In the field of regenerative medicine, intestinal organoids—which are organ-like tissues derived from adult stem cells of the large intestine—have been used to successfully treat ulcerative colitis in mice.1

When these organoids were introduced into the colon of the affected mice, they attached to the damaged tissue. Once attached, they generated a normal-appearing intestinal lining, effectively repairing the injury. These organoids are typically cultivated within a three-dimensional matrix that mimics the extracellular environment, allowing them to replicate specific structural and functional aspects of the organ they represent.123
