One of the characteristics they have in common neurodegenerative diseases Like Alzheimer’sIs the existence of neuronal death , the neurons difficult to regenerate themselves , we need to regenerates Stem Cells from any possible sources such as embryos, umbilical cord or bone marrow , which must be injected directly into the brain, this procedure is obviously impractical and invasive.
Another method is to inject blood Growth factors, That stimulate the brain’s own stem cells to regenerate neurons , however , this method has a small problem, since these factors to be dumped in the blood, may interact with some other type of tissue other than the brain .
to solve this problem , researchers are developing Spanish Nanoparticles, who act as a vehicle nanotechnology, and allow well , carry the growth factors specifically to the brain, and not to other tissue, by means of molecular markers that would only affinity receptors located on the surface of neurons, and only in that instead deposited the factors.
This is an application most of Nanotechnology in Biomedicine and future are expected to be present in all areas of medicine.
