Spinal cord injury (SCI) leaves severe sequelae, but a groundbreaking treatment has now been proposed: therapy using tiny capsules called exosomes (DPSC-Exos) secreted by dental stem cells (DPSC).
This study elucidated the mechanism by which DPSC-Exos promote axonal repair after SCI. DPSC-Exos strongly suppress the “neuroinflammation” that occurs excessively at the injury site, as well as abnormal cell death (apoptosis). This protects neurons, improves their survival environment, and, as a result, was shown to promote the regeneration of damaged axons.
This discovery opens a new path of “cell-free therapy” for SCI. Compared with transplanting the cells themselves, DPSC-Exos are less invasive and offer higher safety, and they are expected to become a promising therapeutic agent that achieves neuroprotection and regeneration simultaneously.
