Abstract

Neural tissue engineering holds great potential in addressing current challenges faced by medical therapies employed for the functional recovery of the brain. In this context, self-assembling peptides have gained considerable interest owing to their diverse physicochemical properties, which enable them to closely mimic the biophysical characteristics of the native ECM. Additionally, in contrast to synthetic polymers, which lack inherent biological signaling, peptide-based nanomaterials could be easily designed to present essential biological cues to the cells to promote cellular adhesion. Moreover, injectability of these biomaterials further widens their scope in biomedicine. In this context, hydrogels obtained from short bioactive peptide sequences are of particular interest owing to their facile synthesis and highly tunable properties. In spite of their well-known advantages, the exploration of short peptides for neural tissue engineering is still in its infancy and thus detailed discussion is required to evoke interest in this direction. This review provides a general overview of various bioactive hydrogels derived from short peptide sequences explored for neural tissue engineering. The review also discusses the current challenges in translating the benefits of these hydrogels to clinical practices and presents future perspectives regarding the utilization of these hydrogels for advanced biomedical applications.

Biomaterials Science is an international high impact journal exploring the science of biomaterials and their translation towards clinical use. Its scope encompasses new concepts in biomaterials design, studies into the interaction of biomaterials with the body, and the use of materials to answer fundamental biological questions. Papers do not necessarily need to report a new biomaterial but should provide novel insight into the biological applications of the biomaterial. Articles that primarily focus on demonstrating novel materials chemistry and bring a molecular picture to bear on a given material’s suitability as a biomaterial are more suited to our companion journal, Journal of Materials Chemistry B. Biomaterials Science publishes primary research and review-type articles in the following areas: molecular design of biomaterials, including translation of emerging chemistries to biomaterials science of cells and materials at the nanoscale and microscale materials as model systems for stem cell and human biology materials for tissue engineering and regenerative medicine (Nano)materials and (nano)systems for therapeutic delivery interactions at the biointerface biologically inspired and biomimetic materials, including bio-inspired self-assembly systems and cell-inspired synthetic tools next-generation biomaterials tools and methods
