Bone Marrow-Derived, Neural-Like Cells Have the Characteristics of Neurons to Protect the Peripheral Nerve in Microenvironment

الملخص EN

Effective repair of peripheral nerve defects is difficult because of the slow growth of new axonal growth.

We propose that “neural-like cells” may be useful for the protection of peripheral nerve destructions.

Such cells should prolong the time for the disintegration of spinal nerves, reduce lesions, and improve recovery.

But the mechanism of neural-like cells in the peripheral nerve is still unclear.

In this study, bone marrow-derived neural-like cells were used as seed cells.

The cells were injected into the distal end of severed rabbit peripheral nerves that were no longer integrated with the central nervous system.

Electromyography (EMG), immunohistochemistry, and transmission electron microscopy (TEM) were employed to analyze the development of the cells in the peripheral nerve environment.

The CMAP amplitude appeared during the 5th week following surgery, at which time morphological characteristics of myelinated nerve fiber formation were observed.

Bone marrow-derived neural-like cells could protect the disintegration and destruction of the injured peripheral nerve.
