In 1998, Dr. Sangeeta Bhatia, a renowned biomedical engineer, revolutionized the field of biotechnology by developing a method to grow liver cells outside the human body using microfabrication techniques. This pioneering approach enabled significant advancements in medical research, notably in drug toxicity testing and regenerative medicine. By creating artificial environments conducive to liver cell growth, Dr. Bhatia's work established novel methodologies in diagnostics and therapeutic solutions, propelling future innovations in medical science.
