Disease Modeling

Definition

Disease modeling refers to the use of biological systems, often involving stem cells or genetically modified organisms, to replicate and study the mechanisms underlying specific diseases. This approach allows researchers to gain insights into disease progression, test potential treatments, and understand patient-specific responses, making it a vital tool in advancing personalized medicine and therapeutic strategies.
