Background:

• Tissue engineering (TE) seeks biological substitutes for tissue repair, requiring biomaterials that support cell physiology and tissue maturation.
• The natural extracellular matrix (ECM) dynamically remodels to regulate tissue development.
• Traditional polymer hydrogels have limitations in mimicking the ECM's dynamic and instructive environment.

Purpose of the Study:

• To review the significance of chiral supramolecular hydrogels in tissue engineering.
• To discuss the design principles and external stimuli influencing chiral hydrogel construction.
• To summarize applications and contributions in the field of chiral biomaterials for TE.

Main Methods:

• Review of literature on chiral supramolecular hydrogels for TE.
• Analysis of hydrogel properties, including noncovalent interactions, self-assembly, and biocompatibility.
• Discussion of chiral characteristics' influence on cellular activities (e.g., differentiation, adhesion, proliferation).

Main Results:

• Chiral supramolecular hydrogels exhibit superior potential in TE compared to traditional hydrogels.
• These hydrogels can be constructed under physiological conditions, mimicking the natural ECM.
• Chiral properties are vital for regulating cellular behavior, enhancing tissue formation.
