Expression levels of pluripotency markers in T47D cells after APRIL or BAFF treatment. (A) Expression levels of ALDH1A1, KLF4, SOX-2, and c-MYC, genes (quantified by Real-Time PCR and expressed as percentage of control) after treatment of T47D cells with APRIL or BAFF (100 ng/ml) for 4 days. Three independent experiments were performed (mean ± SE, *denotes p < 0.05, at least). (B,C) Expression of SOX-2, c-MYC, ALDH1A1, and NANOG proteins (assayed by immunocytochemistry). Representative images of three independent experiments are presented (B) Quantification of the proteins' expression levels was performed in at least 10 cells in three different photos for both control and treated cells using Image J and is expressed as percentage of control (mean ± SE, (C)).
