Application and characteristics of self-assembling peptide nanofiber hydrogel in three-dimensional cell culture systems / 中国组织工程研究

ABSTRACT

BACKGROUND:Self-assembling peptide scaffolds have attracted much more attention among three dimensional biomaterials due to its biocompatibility, biodegradation, and tailor-made properties. OBJECTIVE:To review the structure and design of functionalized self-assembling RADA peptide, and the recent advances in the use of RADA self-assembling peptide for three-dimensional cel culture in cel therapy applications. METHODS:Total 224 literatures related to self-assembling peptide and tissue engineering from PubMed, Web of Science and CNKI databases were screened out for this review. The keywords were“self-assembly peptide, tissue engineering”in English and Chinese, respectively. Final y 48 of 224 articles about the design, fictionalization, and three-dimensional cel culture of peptide scaffolds were included in this review. RESULTS AND CONCLUSION:Self-assembling peptide could undergo spontaneous assembly into wel-ordered interwoven nanofibers in water and rapidly form hydrogel, which physical y mimics the architecture of natural extracel ular matrix to ensure a real three-dimensional microenvironment for cel s. In terms of bio-function, this material can be tailor-made with various bioactive short peptide motifs to promote cel adhesion, proliferation, and differentiation.
