Cell-Based Therapy Of Human Adipose- Derived Mesenchymal Stem Cell Expressing Angiopoietin-1 In An Experimental Model Of Airway Inflammation
Cell-based therapy of mesenchymal stem cells (MSCs) has been shown to enhance the endogenous repair process by increasing the limited regenerative capacity of the lung in chronic lung disorders as well as following injury. However, the underlying cellular and molecular mechanisms of MSCs to enhance...
