Generation of a heterozygous GAPDH-Luciferase human ESC line (HVRDe008-A-1) for in vivo monitoring of stem cells and their differentiated progeny

Human stem cell-derived beta (SC-β) cells are a candidate for cell replacement therapy for type 1 diabetes. Whilst refinements to the differentiation protocol have resulted in the production of SC-β cells that resemble adult beta cells, the unsolved challenge to protect transplanted SC-β cells from the host immune system remains. To monitor the survival of SC-β cells in vivo, we knocked-in the Firefly luciferase gene into the GAPDH locus of the HUES8 human embryonic stem cell (hESC) line, such that differentiated islet cells constitutively express luciferase.
