Imprinting fidelity in mouse iPSCs depends on sex of donor cell and medium formulation

Abstract

Reprogramming somatic cells to induced pluripotent stem cells (iPSCs) is associated with epigenetic alterations. Here the authors assess DNA methylation in detail in multiple female and male mouse iPSC lines generated with different protocols and find that defects depend on the sex of donor cells and can be partially mitigated by Vitamin C.
