Joint cartilage usually regenerates very poorly. The matrix of cartilage (scaffolding) contains very few cells in deep layers. Moreover, joint cartilage is highly isolated: there are neither regenerative cells in the immediate vicinity that could migrate into the site of the defect and trigger repair, nor vessels that could transport regenerative cells to the cartilage. Unsurprisingly,…
Prostate cancer is one of the most common cancers among men. Patients are determined to have prostate cancer primarily based on PSA, a cancer factor in blood. However, as diagnostic accuracy is as low as 30%, a considerable number of patients undergo additional invasive biopsy and thus suffer from resultant side effects, such as bleeding and pain.
