Interestingly, it was found that RD cells of smooth muscle rhabdomyosarcoma origin [7] displayed relatively high expression of both early neural differentiation markers: (PAX6, Musashi1, & βIII-tubulin (Fig. 2a), as well as the mature neural differentiation markers NCAM and NSE (Fig. 2b). Here, ENO2 is linked to rhabdomyosarcoma.
