The peptide sequence HAVDIGGGC functions as an N-cadherin mimetic, emulating the cell adhesion properties of the N-cadherin protein's extracellular domain. N-cadherin plays a pivotal role in mediating homophilic cell-cell interactions, particularly during mesenchymal condensation, a critical phase in the development of chondrogenesis and osteogenesis.
Applications and Biological Significance:
-
Tissue Engineering: Incorporating HAVDIGGGC into hydrogels has been shown to enhance mesenchymal stem cell (MSC) chondrogenesis and osteogenesis. These hydrogels promote cell-cell adhesion, resulting in enhanced differentiation outcomes.
-
Cartilage Repair: Hydrogels functionalized with HAVDIGGGC have demonstrated efficacy in promoting cartilage regeneration by facilitating MSC condensation and matrix production.
-
Metabolic Regulation: The presence of HAVDIGGGC in biomaterials has been linked to the modulation of MSC metabolism, balancing glycolysis and fatty acid oxidation, thereby reducing hypertrophy during chondrogenic differentiation.
Overall, HAVDIGGGC serves as a valuable tool in regenerative medicine, aiding in the design of biomaterials that support tissue repair and stem cell differentiation by mimicking natural cell adhesion mechanisms.
