FUT4 and testicular germ cell tumor: Although rare overall, testicular germ cell tumors are most common in young men and survival rates were very poor until the inclusion of cis‐platinum into therapy dramatically changed the outcomes.[7] We all decided our experience and interests overlapped sufficiently, so I moved to Wistar to delve more into characterizing the structure of the SSEA1 antigenic determinant[8] and to try to identify undifferentiated EC cells in the germ cell tumor cell lines, and find evidence that they differentiated in culture.
