  • Publication number: 20220354473
    Abstract: Methods are disclosed for dissecting a mucosa and a submucosa from a muscularis propria from a region of an organ of a subject, wherein the organ is not the esophagus. In some embodiments, the organ is in the gastrointestinal tract. These methods include injecting submucosally into the organ of the subject a pharmaceutical composition comprising an extracellular matrix (ECM) hydrogel to form a cushion between the submucosa and the underlying muscularis propria at the region of the organ, wherein the ECM hydrogel has the following characteristics: a) a time to 50% gelation of less than 30 minutes at a temperature of about 37° C.; b) a flow viscosity suitable for infusion into the organ; and c) a stiffness of about 10 to about 400 Pascal (Pa).
