Secondary colonies formation as derived from LTBMC initiated with purified CD34+ cells exposed to HIV-1 and HIV-2. CFC are expressed as percentage of control cultures performed with heat inactivated virus for each time point. All cultures were performed in duplicate. The control CFC per 105 cells were 2,890 ± 310, 128 ± 22, and 26 ± 6 for 1, 3, and 5 weeks, respectively.
