Where this comes from

Abstract

The ability to transplant immunologically foreign cells into an animal without immune suppression would be transformative. Pavan et al. show that human pluripotent stem cell-derived dopaminergic neuron progenitors engineered to express eight immune-evasive proteins can engraft in humanized mice and a rat model of Parkinson's disease without recourse to immune suppression.<sup>1</sup>.
