Researchers have developed a bioengineered implantable device that generates its own oxygen supply to keep drug-producing cells alive and functional. The technology addresses a key challenge in cell-based therapies by ensuring sustained oxygen delivery to therapeutic cells within the implant.
In animal models, the device maintained cell viability and function for weeks, enabling continuous therapeutic drug delivery. The implant houses drug-producing cells that would normally die without adequate oxygen supply, a common limitation in previous implantable cell therapy approaches.
