Abstract:

BACKGROUND: As a new type of biomaterial, self-assembling peptide hydrogel is widely used in tissue engineering, drug release, hemostasis and antibacterial agents.

OBJECTIVE: To summarize the hemostatic effect and mechanism of self-assembling peptide hydrogel materials in different bleeding models.
METHODS: Using “self-assembling peptide, hydrogel, hemostasis, trauma” as the key words in Chinese and English, respectively, we retrieved the related literatures published from 2000 to 2018 in PubMed, CNKI, WanFang databases.

RESULTS AND CONCLUSION: Self-assembling peptide materials are characterized as programmability, good viscoelasticity, high biocompatibility and low immunogenicity. The short peptides can self-assemble into nanofiber hydrogels and exhibit good biocompatibility. In different surgical wounds, hydrogels can form physical barriers to exert hemostasis without interacting with the clotting cascade or being coagulated, which can quickly and effectively control bleeding without harm to surrounding tissues or cells. Reasonable use of short peptides that have antibacterial and drug sustained-release properties can ensure rapid hemostatic effect, and meanwhile improve wound microenvironment. Self-assembling peptide hydrogel combined with bioactive molecules to promote wound healing is one of the key research directions of self-assembling short peptide materials at this stage.
