Skin cells ‘scream’ for help when injured
Epithelial cells in our skin send electric signals such as neurons to cry for help

Neurons talk to each other with electricity. If you hear these impulses, they can always be consistent, fast fire chatter to all nervous systems. The heart muscle cells do the same, issuing “ho-ho” signals that make the organ lump.
The skin and other epithelial cells, however, thought to be silent; They form the barrier tissues that protect the body from outside the world, and they are not believed to be this type of communication. So researchers have been amazed at discovering new, if injured, these cells released a slow electric pulse in a way similar to neuron firing.
“Epithelial cells make a sign different from a scream: ‘We have been injured, we need to get better,'” As an engineer at the University of Massachusetts Amherst and President on National Academy Practices of Science USA. The signal can call other cells to help rebuild damaged areas.

Epithelial cells form the outer skin and line of shores, bloodways – each other’s organ, without connecting newly found cells in the medicine school cells. If injured, these cells were injured, these cells were injured, learned to associate well by passing chemical signals to their neighbors. But Yu said there was a faster signal of the epithelial. When he had a laser coated with a laser to strike the cells, He has some electrical “noise from locations near the holes.
“This is an apparent, active signal” that is strongly resembled by a servicic self neuron spikes, Yu said. These explosions are faster than chemical messengers but more slowly than signals in neurons; They slow down in seconds instead of milliseconds and targeted at least a dozen epithelial cells. It is unclear how epithelial cells make signals, but researchers know that these cells can only be fired in the presence of calcium ions. The Neuron sign knows that it also depends on the ions, including calcium, sodium and potassium; Electrical fee provides signage in signage voltage.
New observations “appear to have longer communications” between epithelial cells to coordinate with healing, Foxman said. Understanding exactly how to respond to these damage cells can be revealed why the process is sometimes wrong. “If you get a cut, sometimes it will be perfectly healing,” he said, but in other times the process leaves an epithelium in the room. “That’s what I’m feeling,” Foxman added. “When can you find a new passage, you can study and can be used (it) to develop a new treatment.”
It’s not sure what role is when this signing of living organisms or what other cells do when they receive a signal, studying the end yord cells. “What is the passage of this electric activity?” She thinks. Does it influence neurons? Yu next plan to study if these two kinds of communicating cells. “I would like to know how high-style signals (in neurons) are translated” for epithelial cells that are targeted by signals that are humbled, and vice verta, he said. “It’s a study that comes from our curiosity.”
