Comparison of the inflammatory responses in autografts and allografts. (a) Immunostaining of cross-sections for macrophage markers at days 3, 14 and 28. (b) Immunostaining of cross-sections for T cell markers at days 3, 14 and 28. Lumen is marked with *. Scale bars: 50 μm. (c-h) Percentage of macrophages (c, d, e) and T lymphocytes (f, g, h) in the autografts and the allografts (* P < 0.05, ** P < 0.01). Data represent mean ± S.D. At least 15 fields of the same graft were pooled for cell counting. (n=5)
