I have written previously about the not-so-distant possibility and promise of regenerative medicine, an area concerned with therapies that encourage the body to repair or heal itself. Cell-mediated and tissue-based technologies hold promise in inducing self-repair from within the body, and they’re making their way to market in traditional medicine. Much has been made of recently discussed CAR-T cell therapies for cancer, which have been around since 2017, and in-human sickle cell treatment Casgevy. Such applications of regenerative medicine and tissue engineering are wide-spanning and range across the bench-to-bedside pathway.
One application of regenerative medicine gaining some ground in the R&D space is the organoid. Organoids are lab-grown masses of cells and tissue that assemble to form miniature organs or organ systems in vitro. They come, too, in different forms and types, and while some organoid applications are heavily modified for specific functions, many are meant to recreate and model the naturally occurring organ systems we would find in our own bodies.
Organoids may sound especially futuristic, but are currently used regularly in labs for different research and therapeutic applications. A functional “organ” model not attached to a human body could offer the opportunity to model diseases and test treatments in real time without the need for an animal model (like the mice used today), especially in preclinical and early clinical trials for new drugs. Organoids generate information and data, and a single organoid model can even be hooked up to a “system” with other organoids to model systems and interrelated processes at once. The production of these models occurs in-lab, often involving stem cells that can divide and organize into tissues and organs on their own.
