Mean cytokine levels (pg/ml) in supernatants of in vitro stimulated splenocytes of implanted (BOV, CYP) and control groups (SHAM) determined using an enzyme-linked immunosorbent assay (ELISA) 7 days (green bars) and 14 days (yellow bars) after surgery. Cultures of mouse splenocytes were incubated in supplemented RPMI 1640 medium alone (C, negative control), with pokeweed mitogen (PWM, positive control), with bovine and carp gel (gBOV or gCYP), and bovine and carp implant (iBOV or iCYP). After a 72-hour incubation, the cultures were centrifuged and cytokine expression was measured in supernatants. All differences are not significant.
