Multiple myeloma: Tracking down resistant cancer cells

In multiple myeloma, a cancer of the bone marrow, relapse almost always occurs after treatment. Initially, most patients respond well to therapy. However, as the disease progresses, resistant cancer cells spread in the bone marrow, with fatal consequences for the patients. Scientists at the German Cancer Research Center (DKFZ), Heidelberg University Hospital (UKHD) and the National Center for…

Remarkable cartilage regeneration

Joint cartilage usually regenerates very poorly. The matrix of cartilage (scaffolding) contains very few cells in deep layers.
