In fragile X syndrome (FXS) embryos FMRP is widely expressed during early stages of embryogenesis however it is inactivated by the end of the first trimester. In the same manner, human embryonic stem cell (hESC) lines from FXS blastocysts, bearing the full CGG expansion mutation, express FMRP in their pluripotent stage and in neurons derived following in vitro differentiation, FMR1 is completely silenced. Therefore, in vitro neural differentiation of FX-hESC lines serves as a uniquely valuable model system to study the developmental mechanisms underlying FXS, together with the proper differentiation protocol to mimic the neurodevelopmental process occurs in vivo.
