re:pair is a start-up company that vision to revolutionize the field of tissue-engineered platforms.

peripheral nerves platforms

We aim to solve the unresolved need of supplying artificial nerve grafts for peripheral nerve reconstruction, that suit for injuries with varied gaps, with functional results similar to autologous nerve transplantation.  

Peripheral nerves are the communication structures that connect the brain and spinal cord to the rest of our body. Thus, peripheral nerve damage can result in a lack of communication between the brain and various organs and muscles. Unfortunately, peripheral nerves are relatively vulnerable and around the world more than one million people suffer from peripheral nerve damage each year. It is highly likely that such damage will be life-changing. 

Today, the ‘gold standard’ treatment for long nerve defects involves the surgical transplantation of nerve autografts. This procedure presents various limitations, as it requires very high surgical skills along with the risks of donor site morbidity, a limited amount of donor tissue, and esthetic problems to the patient. To issue the mentioned limitations artificial nerve grafts (ANGs) can be used, but currently in the clinic they can't achieve the functional "gold standard" results, and usually suitable for the treatment of nerve defects up to 2cm, while most of the injuries involve larger gaps.

In re:pair, we are taking an innovative combinatorial approach to solve those problems. We develop an off-the-shelf 3D artificial hydrogel-based graft that mimics the natural topography of nerves. This method has been proven to help the spontaneously-regenerating axons rapidly take the right path needed for the repair of long-distance nerve defects. 















Together, we aim to harness our knowledge to help people with peripheral nerve injuries. We are collaborating with world top neurosurgeons and aided by experienced mentors to create global impact and make our vision come true.
