What’s in a name? An emerging framework for cancer-associated fibroblasts, myofibroblasts, and fibroblasts

In this issue of Cancer Cell, Foster and colleagues explore the heterogeneity in cancer-associated fibroblasts (CAFs) across tissue types and species, and they identify mechanoresponsive (MR), immunomodulatory (IM), and steady-state-like (SSL) CAFs. They show that altering the relative abundance of these CAF subtypes influences tumor progression and response to anti-tumor therapy.
