Quality Matters


Get the Most out of Your Cord Blood

The quantity and viability of stem cells extracted from cord blood units are critical parameters for a successful transplantation. Progenics consistently yields a high average of 98% of Total Nucleated Cells (TNCs) from all cord blood units processed between the year of 2014-2018 (Graph on the left).

What is Yield of TNC?

The percentage yield of TNC indicates the processing quality for each sample and the yield of the number of  TNC per milliliter represents the processing quality of a cord blood bank. Therefore, the accuracy of percentage yield must be supported by the yield per milliliter. At Progenics, the average yield (%) and the yield per milliliter on all cord blood units that are banked at our facility. This distinguishes Progenics’ results from claims made by most other cord blood banks. In addition, our quality has been published in a peer-reviewed journal (Yang H et al, Transfusion (2011) 51;284-292).

This formula can be applied to indicate processing quality regardless of processing methods! Simply put, higher yield equals higher quality. However, it should also be supported by the yield of cells per milliliter from processing.


Higher Viability of Stem Cells

It has been supported that a shorter time between collection and processing is a critical factor that affects banking quality (Pope B., et al Transfusion 2012), this ensures that cells processed will have a higher viability. At Progenics, the average time from cord blood collection to processing is 17 hours.

Certificate of Cryopreservation

A Certificate of cryopreservation that includes important quality indicators will be issued to the parents.

The Certificate of Cryopreservation contains the date that the cord blood was successfully processed and cryopreserved,  processing results including the cord blood volume that was collected, the yield of TNC (%), and the number of total nucleated cells (TNC) banked for transplantation.
