Number of human prostate glands generated per recombinant and recombinant survival rate of recombinants grafted. A. The percentage of recombinants with human ductal growth in the first generation ALDHHi n = 42 and ALDHLow n = 41, analyzed by Fisher’s Exact test P = 0.4692. B. The number of glands per recombinant in the first generation derived from ALDHHi cells (n = 6) and ALDHLow (n = 5) was quantitated and analyzed by unpaired t-test analysis P = 0.2558. C. Kaplan-Meier plot of recombinant survival rate in multiple generations, Logrank test P = 0.3890.
