It is composed of protein complexes synthesized by cells and secreted extracellularly. It exists in tissues and maintains the extracellular microenvironment and is not any cell. Common ingredients include collagen, fibronectin, laminin, etc.
The components of the extracellular matrix determine the characteristics of the tissue, regulate cell development and cell physiological activities, and play an important role in maintaining cell morphology and function.
This Matrix is ​​of human origin and can reduce the impact of cells on external stimuli. It also provides different cell matrices for different cells, assisting various stem cells and other difficult-to-culture cells to expand and differentiate in large quantities (Ex: cartilage/nerve/vascular cells).
