Early EPCs (CD133+/VEGF-R2+) were also decreased during the first week, and there were no significant differences in their numbers at subsequent days after AIS (CD133+/VEGF-R2+_1 = 0.0099 ± 0.022, CD133+/VEGF-R2+_3 = 0.0049 ± 0.004, and CD133+/VEGF-R2+_7 = 0.0048 ± 0.004; p > 0.05). The gene discussed is PROM1; the disease is androgen insensitivity syndrome.
