Fig. 7: Antibody formation persisted in PEG-sensitized mice and was detected in naive mice after PEG hydrogel implantation.
From: Impact of PEG sensitization on the efficacy of PEG hydrogel-mediated tissue engineering

A PEG sensitization contributed to IgM and IgG antibody formation post-implantation of treatment groups in sensitized mice. B Naive mice also formed IgM antibodies post-implantation of PEG treatment groups. Dots represent individual specimens, and the black bars are the median of the sample group (n = 4 mice per sensitized treatment group; n = 3 mice per naïve treatment group).
