摘要

The adult brain has a very limited regeneration capacity and there is no effective treatment currently available for brain injury. Neuroprotective drugs aim to reduce the intensity of cell degeneration but do not trigger tissue regeneration. Cell replacement therapy is a novel strategy to overcome brain injury-induced disability. To enhance cell viability and neuronal differentiation, developing bioactive scaffolds combined with stem cells for transplantation is a crucial approach in brain tissue engineering. Cell interactions with the extracellular matrix (ECM) play a vital role in neuronal cell survival, neurite outgrowth, attachment, migration, differentiation, and proliferation. Thus, appropriate cell-ECM interactions are essential when designing and modifying scaffolds for application in neural tissue engineering. To improve cell-ECM interactions, scaffolds can be modified with bioactive peptides. Here, we discuss the characteristic features of laminin-derived Ile-Lys-Val-Ala-Val (IKVAV) sequence as a bio-functional motif in scaffolds and the behavior of stem cells in scaffolds conjugated with the IKVAV peptide. The incorporation of this bioactive peptide in nanofiber scaffolds markedly improves stem cell behavior and may be a potential method for cell replacement therapy in traumatic brain injury.
