Functional assays

Definition

Functional assays are experimental procedures used to evaluate the biological activity or function of cells, tissues, or biomaterials. These assays are crucial in assessing how well a particular treatment or regenerative strategy works, particularly in applications like tissue engineering and therapeutic development. By measuring specific responses or behaviors, functional assays provide valuable insights into the effectiveness of engineered systems and their potential for clinical application.
