Question

Quizplus · Accepted Answer

Schwann cells play a crucial role in nerve regeneration in the peripheral nervous system (PNS). They release growth factors and create a favorable environment for the regrowth of injured nerve fibers, which makes them a promising candidate for the treatment of spinal cord injuries. While Schwann cells do form a myelin sheath around nerve fibers, this is not what makes them unique in terms of their potential therapeutic value. The other options listed (C and D) are not accurate statements about Schwann cells.
