Protective effects of acetyl-L-carnitine against serum and glucose deprivation-induced apoptosis in rat adipose-derived mesenchymal stem cells.

Low survival rate of grafted mesenchymal stem cells (MSC) in injured tissue is one of the major limitations of stem cell therapy. One of the most important factors that limits the MSCs survival rate and retention is ischemic stress, which can lead to damage to all components of the cell. In particular, it can damage mitochondria, that play an important role in apoptosis with releasing apoptotic factors.

Synergistic Effects of Acetyl-l-Carnitine and Adipose-Derived Stromal Cells on Improving Regenerative Capacity of Acellular Nerve Allograft in Sciatic Nerve Defect.

The combination of decellularized nerve allograft and adipose-derived stromal cells (ASCs) represents a good alternative to nerve autograft for bridging peripheral nerve defects by providing physical guidance and biologic cues. However, the regeneration outcome of acellular nerve allograft (ANA) is often inferior to autograft. Therefore, we hypothesized that acetyl-l-carnitine (ALCAR) treatment and implantation of ASC-embedded ANA would work synergistically to promote nerve regeneration.

The Effect of Memantine on Functional Recovery of the Sciatic Nerve Crush Injury in Rats.

Aim: Following severe peripheral nerve injury (PNI), regeneration is often insufficient and functional recovery is incomplete. In this regard, glutamate N-methyl-D-aspartate (NMDA) receptor antagonist such as Memantine have been shown to have neuroprotective effects. We evaluated the effects of Memantine against sciatic nerve crush injury in male Wistar Rats.
