In the original publication [1], there was a mistake in Figure 7 as published. In Figure 7A, due to an inadvertent error, the same mouse image was used twice. The corrected Figure 7 appear below. The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.

Influence of cryopreservation on in vivo distribution of GFP-Fluc-UCMSCs. (A) Bioluminescence images to monitor the in vivo distribution of GFP-Fluc-UCMSCs in mouse model. (B) Quantification of total photon flux from GFP-Fluc-UCMSCs in mouse model. (C) Bioluminescence images to monitor the distribution of GFP-Fluc-UCMSCs in mouse organs. The organs were arranged as heart, liver, spleen, lung, kidney, and intestines. (D) Quantification of total photon flux from GFP-Fluc-UCMSCs in mouse organs. Control group refers to UCMSCs without cryopreservation and transgene treatment. Fresh cell refers to GFP-Fluc-UCMSCs without cryopreservation process. DMSO refers to GFP-Fluc-UCMSCs cryopreserved by traditional protocol based on DMSO. B–E refers to GFP-Fluc-UCMSCs cryopreservation using betaine combined with electroporation at optimum condition. Value = mean ± standard deviation, n = 4.
