The greater omentum prolonged the survival of MSCs for at least 5 days in vivo. a Representative images of mice obtained using in vivo fluorescence imaging on days 1, 3, 5, and 7. The fate of RFP-MSCs after transplantation was tracked using in vivo fluorescence imaging. b Fluorescence intensity of RFP-MSCs after the transplantation at three different cell densities (2 × 10⁶, 2 × 10⁷, and 1 × 10⁸ cells per mice) in the AAN mouse model. c SNR of RFP-MSCs after the transplantation of different cell densities in the AAN mouse model. The red dashed circles represent the range of measurement allowed
