ART PRP Plus by Celling Biosciences

The ART PRP PLUS system processes autologous whole blood at the point of care. The system recovers a high percentage of platelets and growth factors by allowing a selection of concentrate from a patented controlled collection system in the centrifuged stack. The integrated filter allows for the ultra-filtration of proteins from the platelet poor plasma.

The ART PRP™ Plus has all of the features of the ART PRP™ but includes an integrated filter system for the ultrafiltration of proteins from platelet poor plasma (PPP). By injecting the plasma from one syringe on Port “B “to another syringe on Port “C” the cells and proteins are forced through the hundreds of hollow, nanoporous fibers, and water and salt ions are pushed out while proteins and cells are further concentrated. The fluid may be concentrated by passing through the filter multiple times until the desired volume is obtained. This ultrafiltration enriches the concentration of most proteins like Alpha-2 Macroglobulin (A2M), Interleukin-1 receptor antagonist protein (IRAP), Vascular endothelial growth factor (VEGF), Platelet-derived growth factor (PDGF), Transforming growth factor beta (TGF – beta), Fibroblast growth factors (FGF), Fibronectin and Fibrinogen7,8 , 9. A2M is a powerful natural plasma protease inhibitor, cytokine carrier, and ligand for cell-signaling receptors, and is synthesized primarily in the liver but dispersed through the blood plasma in whole blood and in bone marrow9,10. A2M stops the progression of Osteoarthritis (OA) by preventing degenerative cartilage breakdown and assisting with cartilage repair 4,7,8.

It can also inhibit inflammatory cytokines, and it thus disrupts inflammatory cascades. In its plasma-soluble tetramer form, it encapsulates matrix metallo-proteinases (MMP’s) and other destructive enzymes common to arthritic tissue and slows or halts the breakdown of articular cartilage surfaces and other forms of the Extracellular Matrix (ECM)11. A2M also binds up pro-inflammatory molecules; TNF-a, TGF-b, and IL-1b7. While IRAP is present at much higher levels in bone marrow aspirate, the amount available in whole blood is still concentrated with the ART PRP Plus system9.


  • Nearly closed system offers multiple connection ports
  • Thumb-wheel allows precise recovery of the targeted cell layer
  • Large aperture collection window
  • Manual collection accommodates full spectrum of hematocrit
  • Adjustable Flow Valve diverts fluid without additional sterile breaks
  • Adjustable Flow Valve simplifies separation/combining of cells, growth factors and proteins
  • Thumb-wheel recovers high yields of platelets and growth factors
  • ART PRP™ Plus hyper-concentrates platelet poor plasma (PPP) using nanoporous fibers
  • ART PRP™ Plus reduces 60 ml whole blood to 25-30 ml of PPP and nano-filtration further concentrates to 3-5 ml concentrated PPP


  • Minimizes sterile breaks where contamination occurs
  • Easy separation of fluid fractions (e.g. PRP, PPP, fibrinogen, A2M, IRAP, etc.); Processes anywhere from 50 cc up to 60cc of whole blood
  • Eliminates turbulence reducing cell velocity that can lyse cells
  • Increases cell recovery rates; other fully automated designs compromise recovery rate (just like our previous ART 21 system)
  • Keeps Buffy Coat in the collection zone, yielding 3cc to 5cc on average of PRP (Buffy Coat) from a typical 60cc volume of whole blood
  • Manual manipulation is the critical feature that produces optimal recovery and a customized final product
  • Provides for the highest concentration so that more cells can be delivered in the smallest volume
  • Unmatched concentration of molecules (e.g. fibrinogen, alpha-2 macroglobulin, VEGF, IRAP & cytokines of similar molecular weights6)
  • User has option to process separate layers of the centrifuged stack without exposure to additional contaminants and the ability to deliver two separate therapies from one device

Importance of Clot Formation

  • Natural clot formation of cells, platelets, growth factors, and proteins has been shown to add considerably to long term cell viability in situ9,16,17. Additionally, clot formation prevents cell migration helping keep cells where the physician intends them to be.
