The scientists injected the gel in the manner of cumin with paralyzed mice – walking




The scientists injected the regeneration gel into the injured area with paralyzed mice, so they started walking again after four weeks.

It is a gel that gives signals that stimulate nerve regeneration and mimic the structure around cells, creating a kind of scaffold that helps cells grow.

Chemist Samuel Stup of Northwestern University in Chicago and his colleagues made this gel from protective units, monomers, that come together in long chains called supramolecular fibrils.

When the cited fibrils are injected into the cumin mode of the paralyzed mice, they form a gel at the wound site.

The gel helped with regeneration

Scientists injected fibrillation or treatment last year into 76 paralyzed men the day after the injury. Mice that received the gel were shown to walk four weeks after receiving the gel, while those that received the placebo remained largely paralyzed.

That is, ice has helped to strengthen the ends of neurons and reduce the level of damaged tissue at the site of injury, which is usually an obstacle to regeneration. The gel also stimulated the growth of veins, which in turn brought more nutrients to the cumin cells.

Two ways to evaluate recovery

Experts evaluated my recovery in two ways. First give him an overall score regarding his movement, body stability, ap position and steps. Mievi who received the gel had a quality three times better than those who received a placebo.

Next, they assessed their ability to walk by dipping their hind legs into paint and letting them walk on a narrow strip of white paper. This test showed that mice given the gel had better width and stride length.

“Longer stride lengths and widths should correlate with more cultured nerve fibers,” Stup said.
