1 Upstate Cord Blood Bank

2 Hematopoietic Progenitor Cells Hematopoiesis i starts from self renewing HPC HPC differentiates t to sequentially more mature blood cells HPC circulate in very low numbers in adults (< 0.01%)

3 Collection of Cord Blood Cord Blood Stem Cells Collected from umbilical vein of placenta soon after birth Collect ml total volume 1.25 x 10 6 CD34+ cells Normally disposed of as medical waste cbcollection2.jpg

4 Processing of Cord Cells Cord blood is aseptically yprocessed Stem cells recovered in freezing bag while RBC and plasma separated tdduring automated t processing Cells in RBC bag are retained for DNA isolation and testing for hemoglobinopathies Aliquots of plasma retained per FACT, FDA, and NMDP regulations

5 Processing of Cord Cells Cord blood is aseptically yprocessed Total volume measured Samples removed to measure: Total number of nucleated cells % of nucleated cells CD34+ Bacterial contamination Additional samples stored for future testing

6 Processing of Cord Cells Cord blood must be frozen to prevent apoptosis and senescence of cells Liquid nitrogen Freezing results in ice crystal formation causing cell lysis DMSO is added in sterile conditions to stabilize cells

7 Upstate Cord Blood Bank

8 Upstate Cord Blood Bank Separate manufacturing zones in order to maintain cord blood safety

9 Upstate Cord Blood Bank Opening Summer 2016

10 FDA Regulation of a Cord Blood Bank (Tissue Bank) FDA regulation of a GxP facility (regulated as a drug and as a biologic) FDA regulates hematopoietic stem/progenitor cells for unrelated use as a DRUG under FD&C Act and as a BIOLOGICAL PRODUCT under the PHS Act.
