FIG 12.

Time course of changes in cytokine expression and intramuscular myeloid cell populations after acute muscle injury, compared with those after experimental infection with a sublethal inoculum of C. perfringens. (A) Expected cytokine expression and changes of myeloid cell populations after acute muscle injury. (Adapted from reference 27 with permission of the publisher.) (B) Cytokine expression and changes of myeloid cell populations after intramuscular infection with a sublethal inoculum of C. perfringens. Asterisks indicate critical points for muscle regeneration that were affected in this model.
