Human somatic cell mutagenesis creates genetically tractable sarcomas.

Creating spontaneous yet genetically tractable human tumors from normal cells presents a fundamental challenge. Here we combined retroviral and transposon insertional mutagenesis to enable cancer gene discovery starting with human primary cells. We used lentiviruses to seed gain- and loss-of-function gene disruption elements, which were further deployed by Sleeping Beauty transposons throughout the genome of human bone explant mesenchymal cells.
