Artificial lung the size of a sugar cube
What medications can be used to treat lung cancer, and how effective are they? Until now, drug companies have had to rely on animal testing to find out. But in the future, a new 3D model lung is set to achieve more precise results and ultimately minimize – or even completely replace – animal testing. From June 23-26, researchers will …
Competition among cells prevents cancer
T lymphocytes arise from the thymus gland, which plays an important role in the immune system. In this organ, immature progenitor cells originating in the bone marrow mature into immune system cells. The bone marrow constantly produces new progenitor cells that migrate into the thymus, where they replace older, „worn-out“ progenitors. Scientists at the German Cancer Research Center (Deutsches Krebsforschungszentrum, …
What the long-lived naked mole rat teaches us about cancer resistance
Scientists can learn a lot from naked mole rats, as these little rodents don’t show any symptoms of old age despite their long life expectancy. During several decades of research on naked mole rats no case of cancer development was reported. Scientists now found out what might confer cancer resistance to these rodents.
