Development and Characterization of Hyaluronic Acid Microgels for Neural Regeneration Applications.

Delivery of therapeutic compounds via biomaterial systems has shown promise for tissue regeneration following central nervous system (CNS) injuries. Stromal cell-derived factor-1a (SDF-1a) modulates progenitor cell recruitment to neural injury sites and may contribute to neural repair. However, SDF-1a has a short half-life and requires a delivery system to both protect and sustain its release.

Stromal Cell-Derived Factor-1a Autocrine/Paracrine Signaling Contributes to Spatiotemporal Gradients in the Brain.

Introduction: Stromal cell derived factor-1a (SDF-1a) and its receptor CXCR4 modulate stem cell recruitment to neural injury sites. SDF-1a gradients originating from injury sites contribute to chemotactic cellular recruitment. To capitalize on this injury-induced cell recruitment, further investigation of SDF-1a/CXCR4 signaling dynamics are warranted.
