Mechanically and chemically defined hydrogel matrices for patient-derived colorectal tumor organoid culture.

abstract：:Nitric oxide (NO) possesses various functions in cardiovascular diseases; however, due to an extremely short half-life and low bioavailability, its therapeutic application is limited. In inflamed tissues, overproduced reactive oxygen species (ROS) rapidly react with the endogenous NO, reducing its bioavailability. Her...
