NUTM1 and undifferentiated carcinoma: The discovery of this NMC cell line languishing in a public repository has two implications: (i) it emphasizes the concept that expression of NUTM1 in an undifferentiated carcinoma is diagnostic for NMC, and (ii) it reinforces the fact that NMC has historically been under-diagnosed, highlighting the potential for further discovery of samples in bio-banks around the world.
