At first glance, that number looks underwhelming.
It's actually the whole point.
Mesenchymal stem cells are one of the rarest populations in bone marrow: between 0.001% and 0.1% of mononuclear cells. So recovering them at the very top of that range, from just 2 mL of aspirate and without a single spin in a centrifuge, is exactly what you want to see.
We ran a flow cytometry validation on MARROW-STEM™, our fenestrated aspiration trocar, using post–iliac crest samples from non-haemopathic, orthopaedic patients. The readout:
✔️ 98% live cells
✔️ MSCs (CD90+CD73+CD105+) at 0.093% of viable cells
✔️ minimal trauma, no centrifugation, and a sample that never leaves the sterile field
Centrifuge-based concentration can discard a meaningful share of cells and growth factors on the way to the pellet. A selective, side-port design keeps the biology where it belongs: in the patient's sample, not in the supernatant.
Sometimes the most telling result is the one that looks small on paper.
