These results showing that Müller cells lose their glial property via the TGF-β1-SNAIL axis, in concert with myofibroblastic phenotypes obtained under the Type 2 EMT program (Figs 2–4), led us to propose the nomenclature “Müller GMT”, which should be distinctly discriminated from Type 3 EMT (carcinogenesis)-mimicking GMT in glioblastoma cells of brain astroglial origin23–25. The gene discussed is SNAI1; the disease is glioblastoma.
