Flow cytometry was performed using an LSRFortessaTM (Becton Dickinson, Franklin Lakes, NJ, USA) cytometer and FlowJo 10.4 was used to analyze the data.
Antibodies used were: LIFRalpha (FAB5990P; R&D Systems, Minneapolis, MN, USA) and pSTAT3 (557815, Becton Dickinson). Cells were sorted on an Aria IIITM (Becton-Dickinson) as described before [82 (link),83 (link)]. Antibodies used for cell sorting were CD45 (25-0451-82; Thermo Fisher), Ter-119 (116222; Biolegend, San Diego, CA, USA), Gr-1 (108416, Biolegend), CD3 (25-0031-82, Thermo Fisher) and CD11b (25-0112-82, Thermo Fisher). CD31 (102422, Biolegend) Sca-1 (108126, Biolegend), CD166 (12166182, eBioscience, San Diego, CA, USA) and CD140 (135906, Biolegend).
