Abstract

Background: Cord blood (CB) is a useful source of hematopoietic stem cells. In public CB banks, only CB units with good hematopoietic potential are processed and stored because the processing and storage of CB are cost-consuming and labor-intensive procedures. Presently, we sought to determine factors correlated with, and influential to, hematopoietic parameters of CB units donated from Korean neonates and their mothers.
Methods: A total of 1,696 CB units that were donated and processed from August 1 ? December 31, 2007 were enrolled. Donated CB volume, total nucleated cells (TNC), total mononucleated cells (MNC), CD34+ cells after processing, and cell viability before and after processing were analyzed according to sex and delivery method. We also determined whether maternal age, neonatal factors (gestational age, birth weight, sex, delivery method), CB volume, and processing time were correlated with hematopoietic parameters of CB.
Results: CB of female neonates had significantly higher mean TNC and CB obtained from vaginal delivery had significantly higher mean TNC, MNC, and CD34+ cells. The counts of TNC, MNC, and CD34+ cells were significantly positively correlated with CB volume, gestational age, and birth weight. Counts of TNC, MNC, and CD34+ cells, and pre- and post-viability of CB were significantly negatively correlated with processing time.
Conclusion: The present data provide a baseline for standard methods of collection, processing, and storage in cord blood banking.
