In vivo fluorescent imaging of GFP-MSC in the peritoneal cavity. a Depiction of GFP-MSC distribution in the peritoneal cavity of BALB/c mice 24 h after IP administration. Yellow dashed lines outline GFP-positive areas (bright white) corresponding to the omentum, aggregates and portions of mesentery. b Representative images of the peritoneum of BALB/c mice injected IP with GFP-MSC and followed by in vivo fluorescent imaging. Bright white areas correspond to the areas of GFP-positive cells. Logarithmic grayscale was applied to panels (a) and (b) to help in visualization of the GFP signal
