    Only five minutes is needed to spin the sample in the Regen™ centrifuge and separate plasma and platelet sediment from the remaining cellular composition.

    By using the patient’s own blood to prepare the platelet concentrate, the RegenKit®  technology vastly reduces the risk of an adverse or allergic reaction.



Platelets are key factors in hard and soft tissue repair mechanisms. They provide the essential growth factors FGF, PDGF, TGF-ß, EGF, VEGF, IGF that are involved in stem cell migration, differentiation and proliferation. The stimulation of fibroblasts and endothelial cells induces new extracellular matrix deposition and neo-vascularization.

Plasma is essential for cell survival as it contains nutrients, vitamins, hormones, electrolytes and proteins. Proteins are key molecules for the coagulation process and the formation of the fibrin polymer that will serve as a scaffold for cell migration, differentiation and proliferation.


The Regen™ BCT (Blood Cell Therapy) tube prepares 5 to 6 ml of autologous platelet rich plasma with a platelet recovery greater than 80% and a concentration factor of 1.6-fold. Although the system is technically capable of producing significantly higher platelet concentrations, it is not what research shows to be beneficial for clinical use. More and more studies demonstrate that concentrations of platelets 1 to 3 times over the baseline show more robust healing rates than those with concentrations of 3 to 8 times the baseline1.

Some studies even showed that too high platelet concentrations may actually have negative effects. In a in vivo study2 it was shown that highly concentrated platelet preparations had an inhibitory influence on osteoblast activity, probably due to unwanted inhibitory and cytotoxic effects of growth factors at such high concentrations. Similarly, an in vitro study3 demonstrated that platelet concentration over 2.5-fold, resulted in a reduction in proliferation and a suboptimal effect on osteoblast function.


White blood cells are strongly reduced (> 85% depletion) with the Regen™ PRP® system.

The role of white blood cells (WBC) in healing is controversially discussed among physicians. To address this concern scientifically, WBC subsets, granulocytes and mononuclear cells, need to be looked at individually. Granulocytes, and more specifically neutrophils, are the front-line defenders against invading pathogens and are associated with the inflammatory response. They release a large variety of highly active antimicrobial substances and proteases. Uncontrolled release of these factors can cause severe damage to the tissue, delay healing rates and increase the risk of scarring4. Thanks for the Regen PRP® system, more than 96% of the granulocytes are removed from autologous platelet rich plasma. The few white blood cells still present in autologous platelet rich plasma are mostly mononuclear cells(lymphocytes and monocytes). These two cell types are also involved in thr immune response, but have also been shown to support the healing process5,6.
