Described herein are compounds of Formula I, or pharmaceutically acceptable salts thereof, or combinations thereof, as well as uses thereof. Such uses include promoting tissue self-repair or tissue regeneration of an organ, stimulating the generation of tissue growth, modulating (e.g., increasing) the level of a tissue-repair marker, treating physical injury in an organ, tissue or cell, promoting wound healing, as well as anti-aging applications. Corresponding compositions, methods, kits, and uses are also described.
