All-iPS cell mice generated from terminally differentiated B cells

ABSTRACT: The generation of induced pluripotent stem cells (iPSCs) often results in aberrant silencing of the imprinted Dlk1-Dio3 gene cluster, which compromises their ability to generate entirely iPSC-derived mice (“all-iPSC mice”). Here, we show that reprogramming in the presence of ascorbic acid attenuates hypermethylation of Dlk1-Dio3 by enabling a chromatin configuration at its imprint control region that interferes with abnormal binding of the DNA methyltransferase Dnmt3a. This approach allowed us to generate adult all-iPSC mice from mature B cells, which have thus far failed to support the development of exclusively iPSC-derived postnatal mice. Our data demonstrate that factor-mediated reprogramming can endow a defined, terminally differentiated cell type with a developmental potential eq
