title: Immunomagnetic positive selection and colony culture of CD34+ cells from blood.
abstract: Immunomagnetic separation has been used to enrich CD34-positive cells in umbilical cord blood. Cell purities were increased from 0.59% preseparation to 92.7% postseparation (n = 16) with a mean yield of 75.7%. CFU were enriched 127 fold by immunomagnetic separation. Addition of combinations of recombinant growth factors resulted in cloning efficiencies of greater than 50%.
