Blood–spinal cord barrier

Semipermeable anatomical interface

The blood–spinal cord barrier (BSCB) is a semipermeable anatomical interface that consists of the specialized small blood vessels that surround the spinal cord. While similar to the blood–brain barrier in function and morphology, it is physiologically independent and has several distinct characteristics. The BSCB is involved in many disorders affecting the central nervous system, including neurodegenerative diseases, pain disorders, and traumatic spinal cord injury. In conjunction with the blood–brain barrier, the BSCB contributes to the difficulty in delivering drugs to the central nervous system, which makes drug targeting of the BSCB an important goal in pharmaceutical research.
