Growing the Distance

Spinal injury can leave rips and tears in the delicate bundles of nerve cells (neurons) of the central nervous system. Often this trauma is so great that the glial cells that nurture our neurons’ natural growth are unable to bridge the gaps. Pictured in green with their nuclei stained blue, these glial cells have been grown outside of the human body. The cells on the right were given manmade nanofibres as scaffolding and, like a garden vine climbing along a fence (only 10,000 times smaller), have stretched out as they might along the spine. Such growth guidance could be an important first step to healing complex spinal injuries. In the future, meshes of different types of glial cells designed and grown outside the patient, could be transplanted to encourage neurons to knit back into damaged areas.

What is BPoD?

BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
