Chemotactic feature of hAd-MSCs. (A) Histological analysis by frozen section: (a) white light imaging, (b) fluorescent imaging and (c) merge; magnification ( × 100). Scale bar, 200 μm. (B) mRNA expression of SDF-1 in intestine on the 10th day after abdominal irradiation. The left image represents electrophresis in 1.5% agarose gel. Lane 1: normal+PBS, lane 2: normal+MSC and lane 3: WAI+PBS, lane 4: WAI+MSC. The right one represents quantitative analysis of SDF-1 expression. Fold expression values were normalised to normal Sprague–Dawley rat. Data represent mean±S.D. of three independent measurements (n=3). *P≤0.05, **P≤0.001
