Thulium laser resection of the prostate (TmLRP), a major treatment for benign prostatic hyperplasia (BPH), has several postoperative complications that affect the patients' quality of life. The aim of this study was to investigate the effect of the M1 macrophage-secreted reactive oxygen species (ROS) on prostatic wound healing, and the role of MAPK signaling in this process. A co-culture model in vitro was established using macrophages and prostate epithelial or stromal cells. Cell proliferation, migration, apoptosis, MAPK pathway-related gene expression levels were evaluated by standard assays. In addition, an in vivo model of prostatectomy was established in beagles by subjecting them to TmLRP, and were either treated with N-acetyl-L-cysteine (NAC) and or placebo. Wound healing and re-epithelialization were analyzed histopathologically in both groups, in addition to macrophage polarization, oxidative stress levels and MAPK pathway-related proteins expressions. Intracellular ROS levels were significantly increased in the prostate epithelial and stromal cells following co-culture with M1-like macrophages and H2O2 exposure via MAPK activation, which affected their proliferation, migration and apoptosis, and delayed the wound healing process. The cellular functions and wound healing capacity of the prostate cells were restored by blocking or clearing the macrophage-secreted ROS. In the beagle model, increased ROS levels impaired cellular functions, and appropriate removing ROS accelerated the wound healing process. •ROS hindered the healing of prostatic wound caused by prostatectomy.•ROS impacted proliferation and migration of prostate epithelial and stromal cells.•ROS affected the prostatic wound healing via MAPKs signaling pathways.•ROS scavengers could decrease the ROS level and accelerate wound healing.
