In this case, the 'in mice' tag may be a plus - getting a xenograft to take in immunocompetent hosts is a high bar.

'We report the editing of primary human islet cells to the hypoimmune HLA class I– and class II–negative and CD47-overexpressing phenotype and their reaggregation into human HIP pseudoislets (p-islets). Human HIP p-islets were shown to survive, engraft, and ameliorate diabetes in immunocompetent, allogeneic, diabetic humanized mice'
