Hybrid polymer-peptide conjugates offer the potential for incorporating biological function into synthetic materials. The secondary structure of short helical peptides, however, frequently becomes less stable when expressed independent of longer protein sequences or covalently linked with a conformationally disordered synthetic

In the search for a cell-instructive or cell-interactive artificial extracellular matrix, synthetic hydrogels have been extensively investigated to apply three-dimensional (3D) cell culture and tissue engineering. Here, we are reporting a reverse thermal gelling l/dl-polyalanine block copolymer aqueous solution for

N-Acetylmuramyl-L-Ala-D-Glu-NH2 (muramyl dipeptide) and several of its derivatives are effective immunoactivators that can enhance nonspecific resistance to infection but can also elicit fever. In contrast, one of its stereoisomers, N-acetylmuramyl-D-Ala-D-Glu-NH2, is devoid of both these activities. Our present report demonstrates

As a new application of a thermogel, a poly(ethylene glycol)-b-poly(L-alanine) (PEG-L-PA) gel encapsulating fibroblasts was investigated for wound healing. The fibroblasts were encapsulated by the temperature sensitive sol-to-gel transition of the polymer aqueous solution. Under the in vitro three-dimensional (3D)
