Density of intact parasites (mean ± SEM) in the skin lesion of BALB/c mice infected with Leishmania (V.) panamensis promastigotes with and without preincubation with IGF-I. Leishmania (V.) panamensis promastigotes preincubated with 50 ng/ml of IGF-I (open column) or without IGF-I (solid column) were injected in the hind footpad, and the skin samples taken from five animals from each group at different time points were submitted to morphometric analysis as stated in Materials and Methods.
