Nerve tissue engineering is an application of tissue engineering in peripheral nerve regeneration, and tissue-engineered nerve grafts, like other tissue-engineered constructs, are typically composed of a nerve scaffold combined with cellular and/or molecular components. A team of researchers from RMIT University in Australia, working with scientists from India and Bangladesh have developed a neuron-growing ink that uses the body’s own electrical signals to precisely guide the growth of nerve cells. Their work opens a new avenue in nerve engineering.
