Biocompatibility of ACPs in vivo. a Representative blood analysis data of rats after ACPs implant for 2 weeks. b-e Representative histological images of ACPs after they are planted in the dorsal subcutaneous space for 3 d (b), 1 week (c), and 2 weeks (d). e Representative histological images of the fibrin gels' position after they are planted in the dorsal subcutaneous space for 2 weeks (fibrin gels would fall off during the H&E staining process). For each image, similar results are obtained in 4 additional independent experiments. ACPs adhesive cryogel particles, GT granulation tissue (indicate the areas of inflammation), SM skeletal muscle
