Hydrogels have been widely investigated in biomedical fields due to their similar physical
and biochemical properties to the extracellular matrix (ECM). Collagen and hyaluronic acid
(HA) are the main components of the ECM in many tissues. As a result, hydrogels prepared
from collagen and HA hold inherent advantages in mimicking the structure and function of
the native ECM. Numerous studies have focused on the development of collagen and HA
hydrogels and their biomedical applications. In this extensive review, we provide a summary …
