GSK3B and Behcet disease: This impairment was partly reversed by treatment with a selective GSK3β (glycogen synthase kinase 3) inhibitor; moreover, a general differentiation defect of BD iPSCs could be ruled out by NanoString (single-molecule imaging of color-added, molecularly barcoded probes) digital mRNA expression profiling on a panel of “scorecard” genes previously defined to assess quantitatively the differentiation capacity of embryonic stem cells/iPSCs [73].
