A. Timeline of events in the establishment and analysis of M14 and MDA-MB-435. Ref = citation from Reference list; JWCI = John Wayne Cancer Institute.
B. Usage of MDA-MB-435 in journal publications between January 2013 and December 2016 (looking at date of hard copy publication). A search was conducted to look for “MDA-MB-435” in the title or abstract, and available text was examined to classify usage as “breast” or “melanoma”. If authors described MDA-MB-435 more broadly as a cancer cell line, or lack of access to the full text meant that usage could not be determined, usage was classified as “neither/indeterminant”.
