“Internal compass points cells towards injury”

“CELLS can’t see or hear, but some of them have a sense we lack: they can detect the electric fields generated by a wound.”

“Electrical signals control wound healing through phosphatidylinositol-3-OH kinase-γ and PTEN”

“Wound healing is essential for maintaining the integrity of multicellular organisms.”

“Electric Healing”

“A little electricity may dramatically speed up the healing of skin wounds”

“Healing power of electricity raises hope of new treatments”

“Scientists have found how the body harnesses the power of electricity to heal cuts and grazes – an effect they manipulated to speed up wound healing dramatically.”

“Emil Heinrich Du Bois-Reymond”

“German founder of modern electrophysiology, known for his research on electrical activity in nerve and muscle fibres.”

“Electricity to heal wounds”

“Researchers in Aberdeen have made an exciting breakthrough in showing that electricity has a major impact on the healing of wounds.”

“Keratocyte Fragments and Cells Utilize Competing Pathways to Move in Opposite Directions in an Electric Field”

“Sensing of an electric field (EF) by cells—galvanotaxis—is important in wound healing, development, cell division, nerve growth, and angiogenesis”
