Comparison of prefreeze vs postthaw cell counts to demonstrate the correlation between bank and MSKCC measurements and the postthaw recovery. (A) Comparison of prefreeze CD34⁺ cell count reported by the bank with the postthaw CD34⁺ cell count measured at MSKCC. The MSKCC total CD34⁺ cell counts are shown (not adjusted for postthaw viability). The line of best fit is shown as a dashed line. CB units in the shaded region had <100% recovery postthaw. Red stars represent CB units with postthaw CD34⁺ cell viability <75%. (B) Comparison of prefreeze TNC count reported by the bank and the postthaw TNC count measured at MSKCC. The correlation between bank and postthaw MSKCC TNC count is stronger than for CD34⁺ cell count.
