Controlling hydrogelation kinetics by peptide design for three-dimensional encapsulation and injectable delivery of cells.
A peptide-based hydrogelation strategy has been developed that allows homogenous encapsulation and subsequent delivery of C3H10t1/2 mesenchymal stem cells. Structure-based peptide design afforded MAX8, a 20-residue peptide that folds and self-assembles in response to DMEM resulting in mechanically rigid hydrogels. The folding and self-assembly kinetics of MAX8 have been tuned so that when hydro...
متن کاملDipeptide hydrogelation triggered via ultraviolet light.
UV irradiation of a dipeptide gelator in solution with a photoacid generator (PAG) results in the formation of a hydrogel. We demonstrate that photopatterning of these gels using a UV mask is possible.
متن کاملEffects of chain length on oligopeptide hydrogelation.
The co-assembly of mutually complementary, but self-repulsive oligopeptide pairs into viscoelastic hydrogels has been studied. Oligopeptides of 6, 10, and 14 amino acid residues were used to investigate the effects of peptide chain length on the structural and mechanical properties of the resulting hydrogels. Biophysical characterizations, including dynamic rheometry, small-angle X-ray scatteri...
متن کاملSalt-induced hydrogelation of functionalised-dipeptides at high pH.
Addition of divalent cations to a solution of a naphthalene-diphenylalanine that forms worm-like micelles at high pH results in the formation of a rigid, self-supporting hydrogel.
متن کاملNanospheres of doxorubicin as cross-linkers for a supramolecular hydrogelation
In this study, we synthesized a peptide of Nap-GFFYGRGD, which could self-assemble into supramolecular nanofibers. The peptide itself could only form nanofibers but not hydrogels due to the relative weak inter-fiber interactions. The resulting nanofibers were then utilized as the vehicles for anticancer drug doxorubicin. It was found that the nanofibers of Nap-GFFYGRGD could not encapsulate dox...
