Human ESC-Derived Chimeric Mouse Models of Huntington’s Disease Reveal Cell-Intrinsic Defects in Glial Progenitor Cell Differentiation

Huntington's disease (HD) is characterized by hypomyelination and neuronal loss. To assess the basis for myelin loss in HD, we generated bipotential glial progenitor cells (GPCs) from human embryonic stem cells (hESCs) derived from mutant Huntingtin (mHTT) embryos or normal controls and performed RNA sequencing (RNA-seq) to assess mHTT-dependent changes in gene expression. In human GPCs (hGPCs) derived from 3 mHTT hESC lines, transcription...
