Characterization of ex vivo-expanded, cryopreserved pNK cells. a. The fold expansion of primary natural killer (pNK) cells from 4 different donors at 0, 6, 11, 14 days. b. The viability of expanded pNK cells was evaluated using propidium iodide staining. c-d. Identification of key immune NK cells following ex vivo expansion (D14) and cryopreservation (D14 cryo). Percentage of CD3−CD56+, CD56+CD16+, CD3+CD56−, and CD3−CD56− cells (c). CD3+, CD14+, and CD19+ cells from four different donors were analyzed using flow cytometry (d)
