The invention is directed to methods for accelerating the healing of connective tissue injuries and disorders. In particular, the invention is directed to accelerating the healing of injuries and disorders of tendons and ligaments. Such methods utilize novel compositions including, but not limited to, extraembryonic cytokine-secreting cells (herein referred to as ECS cells), including, but not limited to, Amnion-derived Multipotent Progenitor cells (herein referred to as AMP cells) and conditioned media derived therefrom (herein referred to as Amnion-derived Cellular Cytokine Solution or ACCS), including pooled ACCS, and Physiologic Cytokine Solution (PCS).
