Dental papilla implantation promoted the apoptosis of pro-inflammatory microglia apoptosis at the lesion site Quantification of cells positive for TUNEL and CD68 but negative for iNOS in the lesion and in each concentric circles around the lesion (A) and in the total surface analyzed (lesion + all concentric circles) (B) one week after implantation. Quantification of cells positive for TUNEL, and stained for CD68 and iNOS in concentric circles around the lesion (C) and in total surface analyzed (D). n = 3 Significant differences were analyzed using a mixed-effects model with geisser-Greenhouse correction. A Tukey test was used for simple effect within rows. Conditions not linked by the same letter are significantly different; *p < 0.05
