Cytokine Production by Wound Macrophages^a

	TNF-α (pg)	IL-6 (pg)	TGF-β (pg)
Day 1	47.6 ± 4.1b	7.9 ± 0.9b	17 ± 1b
Day 7	7.5 ± 9.4	ND	52 ± 2

^aMacrophages isolated from wounds were cultured in complete medium for 24 h or in serum-free medium for 72 h (for TGF-β determination only). Data are cytokine production/3 × 10⁵ macrophages, mean ± sd of quadruplicate wells, and are representative of two experiments. IL-10 and IL-12p70 were not detected in culture supernatants. 

^bP < 0.05 versus Day 7 macrophages, Student’s t-test. ND, Not detected.
