The colorectal carcinoma cell lines Colo205 (obtained from Dr. Eva Szegezdi) and HT-29 (ATCC, Manassas, VA, USA) were cultured in RPMI (Lonza, Basel, Switzerland) and in McCoy’s 5A (Lonza), respectively. HEK293 cells were grown in DMEM (Lonza) and CHO cells (ATCC) in Ham’s F12. The prostate cancer cell lines, LNCaP (ATCC), C4-2B (obtained from Dr. Wafa Al-Jamal) and PC3 (ATCC), were cultured in RPMI medium (Lonza). All media were supplemented with 10% fetal bovine serum (FBS) (Thermo Fisher Scientific, Waltham, MA, USA), 100 U/mL penicillin and 100 μg/mL streptomycin.
Human bone marrow derived MSCs were from Lonza, human adipose derived stem cells were from Amsbio (Cambridge, MA, USA) and human umbilical cord derived MSCs were from Promocell (Heidelberg, Germany). The different human MSCs were cultured in StemMACS MSC Expansion Medium (Miltenyi Biotec, Bergisch Gladbach, Germany). Murine MSCs were isolated and cultured as previously described [75 (link)]. In experiments where it was stated that MSCs were used, but not further defined, human bone marrow derived MSCs were used.
