Abstract
Transplantation of adipose-derived mesenchymal stem cells (ASCs) induces tissue regeneration by accelerating the growth
of blood vessels and nerve. However, mechanisms by which they accelerate the growth of nerve fibers are only partially
understood. We used transplantation of ASCs with subcutaneous matrigel implants (well-known in vivo model of
angiogenesis) and model of mice limb reinnervation to check the influence of ASC on nerve growth. Here we show that
ASCs stimulate the regeneration of nerves in innervated mice’s limbs and induce axon growth in subcutaneous matrigel
implants. To investigate the mechanism of this action we analyzed different properties of these cells and showed that they
express numerous genes of neurotrophins and extracellular matrix proteins required for the nerve growth and myelination.
Induction of neural differentiation of ASCs enhances production of brain-derived neurotrophic factor (BDNF) as well as
ability of these cells to induce nerve fiber growth. BDNF neutralizing antibodies abrogated the
