Analysis of specific gene expressions related to chromatin regulation (Dnmt1, Hist1h2br), cell growth (Ppan), tip identity (Wnt11), cellular metabolism (Acot7, Adsl), and RTK signaling targets (Wnt11, Etv4) in isolated UB and MM populations confirmed the DEGs identified in RNA-seq (Additional file 1: Fig. S3B,C). This evidence concerns the gene ETV4 and Miyoshi myopathy.
