Abstract
Purpose of review: Neural stem cells (NSCs) have the potential to proliferate and differentiate into functional neurons, heightening their potential use for therapeutic applications. This review explores bioengineered systems which recapitulate NSC niche cell-cell and cell-matrix interactions.
Recent findings: Delivery of NSCs to the cytotoxic injured brain is limited by low cell survival rates post-transplantation and poor maintenance of native niche bioactive components. The use of biomaterial platforms can mimic in vivo the environment of the two germinal areas of the adult brain in which NSCs thrive. An environmental mimic that includes extracellular proteins and moieties, along with appropriate biomechanical cues has recently demonstrated promising results in enhancing neurogenesis, aiding the production of a bioengineered niche.
Summary: Biocomposition, biomechanics, and biostructure can be manipulated through engineered platforms to re-create the biofunctionality of an NSC niche. Upon transplantation and delivery with biomimetic scaffolds, NSCs show potential to promote functional recovery and rebuild neural circuitry post neurological trauma.
期刊介绍:
The goal of this journal is to publish cutting-edge reviews on subjects pertinent to all aspects of stem cell research, therapy, ethics, commercialization, and policy. We aim to provide incisive, insightful, and balanced contributions from leading experts in each relevant domain that will be of immediate interest to a wide readership of clinicians, basic scientists, and translational investigators.
We accomplish this aim by appointing major authorities to serve as Section Editors in key subject areas across the discipline. Section Editors select topics to be reviewed by leading experts who emphasize recent developments and highlight important papers published over the past year on their topics, in a crisp and readable format. We also provide commentaries from well-known figures in the field, and an Editorial Board of internationally diverse members suggests topics of special interest to their country/region and ensures that topics are current and include emerging research.
