A team of researchers from Spain and Switzerland have developed a new model for studying the development of testicular germ cell tumors by transplanting embryonic stem cells into the seminiferous tubules in mouse models, resulting in the development of testicular germ cell tumors (TGCT) that mimic the early stages of TGCT development. The study, published in Cell Transplantation (20:5), is now freely available on-line. http://medicalxpress.com/news/2011-07-germ-cell-tumors-embryonic-stem.html Cancer Mon, 11 Jul 2011 12:14:41 EST news229605253
