High-yield method for extracting hematopoietic stem cells from cord blood

Development of an Innovative Method to Extract Cord Blood Stem Cells With High Efficiency

Observational Fondazione IRCCS Policlinico San Matteo di Pavia · NCT07468201

This research tests whether a new biocompatible liquid, with or without low-dose ozone treatment, can extract more viable hematopoietic stem cells from donated umbilical cord blood than standard centrifugation.

What this trial studies

The project compares traditional centrifugation-based extraction of hematopoietic stem cells (HSCs) from umbilical cord blood with a novel separation technique that uses a biocompatible liquid designed to reduce mechanical stress on cells. Collected cord blood samples will be split and processed by both methods, and some samples will receive low-concentration ozone (2–20 μg/mL, mixed 1:1 with oxygen) to test effects on cell proliferation. Outcomes will include HSC yield, viability, and short-term proliferation metrics measured in the laboratory. All donations are from consenting healthy women and the work is conducted at a single center in Pavia, Lombardy.

Who should consider this trial

Good fit: Healthy women who sign informed consent to donate their newborn's umbilical cord blood for research at the participating hospital.

Not a fit: Women with active viral infections or those unable to comply with protocol requirements are excluded and would not be expected to benefit from participation.

Why it matters

Potential benefit: If successful, the method could increase the number and quality of HSCs obtainable from a single cord blood unit, improving availability for transplants and research.

How similar studies have performed: Mechanical and density-based approaches have previously improved cord blood HSC recovery, but the combination of a biocompatible separating liquid and low-dose ozone is relatively novel with limited prior clinical data.
