These organoids are typically grown from stem cells and can be used to study diseases, test drug treatments, and even potentially be used for regenerative medicine. By providing a more accurate representation of human biology compared to traditional 2D cell cultures, mini organs allow researchers to better understand organ development, function, and disease mechanisms. **
