It has been illustrated that MEIS1 silencing in mouse embryonic carcinoma suppressed differentiation in neural cells, while its ectopic expression induced differentiation via expression of neural progenitor markers including GLAST, BLBP, SOX1, and Nestin (Yamada, Urano‐Tashiro, Tanaka, Akiyama, & Tashiro, 2013). Here, MEIS1 is linked to embryonal carcinoma.
