Washington State University has developed a new technology for the development of cells using a bioreactor for cancer therapy. this technique develops cancer-detecting white blood cells (WBC) which supports immunotherapy.

Researchers at Washington State University have created a bioreactor the size of a minifridge that can produce T cells at 95% of their maximal development rate, which is around 30% quicker than what is possible with existing technology. They developed it using T cells from cattle. They expect it will function similarly on human cells.
