Laser Phototherapy: A New Modality for Nerve Cell Tissue Engineering Technology, Cell Therapy and Nerve Repair
نویسنده
چکیده
Studies, which evaluated the effects of 632.8nm and 780nm laser irradiation on Schwann 1 and nerve cell 2 cultures and injured peripheral nerves of animals 3-7 showed positive results. Laser phototherapy induces Schwann cell proliferation 1 and affects nerve cell metabolism and induces nerve processes sprouting 2. Laser phototherapy significantly improves recovery of the injured peripheral nerve 3,4,6,7 and, in addition, decreases posttraumatic retrograde degenera-tion of the neurons in the corresponding segments of the spinal cord. 5 Our previous studies investigating the effects of low power laser irradiation 632.8 and 780nm on injured peripheral nerves of rats have found: 1. Protective immediate effects which increase the functional activity of the injured peripheral nerve. 8 2. Maintenance of functional activity of the injured nerve over time.

The cellular therapy and nerve tissue engineering will probably become a major therapeutic strategy for promoting axonal growth through injured area in central nervous system and peripheral nervous system in the coming years. The stem cell carrier scaffolds in nerve tissue engineering resulted in strong survival of cells and suitable differentiation into n...
متن کاملMorphological Identification of Cell Death in Dorsal Root Ganglion Neurons Following Peripheral Nerve injury and repair in adult rat
Background: Axotomy causes sensory neuronal loss. Reconnection of proximal and distal nerve ends by surgical repair improves neuronal survival. It is important to know the morphology of primary sensory neurons after the surgical repair of their peripheral processes. Methods: Animals (male Wistar rats) were exposed to models of sciatic nerve transection, direct epineurial suture repair of sciati...

Posttraumatic nerve repair and prevention of muscle atrophy represent a major challenge of restorative medicine. Considerable interest exists in the potential therapeutic value of laser phototherapy for restoring or temporarily preventing denervated muscle atrophy as well as enhancing regeneration of severely injured peripheral nerves. Low-power laser irradiation (laser phototherapy) was applie...

Objective(s): To investigate the systemic and local immune status of two surgical rat models of sciatic nerve injury, a crushed sciatic nerve, and a sciatic nerve transection Materials and Methods:Twenty-four adult male Sprague-Dawley rats were randomly divided into three groups: sham-operation (control group), sciatic nerve crush, and sciatic nerve transaction. Sciatic nerve surgery was perfor...
