C3H/He uninfected and T. cruzi infected mice untreated or treated with G-CSF for four weeks, beginning day 21 (acute) or 1 year (chronic) post-infection were subjected to cardiomyocyte measurements by histo-morphometry. Data are presented as mean ± S.D. from analysis of >100 cells at 400× (>10 microscopic fields/slide, 3–4 tissue-sections/mouse, n ≥ 6 mice per group
p < 0.05, vs. normal
p < 0.05 vs. infected/unaffected area). NI: uninfected control, NI + GCSF: uninfected-treated, I: infected, I + GCSF: infected-treated.
