CenTrate BMA

Bone Marrow Aspirate Concentration Device


CenTrate is a proprietary bone marrow aspirate concentration device whose output produces a natural suspension of plasma proteins. 


Note: In addition to ACD-A, Heparin is also an appropriate anti-coagulant when processing the CenTrate device. See instructions for concentration guidelines.


Features of the CenTrate Device include:


  • Dual buoy design eliminates need to filter bone marrow prior to processing

  • 5-19x increase in MSCs compared to original bone marrow 

  • Natural fibrin matrix

  • 15-minute processing



Bone marrow is often aspirated to utilize the stem cells for tissue repair applications.

Bone marrow aspirate (BMA) is a rich source of MSCs and other osteoprogenitor cells in the body[1].


The Role of Bone Marrow: The role of bone marrow in the body is to create blood and the

vascular system. When bone marrow cells concentrate at an injury site they initiate new blood vessel formation to start the next phase of the healing process.


Bone Marrow Aspirate Concentrate
The CenTrate Bone Marrow Aspirate Concentration device efficiently concentrates cells and platelets in a natural suspension of plasma proteins in 15 minutes. The dual buoy design eliminates the need to filter bone marrow prior to processing. 

Contains Cells and Cytokines

  • Mesenchymal stem cells (MSCs)[2], endothelial progenitor cells (EPCs)[3], and hematopoietic stem cells (HSCs)[4].

  • High concentrations of interleukin-1 receptor antagonist (IL-1ra or IRAP)[5] and tissue healing growth factors[6]
