Breakthrough development uses a patient’s own stomach cells, cutting the risk of an immune response to implanted organs. Israeli researchers report that they have invented the first fully personalized tissue implant, engineered from a patient’s own materials and cells. The new technology makes it possible to engineer any kind of tissue implant, for the spinal cord, to the heart, or brain, from one small fatty tissue biopsy. Currently, in tissue engineering for regenerative medicine, cells are isolated from the patient and cultured in biomaterials to assemble into a functional tissue. These biomaterials can be synthetic or natural, derived from plants or animals. After transplantation, they may induce an immune response that leads to rejection of the implanted tissue.
