Abstract
Abstract: The addition of mitogen-prestimulated periferal blood lymphocytes (PBL) or Epstein-Barr virus (EBV)-transformed lymphoblastoid cell lines (LCL) cultures to enriched populations of natural killer (NK) cells obtained from PBL of normal donors in the presence of rIL-2 resulted in highly significant increases in proliferation, purity, and cytolytic activity of cultured NK cells. Two sources of enriched NK cell preparations were used: (i) Adherent-lymphokine activated killer (A-LAK) cells obtained by adherence to plastic during 24 hr activation with 103 Cetus U/ml rIL-2; and (ii) NK cells negatively selected from PBL by removal of high-affinity rosette-forming cells and CD3+ lymphocytes. Coculture of A-LAK cells for 14 days with autologous or allogeneic Con A-activated PBL (106 cells/ml) or selected EBV-transformed LCL (2 × 105 cells/ml) as feeder cells increased fold expansion by a mean ± SEM of 629 fold ± 275 (P < 0.019) and 267 fold ± 54 (P < 0.0001), respectively, compared to 55 ± 20 in A-LAK cultures without feeder cells. The addition of either activated PBL or EBV lines to A-LAK cultures also led to a significant increase in the percentage of NK cells (CD3−CD56+) (84 ± 2.4 and 84 ± 2.6%, respectively, P < 0.0001 for both), compared to 53 ± 7.2% in cultures without feeders. The presence of feeder cells in cultures of A-LAK cells also led to significantly higher anti-tumor cytolytic activity compared to control cultures, as measured against NK-sensitive (K562) and NK-resistant (Daudi) target cells. Mitogen-stimulated CD4+ PBL purified by positive selection on antibody-coated flasks were better feeders than CD8+ or unseparated PBL. In the presence of feeder cells, it was possible to generate up to 6 × 109 activated NK cells from 2 × 108 fresh PBL by Day 13 of culture. Enhanced NK cell proliferation in the presence of feeder cells was not attributable to a detectable soluble factor. The improved method for generating A-LAK or activated-NK cells should facilitate cellular adoptive immunotherapy by providing sufficient numbers of highly enriched CD3−CD56+ effector cells with high anti-tumor activity.

<abstract xml:lang="en"><p>The addition of mitogen-prestimulated periferal blood lymphocytes (PBL) or Epstein-Barr virus (EBV)-transformed lymphoblastoid cell lines (LCL) cultures to enriched populations of natural killer (NK) cells obtained from PBL of normal donors in the presence of rIL-2 resulted in highly significant increases in proliferation, purity, and cytolytic activity of cultured NK cells. Two sources of enriched NK cell preparations were used: (i) Adherent-lymphokine activated killer (A-LAK) cells obtained by adherence to plastic during 24 hr activation with 103 Cetus U/ml rIL-2; and (ii) NK cells negatively selected from PBL by removal of high-affinity rosette-forming cells and CD3+ lymphocytes. Coculture of A-LAK cells for 14 days with autologous or allogeneic Con A-activated PBL (106 cells/ml) or selected EBV-transformed LCL (2 × 105 cells/ml) as feeder cells increased fold expansion by a mean ± SEM of 629 fold ± 275 (P < 0.019) and 267 fold ± 54 (P < 0.0001), respectively, compared to 55 ± 20 in A-LAK cultures without feeder cells. The addition of either activated PBL or EBV lines to A-LAK cultures also led to a significant increase in the percentage of NK cells (CD3−CD56+) (84 ± 2.4 and 84 ± 2.6%, respectively, P < 0.0001 for both), compared to 53 ± 7.2% in cultures without feeders. The presence of feeder cells in cultures of A-LAK cells also led to significantly higher anti-tumor cytolytic activity compared to control cultures, as measured against NK-sensitive (K562) and NK-resistant (Daudi) target cells. Mitogen-stimulated CD4+ PBL purified by positive selection on antibody-coated flasks were better feeders than CD8+ or unseparated PBL. In the presence of feeder cells, it was possible to generate up to 6 × 109 activated NK cells from 2 × 108 fresh PBL by Day 13 of culture. Enhanced NK cell proliferation in the presence of feeder cells was not attributable to a detectable soluble factor. The improved method for generating A-LAK or activated-NK cells should facilitate cellular adoptive immunotherapy by providing sufficient numbers of highly enriched CD3−CD56+ effector cells with high anti-tumor activity.</p>
