Peptide Bioink: Self-Assembling Nanofibrous Scaffolds for Three-Dimensional Organotypic Cultures Yihua Loo Anupama Lakshmanan Ming Ni Lai Ling Toh Shi Wang Charlotte A. E. Hauser 10.1021/acs.nanolett.5b02859.s002 https://acs.figshare.com/articles/media/Peptide_Bioink_Self_Assembling_Nanofibrous_Scaffolds_for_Three_Dimensional_Organotypic_Cultures/2122429 Printable scaffolds with adequate mechanical strength and stiffness are sought after to ensure viability of printed cells and tissues. We report the first peptide bioinks–lysine-containing hexapeptides that self-assemble into stable, nanofibrous three-dimensional hydrogels with unprecedented stiffness of up to 40 kPa. These biocompatible scaffolds support the three-dimensional culture of human stem cells and differentiation of primary cells into organotypic (gastrointestinal and skin) structures for high-throughput screening, diagnosis, and tissue engineering. 2015-10-14 00:00:00 40 kPa biocompatible scaffolds support tissue engineering Peptide Bioink stiffness
