A new five - year canine cancer research project, led by Dr. Liz Pluhar, may improve survival rates in dogs and give researchers more insight
into glioblastoma to apply to human trials.
Testing each of these factors for their ability to return differentiated tumor cells to a stem - like state, identified a combination of four — POU3F2, SOX2, SALL2 and OLIG2 — that was able to reprogram differentiated tumor cells back
into glioblastoma stem cells, both in vitro and in an animal model.
Shah and his team loaded the herpes virus into human MSCs and injected the cells
into glioblastoma tumors developed in mice.
In 2009 he had been diagnosed with a type of rapidly growing brain tumor called a high - grade astrocytoma that, despite aggressive treatment, eventually evolved
into a glioblastoma — the highly malignant brain tumor that also took the lives of Vice President Joe Biden's son, Beau, in 2015 and former Sen. Ted Kennedy in 2009.

Another is that the transplanted bits of tumor act nothing like cancers in actual human brains, Fine and colleagues reported in 2006: Real - life
glioblastomas grow and spread and resist treatment because they contain what are called tumor stem cells, but tumor stem cells don't grow well in the lab, so they don't get transplanted
into those mouse brains.

The findings may even have implications for studying
glioblastoma, a common brain cancer whose ability to grow, migrate and hack
into the brain's blood supply appears to rely on a pattern of gene activity similar to that now identified in these neural stem cells.
