While the ideas behind our topic are very strong, when actually sought out to achieve them, they are less likely to be the of the same simplicity. As odd as it sounds, some of the biggest limitations in stem cells aren’t in the stem cells themselves, instead they are in the component that needs to be fixed by the cells. For example, in the treatment of neurodegenerative diseases, stem cells need to be specialized in a way in which they understand what to fix. The problem though, is that we don’t know what type of neurons degenerate and what is lacking in them for them to degenerate this quickly. It is very unlikely that stem cells will be able to do much of anything if they don’t know what to repair. What we do know is that neurogenesis and neuroplasticity are impaired in brains of patients suffering from neurodegenerative diseases result in diminished growth factors. Research in neurodegenerative diseases focuses on understanding why neurons degenerate in brains with Alzheimer’s disease and how to either slow down the process or replace lost neurons. Since fewer neurons are being grown and the same rate of neurons diminishing as before, which then unknowingly leads to a rapid decrease in motor neurons. The breakthrough needed in order for stem cells therapy to become a major technology in nerve regeneration and to cure neurodegenerative diseases would be to research and discover the unique neural pathologies that affect each disease and find the reason behind neural loss, and the specific neural cells that are present in these pathologies.As for peripheral nerve injuries, direct nerve repair with surgical interventions is still the treatment of choice. Current experimental research in peripheral nerve regeneration aims to accelerate the process of regeneration using pharmacologic agents and the bioengineering of nerve tubes. By targeting areas of choice in molecular pathways, these pharmacologic mediums allow for a better recovery in the nerve when it comes to functionality.
