Figure Lengend Snippet: ( A ) Results of MTT assays in wt and TDG-null ECCs treated with increasing concentrations of RA for neurectodermal differentiation or with 1% DMSO for mesodermal differentiation. ( B ) Immunofluorescence detection of the neural marker PAX6 and the cardiomyocyte marker ACTA2 in untreated ECCs (top) and wt (middle) and TDG-null (bottom) cells treated for 72 hours with 1 μM RA. Cells were counterstained with DAPI. ( C ) Phase-contrast microscopy images of wt and TDG- null ECCs treated with 1 μM RA for 6 days. Cells were first grown as embryoid bodies for 2 days and then re-plated in cell-culture dishes for 4 days. ( D ) Quantification of neurite extension from embryoid bodies 4 days after replating. ( E ) RT-qPCR assay of Meis1 mRNA levels in wt and TDG-null ECCs treated with increasing concentrations of RA or 1% DMSO for 48 hours. ( F ) Phase-contrast microscopy images of wt and TDG-null ECCs grown as monolayers and treated with increasing concentrations of RA or with 1% DMSO. White triangles point to regions of RA-induced 3D growth. ( G ) Quantification of 3D growth regions in wt, TDG-null and two clones of Cyp26a1-null ECCs. ( H ) RT-qPCR assay of the pluripotency marker Oct4 , the neural marker Pax6 , and the cardiomyocyte marker Acta2 mRNAs in the indicated cells treated or not with 1 μM RA for 48 hours. ( I ) RT-qPCR assay of Bdnf mRNA in the indicated cells treated or not with 1 μM RA for 48 hours. ( J ) RT-qPCR assay of Tdg mRNA in the indicated cells treated or not with 1 μM RA for 48 hours. ( K ) Western blot detection of TDG in wt, TDG-null, and Cyp26a1-null ECCs. Detection of U2AF65 serves as a loading control. Arrowheads indicate TDG bands and the asterisk indicates a non-specific band. ( L ) RT-qPCR assays for the indicated ATF4/ISR pathway genes in cells treated or not with 1 μM RA for 48 hours.
