Fabrication of Homotypic Neural Ribbons as a Multiplex Platform Optimized for Spinal Cord Delivery

Neural ribbons offer multifunctionality in vitro including co-encapsulation of the injury site ESM modifier chondroitinase ABC, tested in glial scar models, and ability of cervically-patterned spinal cord neural stem cells to differentiate within neural ribbons and project axons for integration with 3D external matrices.

Mithramycin Selectively Attenuates DNA-Damage-Induced Neuronal Cell Death

The authors suggested that Sp1 was required for p53-mediated transactivation of neuronal pro-apoptotic molecules and that mithramycin might have attenuated neuronal cell death in conditions predominantly involving DNA-damage-induced p53-dependent intrinsic apoptosis.
