The Marrow Cellution™ System maximizes stem and progenitor cell recovery and minimizes peripheral blood contamination.
Thus, it prevents the subsequent need for additional manipulation procedures such as centrifugation and/or chemical separation which usually require oversight by national regulatory authorities.
Bone Marrow Aspiration
The regenerative qualities of bone marrow have been used for decades and are considered the gold standard for stem cell harvesting. However, after the first 1-2 mL of bone marrow aspirate from a traditional needle, the number of total nucleated cells (TNC) in the aspirate drops dramatically due to the lower viscosity of blood and the design of the needle, which operates most optimally for small biopsy volume. After aspirating the first 1-2 mL of bone marrow, peripheral blood will preferentially fill the vacated space, limiting the additional harvest of key stem and progenitor cells.
The Marrow Cellution™ Bone Marrow Aspiration System overcomes this issue. It allows the user to aspirate in a measured and controlled manner over a large geography inside the marrow space, while restricting peripheral blood infiltration.
