In a bid to find or refine laboratory research models for cancer that better compare with what happens in living people, Johns Hopkins Medicine scientists report they have developed a new computer-based technique showing that human cancer cells grown in culture dishes are the least genetically similar to their human sources.
The finding, they say, should help focus more resources on cancer research models such as genetically engineered mice and 3D balls of human tissue known as “tumoroids” to better evaluate human cancer biology and treatments, and the genetic errors responsible for cancer growth and progress.
