The authors regret to state that an error was made in Fig. 5J. Mainly, the GelMA-treated group was mislabelled as the control group in the liver columns. The mean values for the control and the GelMA treated-groups are 0.874 and 0.872, respectively. Below please find the corrected Fig. 5. The authors apologise for any inconvenience caused.

Fig. 5. In vivo safety study of UCNPs. The H&E staining of heart (A), lung (C), liver (E) and kidney (G) tissues from rats implanted with UNCP-labeled GelMA hydrogel implantation for 7 days, and heart (B), lung, (D) liver (F) and kidney (H) tissues obtained from rats without hydrogel implantation, respectively. (I) Western blot analysis of active cleaved caspase 12 in lung, liver, spleen, kidney and heart tissues obtained from rats with UNCP-labeled GelMA hydrogel implantation as compared to the control group without implantation. (J) WB bands were normalized to b-actin.
