Abstract

Neural stem cells are emerging as a regenerative therapy for spinal cord injury (SCI), since they differentiate into functional neural cells and secrete beneficial paracrine factors into the damaged microenvironment. Previously, we successfully isolated and cultured adult human multipotent neural cells (ahMNCs) from the temporal lobes of epileptic patients. In this study, we investigated the therapeutic efficacy and treatment mechanism of ahMNCs for SCI using rodent models. When 1 × 106 ahMNCs were transplanted into injured spinal cords at 7 days after contusion, the injection group showed significantly better functional recovery than the control group (media injection after contusion), which was determined by the Basso, Beattie and Bresnahan (BBB) score. Although transplanted ahMNCs disappeared continuously, remained cells expressed differentiated neural cell markers (Tuj1) or astrocyte marker (GFAP) in the injured spinal cords. Moreover, the number of CD31-positive microvessels significantly increased in the injection group than that of the control group. The paracrine pro-angiogenic activities of ahMNCs were confirmed by in vitro tube formation assay and in vivo Matrigel plug assay. Together, these results indicate that ahMN...Continue Reading

Blood Brain Barrier

The blood brain barrier is a border that separates blood from cerebrospinal fluid. Discover the latest search on this highly selective semipermeable membrane here.

Blood Brain Barrier Regulation in Health & Disease

The blood brain barrier is essential in regulating the movement of molecules and substances in and out of the brain. Disruption to the blood brain barrier and changes in permeability allow pathogens and inflammatory molecules to cross the barrier and may play a part in the pathogenesis of neurodegenerative disorders. Here is the latest research in this field.

Blood Brain Barrier Chips

The blood brain barrier (BBB) is comprised of endothelial cells that regulate the influx and outflux of plasma concentrations. Lab-on-a-chip devices allow scientists to model diseases and mechanisms such as the passage of therapeutic antibodies across the BBB. Discover the latest research on BBB chips here.

Astrocytes

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.
