Additional file 1 of A hybrid epithelial-mesenchymal transition program enables basal epithelial cells to bypass stress-induced stasis and contributes to a metaplastic breast cancer progenitor state

Supplementary Material 1: Table S1 Quantitative proteomic analysis of conditioned media from HMECs using antibody array. Quantitative proteomic analysis was performed using the Quantibody array-based multiplex ELISA system to simultaneously quantify 1000 protein targets, including cytokines, growth factors, proteases, soluble receptors, and other proteins. Conditioned media (CM) were collected from three different donors: passage 2 (P2) HMECs, stasis HMECs (S), and variant HMECs at two passages beyond stasis (S+2). The table presents the expression levels of the analyzed proteins in pg/mL. An unpaired t-test with Welch's correction was performed on each row of the dataset. Following this, a two-stage linear step-up procedure (Benjamini, Krieger, and Yekutieli) was applied to control the False Discovery Rate (FDR) and adjust for multiple comparisons.
