Recent trends in peripheral nervous regeneration using 3D biomaterials

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Neuroscience

Background:

• Mesenchymal stem cells (MSCs) are multipotent progenitors crucial for adult tissue regeneration, including neural tissue.
• Repairing traumatic nerves remains a significant challenge in neurosurgery.
• The cellular microenvironment critically influences stem cell differentiation and fate.

Purpose of the Study:
