An NMuMG-derived TGFβ signature accurately and quantitatively predicts TGFβ pathway activation. (a) Principal component analysis (PCA) of untreated NMuMG cells (open circles), TGF-β1 treated cells (training set, filled squares), and TGF-β3 treated cells (testing set, filled circles). (b) SVD regression demonstrating quantitative prediction of TGFβ pathway activity in both TGF-β1 and TGF-β3 treated cells.
