Stem Cell Type	Advantages	Disadvantages
Neural	Ability to differentiate into multiple cell types Low risk of tumorigenesis	Variable study results Difficult to obtain Not able to restore complete brain function on its own
Induced pluripotent	Relatively easy to obtain Ability to differentiate into multiple cell types Low risk of immune rejection Maintained in vitro for multiple generations Able to completely restore brain function Disease modelling Drug/toxicity profiling	Tumorigenicity Low efficiency
Adipose derived	Easily collected from adipose tissue Low risk of tumorigenesis Low risk of immune rejection Safe intravenous administration Neuroprotective and possible neurogenesis	Only animal models, no clinical trials Uncertain differentiation into either neuronal or mesenchymal Not able to restore complete brain function on its own
