Life Biosciences’ gene therapy platform works by inducing expression of the transcription factors Oct3/4, Sox2 and Klfr4, or OSK—three of the four Yamanaka factors. When all four Yamanaka factors are expressed together, have been shown to fully reprogram differentiated human, mouse and primate cells back into pluripotent stem cells, erasing their cell identity and resetting DNA methylation to an embryonic state.
