Spinal cord injuries (SCIs) are often caused by accidents and can lead to significant disability, especially in young people. Current treatments aim to prevent further nerve damage, reduce inflammation and scarring, and encourage nerve regeneration. Hydrogels are materials with good compatibility with the body, adjustable properties, and the ability to act as carriers for cells and drugs. They can provide structural support and promote cell growth and tissue repair in the injured spinal cord. This review discusses how hydrogels can be used, alone or with cells and molecules, to repair SCIs. It also explores the potential of hydrogels in clinical research, offering new ideas for SCI treatment.
Hydrogels can be used as drug delivery systems to provide sustained local drug release in SCI, improving the therapeutic effect of drugs and reducing drug toxicity.
Hydrogels can be combined with cell therapies, such as neural stem cell transplantation, to promote cell survival, differentiation, and integration into the injured spinal cord.
Hydrogels can be modified to create a more favorable microenvironment for nerve regeneration, including reducing inflammation, inhibiting glial scarring, and promoting axon growth.
