The frequency of CD13 and CD33 expression within the CD34+CD38− fraction increases during ex vivo culture (n = 2).
Uncultured (day 0) or ex vivo–cultured (days one to 4) cells were labeled with anti-CD34-PerCP, anti-CD38-FITC, and one of anti-CD13-PE or anti-CD33-PE, and analyzed by flow cytometry.
