KLF13 and non-small cell lung carcinoma: The cell cycle progression (Figure S6C,D) and cell proliferation (Figure S6E,F) were promoted by Exos derived from CAFs, which were weakened by miR‐3126‐5p‐silenced Exos, whereas the suppressive effect of miR‐3126‐5p‐depleted Exos on cell proliferation and cell cycle progression was neutralized by the deficiency of KLF13 in NSCLC cells (Figure S6C–F).
