Description

technical field [0001] The invention relates to the technical fields of regenerative medicine and biomaterials, in particular to a preparation method of a material for spinal cord injury repair and bone and spinal cord tissue engineering scaffold. Background technique [0002] Currently, more than 27 million people worldwide are disabled due to spinal cord injury. Spinal cord injuries can have a variety of causes, including trauma, inflammation, infection, vascular causes, tumors, or degeneration. 90% of them are caused by trauma. For example, factors such as spinal trauma often lead to vertebral fractures, which compress the spinal cord parenchyma and cause spinal cord injury and the death of spinal cord neurons. After the death of spinal cord neurons, the interrupted nerve bundles cannot transmit information, resulting in multi-system dysfunction and sensory, motor, and autonomic dysfunction. Neurological dysfunction. Spinal cord injuries often result in permanent defic...
