In the medical field, experiments are done to test for the uses of cell-cell fusogens in axonal nerve repairs and to determine their usefulness with other nerve cells. The current method for nerve repair is suturing the cut ends of nerves. This has a long recovery process, with a low functionality rate for the repaired nerves. When considering cell-cell fusogens as a potential answer, researchers divided these fusogens into two groups based on fusion mechanisms: cell aggregation and membrane modification. One fusogen PEG was found to fit in both groups. It was this fusogen that made restoring nerve cells in humans possible. Once operations were within a certain time frame (12 hours for human nerve repair and 24 hours for sciatic rat treatments), patient recovery was almost successful. With this research, there is potential for repairing human nerve grafts. Some potential uses of cell-cell fusogens studied are cancer vaccines and the regeneration of damaged cells. Additionally, any peripheral nerve in the body could be repaired, and transferred tissues could work as soon as the senses return. Finally, any surgery done on nerves could be repaired as well, thus resulting in a quicker recovery.
