Interestingly though, we recently demonstrated that Transforming Growth Factor‐β (TGF‐β)‐activated normal human lung (NHL) fibroblasts, which are thought to have acquired a myofibroblast‐like phenotype, are softer than normal fibroblasts.[40] Moreover, our in vitro experiments on fibrotic lung cells (LL97A) showed that they are softer than normal lung cells (LL24) (Figure S5A, Supporting Information) and the latter are becoming softer when cultured on stiffer substrates (Figure S5B, Supporting Information). Here, TGFB1 is linked to non-Hodgkin lymphoma.
