Cell recovery comparison between plasma depletion/reduction- and red cell reduction-processing of umbilical cord blood.

Background Aims: Limited cell dose has hampered the use of cord blood transplantation (CBT) in adults. One method of minimizing nucleated cell loss in cord blood (CB) processing is to deplete or reduce plasma but not red blood cells - plasma depletion/reduction (PDR).

Methods: The nucleated cell loss of PDR was studied, and determined to be less than 0.
