Engineering monocyte/macrophage−specific glucocerebrosidase expression in human hematopoietic stem cells using genome editing

Abstract

Gaucher disease is a lysosomal storage disorder caused by insufficient glucocerebrosidase expression. Here, the authors describe a CRISPR/Cas9-based gene-editing approach to re-express this enzyme in human blood stem cells and show that they can engraft in NSG mice and differentiate into functional macrophages.
