR. Original magnification, 40× and 100×. Aggrecan, large aggregating proteoglycan; aP2, activating protein 2; Col, collagen α1 chain; GAPDH, glyceraldehyde-3-phosphate dehydrogenase; LPL, lipoprotein lipase; M, marker; OCN, osteocalcin; PPARγ2, peroxisome proliferator-activated receptor γ2.

Effects of hcMSCs in rats with mild and severe AP. (A) Histologic analysis of AP. (B) Decreased apoptotic cells by hcMSCs in mild and severe AP. (C) Pancreas/body-weight ratio and activities of amylase (U/L), lipase (U/L), and MPO (U/mL). Each value represents the mean ± standard deviation of 4 separate experiments. *P < .05 and **P < .01, compared with mild and severe AP groups. Con, control; Con + hcMSCs, hcMSC-alone infusion group; AP, mild and severe AP group; AP + hcMSCs, hcMSCs infusion in mild and severe AP groups. Original magnification, 200×.

Tracking of infused hcMSCs. (A) Pancreas sections of CM-DiI–labeled hcMSCs at 1 × 106, injected into rats with or without mild or severe AP. (B) Human genomic AluI PCR from pancreas tissues. Sample 1, Con; samples 2 and 3, Con + hcMSCs; samples 4 and 5, mild AP + hcMSCs; samples 6 and 7; severe AP + hcMSCs; sample 8, human DNA. (C) Distribution of hcMSCs in various tissues. Distribution was assessed from pancreas, lung, liver, spleen, and kidney sections after CM-DiI–labeled hcMSCs (1 × 106) injection in rats with or without mild or severe AP. The numbers of CM-DiI–labeled hcMSCs represents the mean ± standard deviation of at least 10 fields. Con + hcMSCs, hcMSC-alone infusion group; mild and severe AP + hcMSCs, hcMSCs infusion in mild and severe AP group. Original magnification, 200×.

S, Sprague–Dawley rats; W, Wistar; A, B; PBMC donors; M, hcMSCs; L, lymphocytes. (B) Lymph node cells from rats were stimulated with indicated stimuli and Foxp3+ and (C) Annexin V expression were measured in CD4+ T cells. (D) Inhibition of T-cell infiltration and (E) expression of Foxp3+ by hcMSCs in pancreas tissues. Data represent the mean ± standard deviation for at least 5 fields. *P < .05 and **P < .01, compared with mild and severe AP. Con, control; Con + hcMSCs, hcMSC-alone infusion group; AP, mild and severe AP; AP + hcMSCs, hcMSC infusion in mild and severe AP. Original magnification, 200×.
