Fig 4

(A and B) Short-term CFU assays showing number of colonies formed after 4 h co-cultures of CBSC alone or with rNK cells (A) or aNK cells (B) (N = 13). (C and D) Long-term 4 week cobblestone cultures followed by CFU assays (LTC-IC) showing number of colonies formed after 4 h co-culture of CBSC alone or with rNK cells (C) or aNK cells (D) (N = 8). (E) Cell cycle analysis by flow cytometry of CBSC alone or after co-culture with rNK cells or aNK cells. * P < 0.05, ** P < 0.01.
