Additional file 4: Figure S4. of Expression patterns of FSHD-causing DUX4 and myogenic transcription factors PAX3 and PAX7 are spatially distinct in differentiating human stem cell cultures

DUX4 and PAX7 are expressed in distinct cell types during myogenic differentiation of hiPSC-mosaic 1 with the short D4Z4 array. A, B and C) Images of hiPSC-mosaic 1 with the short D4Z4 array from D40 of the differentiation protocol stained with antibodies to both PAX7 and DUX4. Arrows indicate representative DUX4 positive nuclei counted. (DOCX 5052 kb)
