abstract = {Transgenes are often silenced upon differentiation of
pluripotent stem cells using conventional expression
systems. Here, we developed the TK4 PiggyBac vector to
conduct a comparative analysis to evaluate the impact of
various promoters, transcriptional regulatory elements,
insulators, and genomic integration sites on transgene
silencing during neuronal differentiation. Our findings
reveal that specific combinations of CAG and Ubc promoters
with the Woodchuck hepatitis virus post-transcriptional
regulatory element (WPRE) can prevent transgene silencing
during differentiation, whereas chromatin insulators have
less impact on sustained expression. Three novel safe harbor
loci, distant from known genes, as well as the citrate lyase
beta-like (CLYBL) locus, similarly support the prevention of
transgene silencing. Remarkably, the TK4 vector showed
complete resistance to silencing across various neuronal and
microglial differentiation protocols, as independently
confirmed by seven laboratories. This construct will be
highly useful for assays requiring stable transgene
expression during differentiation and holds potential for
broad applications in various research fields.},
