Frozen sections were prepared at 21 days after transplantation of ADSCs labeled with DiI dye. (a) Magnified microphotographs of sagittal sections of hematoxylin and eosin-stained specimens collected from the ADSC group 21 days after surgery. (b) Grayscale values of frozen sections of each tissue (40× magnification); these values were similar to those for the frozen section in (c). Scale bar, 1 mm. (c) Frozen section with DiI labeling (40× magnification. Scale bar, 1 mm). (d) High-magnification image (500×) of the boxed region in (c). Scale bar, 100 μm. HS = healthy skin; GT = granulation tissue; B = cranial bone.
