Table 2 Human experimental groups

From: Immunogenicity of unprocessed and photooxidized bovine and human osteochondral grafts in collagen-sensitive mice

HColl/CFA (n = 8 for comparison to 4-week groups) (n = 4 for comparison to 12-week groups) Positive control; human collagen with complete Freund's adjuvant, euthanized 3 weeks after injection
HColl/IFA (n = 8 for comparison to 4-week groups) (n = 4 for comparison to 12-week groups) Positive control; human collagen with incomplete Freund's adjuvant, euthanized 3 weeks after injection
Hu-UP-4 (n = 8) Unprocessed human graft, 4 weeks implantation
Hu-P-4 (n = 8) Photooxidized human graft, 4 weeks implantation
Hu-S-4 (n = 4) Negative control; sham operation, euthanized 4 weeks post-op
Hu-UP-12 (n = 8) Unprocessed human graft, 12 weeks implantation
Hu-P-12 (n = 7) Photooxidized human graft, 12 weeks implantation
Hu-S-12 (n = 8) Negative control; sham operation, euthanized 12 weeks post-op
  1. H or Hu = human; UP = unprocessed; P = photooxidized; S = sham
