Potential mesenchymal stem cell therapy for skin diseases.

Mesenchymal stem cells (MSCs) are non-haematopoietic cells that reside in most tissues including adult bone marrow. MSCs have recently been extensively studied and used for clinical therapies, including skin wound healing. However, there are still many questions to be answered. In the viewpoint entitled 'Mesenchymal stem cell therapy in skin: why and what for?', Dr. Khosrotehrani provided a comprehensive overview for MSC properties and current progresses on clinical applications for various skin conditions. This viewpoint is therefore very helpful for both dermatologists and basic skin researchers to understand stem cells researches.
