MREG and viral infectious disease: (A) t-SNE analysis of single cells (n = 56) for Ad-tdTomato (n = 34) and Ad-tdTomato-Atoh1(n = 22) infected supporting cells using MATLAB. (B) Box-plot for verified hair cell specific genes, including hair cell genes that are not induced by Atoh1 virus infection (Mcoln3, Fscn2) and hair cell genes that are induced by Atoh1 virus infection (Chrna10, Mgat5b, Mreg, Rab15).
