1. A method for providing fractions from a whole placental neonatal blood composition, wherein the method provides a white blood cell-enriched fraction and a red blood cell (RBC)-enriched fraction, and optionally a plasma fraction,
wherein the RBC-enriched fraction contains more than one white blood cell, wherein the sum of:
(i) the number of white blood cells in the white blood cell-enriched fraction plus(ii) the number of white blood cells in the RBC-enriched fraction is at least 90% of the total number of white blood cells in the whole placental neonatal blood composition, and wherein the number of white blood cells in the sum is corrected for any samples that are withdrawn for archival or testing purposes, the method comprising: (a) processing the whole placental neonatal blood composition to provide a white blood cell-enriched fraction and a RBC-enriched fraction, using a device that is capable of separating cells into the white blood cell-enriched fraction and the RBC-enriched fraction, and optionally the plasma fraction, (b) cryogenically storing the cells of the white blood cell-enriched fraction and cryogenically storing the cells of the RBC-enriched fraction, and optionally the plasma fraction, (c) wherein the stored cells of the white blood cell-enriched fraction and the stored cells of the RBC-enriched fraction are capable of administration to one recipient, and wherein said administration is capable of transferring into the recipient at least 90% of the white blood cells, that were derived from the whole placental neonatal blood composition. |
