Abstract

Two recent papers (one by Román-Rodríguez et al., 2019 in this issue of Cell Stem Cell) highlight how the power of biological selection on hematopoietic stem cell fitness can facilitate gene therapies for Fanconi Anemia. A clinical trial using lentiviral gene replacement and a proof-of-concept targeted genome editing study show robust engraftment and expansion of gene-corrected cells at levels reaching therapeutic relevance.
