Excerpts from the paper: "The potential to combine elastic Cnidoin and rigid CPP-1 proteins was a promising strategy to design new biomaterials capable of forming stable structures with spontaneous crosslinking to realize outstanding flexibility and toughness, similar to biological nematocyst capsules. Synthetic bioinspired protein nanofibers have gained increasing attention as an artificial matrix to culture stem cells for tissue engineering applications." "In the present work, Bentele et al. introduced a new class of synthetic crosslinker-free nanofibers based on the Hydra nematocyst proteins CPP-1 and Cnidoin using electrospinning. Based on the spontaneous crosslinking capacity of CRDs they systematically optimized the preparative conditions to bioengineer crosslinker-free protein nanofibers that are stable under water with potential applications for human stem cell culture. The research team obtained representative immunofluorescence images of a Hydra conjugated with CPP-1 (green) and Cnidoin (red) antibodies to co-localize the proteins in the capsule wall.
