PROM1 and androgen insensitivity syndrome: In AIS patients, circulating stem cells (CD133+) were decreased in the first week, but there were no significant differences in their numbers on subsequent days after AIS (CD133+_1 = 0.0325 ± 0.07, CD133+_3 = 0.0177 ± 0.01, and CD133+_7 = 0.0182 ± 0.02; p > 0.05).
