Bromelain belongs to a group of protein-digesting enzymes obtained commercially from the fruit or stem of pineapple. Several studies demonstrated that bromelain exhibits various fibrinolytic, anti-edematous, antithrombotic, and anti-inflammatory activities supporting its application for many therapeutic benefits. The aim of this study was to analyze the effects of bromelain on the pro-wound healing activities and the regenerative properties of mesenchymal stem cells.
Mesenchymal stem cells were treated in vitro with bromelain alone or combined with dexamethasone sodium phosphate. Real-time polymerase chain reaction was performed to profile the expression of extracellular matrix components and remodeling enzymes, and cytokines.
The combination of bromelain and dexamethasone sodium phosphate induced a great activation of mesenchymal stem cells with an increase in hyaluronan and collagen production and anti-inflammatory cytokines release.
Based on the results of this in vitro study, the combined use of bromelain and dexamethasone sodium phosphate stimulated the pro-wound healing activities and the regenerative properties of mesenchymal stem cells better than bromelain and dexamethasone alone.
