Total RNA was prepared from DsRed+ cells, DsRed+ cells allowed to undergo myogenic differentiation for 5 days, DECT+ cells, and DECT+ cells allowed to undergo myogenic differentiation for 5 days. RNA was isolated using TRIzol Reagent (Invitrogen, Carlsbad, CA, USA) and purified as previously described (Ozawa and Kobayashi, 2014 (link)). cRNA was amplified and labeled using a Quick Amp Labeling Kit (Agilent Technologies, Santa Clara, CA, USA) and hybridized to a 44K Agilent 60-mer oligomicroarray (Mouse Oligo Microarray Kit). The hybridized microarray slides were scanned using an Agilent scanner. The relative hybridization intensities and background hybridization values were calculated using Agilent Feature Extraction Software (version 9.5.1.1). Microarray data analysis was supported by Cell Innovator (Fukuoka, Japan).
