Urine-derived stem cells:applications in skin,bone and articular cartilage repair

As an emerging type of adult stem cell featuring non-invasive acquisition,urine-derived stem cells(USCs)have shown great potential for applications in tissue engineering and regenerative medicine.With a growing amount of research on the topic,the effectiveness of USCs in various disease models has been shown and the underlying mechanisms have also been explored,though many aspects still remain unclear.In this review,we aim to provide an up-to-date overview of the biological characteristics of USCs and their applications in skin,bone and articular cartilage repair.In addition to the identification procedure of USCs,we also summarize current knowledge of the underlying repair mechanisms and application modes of USCs.Potential concerns and perspectives have also been summarized.
