abstract = {Recent reports suggest that induced neurons (iNs), but not
induced pluripotent stem cell (iPSC)-derived neurons,
largely preserve age-associated traits. Here, we report on
the extent of preserved epigenetic and transcriptional aging
signatures in directly converted induced neural stem cells
(iNSCs). Employing restricted and integration-free
expression of SOX2 and c-MYC, we generated a fully
functional, bona fide NSC population from adult blood cells
that remains highly responsive to regional patterning cues.
Upon conversion, low passage iNSCs display a profound loss
of age-related DNA methylation signatures, which further
erode across extended passaging, thereby approximating the
DNA methylation age of isogenic iPSC-derived neural
precursors. This epigenetic rejuvenation is accompanied by a
lack of age-associated transcriptional signatures and
absence of cellular aging hallmarks. We find iNSCs to be
competent for modeling pathological protein aggregation and
for neurotransplantation, depicting blood-to-NSC conversion
as a rapid alternative route for both disease modeling and
neuroregeneration.},
