Neuromics loves to highlight when our reagents are used in meaningful research. Recently, two of our customers published studies using our Tuj-1 mouse monoclonal antibody (MO15013) in their neuroscience research.
The first study looks at various fibrillars that could be used to work with Schwann cells (SCs) and dorsal root ganglia (DRG) in tissue engineering applications. They aim to assess the differences in biological behavior of the SCs and DRG when interacting with electrospun nanofibers and extruded microfibres. With our Tuj-1 antibody, they find that the extruded microfibers produce higher motility and cell-cell interaction, while a higher cell-material interaction with a lower cell motility is observed for the electrospun nanofibers. As a result, the authors conclude that there is more potential for axonal growth with the extruded microfibers when compared to the electrospun nanofibers.

The second publication explores Glucose Synthase Kinase-3 (GSK-3) inhibition, and how it could lead to neurogenesis as a potential treatment for spinal cord injuries. When culturing various types and species of multipotent stem cells in vitro and inhibiting GSK-3, they found an increased number of neurons. Our Tuj-1 (MO15013) mouse monoclonal antibody was used to help recognize this increase in neurons around the site of injury. In the future, the combination of treating animals with ependymal stem/progenitor cells, human embryonic stem cells–derived neural progenitors, and a GSK-3 inhibitor could be a viable treatment for spinal cord injuries with further supporting research.
