New research, published in the scientific journal *International Journal of Molecular Sciences*, explores how enriching platelet-rich plasma (PRP) with extraplatelet bioactive molecules can enhance its anti-inflammatory and antioxidant activity.

The study compares conventional PRP with a formulation enriched with bioactive molecules, called Balanced Protein-Concentrate Plasma (BPCP), in an in vitro experimental model that replicates inflammatory conditions associated with osteoarthritis by co-culturing human chondrocytes and synoviocytes.

The results show that both formulations reduce various inflammatory mediators and levels of oxidative stress. Furthermore, the BPCP formulation exhibits more pronounced effects on some of the analyzed parameters, suggesting the value of further investigating the role of extraplatelet molecules in optimizing biological therapies.

This study represents a new step forward in researching the mechanisms of action of PRP and in the search for increasingly optimized biological formulations.
