Stem cell-based brain repair is a promising emergent therapy for Parkinson's disease based on years of foundational research using human fetal donors as a cell *** current therapeutic options for patients,this approach has the potential to provide longterm stem cell–derived reconstruction and restoration of the dopaminergic input to denervated regions of the brain allowing for restoration of certain functions to *** ultimate clinical success of stem cell–derived brain repair will depend on both the safety and efficacy of the approach and the latter is dependent on the ability of the transplanted cells to survive and differentiate into functional dopaminergic neurons in the Parkinsonian *** the pre-clinical literature suggests that there is considerable variability in survival and differentiation between studies,the aim of this systematic review was to assess these parameters in human stem cell-derived dopaminergic progenitor transplant studies in animal models of Parkinson's disease.A defined systematic search of the PubMed database was completed to identify relevant studies published up to March *** screening,76 articles were included in the analysis from which 178 separate transplant studies were *** these,graft survival could be assessed in 52 studies and differentiation in 129 ***,we found that graft survival ranged from<1% to 500% of cells transplanted,with a median of 51%of transplanted cells surviving in the brain;while dopaminergic differentiation of the cells ranged from 0% to 46% of cells transplanted with a median of 3%.This systematic review suggests that there is considerable scope for improvement in the differentiation of stem cell-derived dopaminergic progenitors to maximize the therapeutic potential of this approach for patients.

Alzheimer’s disease(AD)is one of the major forms of dementia,accounting for 60 to 80%of the cases of dementia,affecting approximately 50 million people worldwide,which is why it has become an object of great interest in both the medical and social fields(Source:Alzheimer’s Association).One of the main histopathological hallmarks of AD is the formation and accumulation of senile plaques in the brain parenchyma,mainly composed by fibrillar aggregates of the amyloidβ(Aβ)*** peptide is generated by the cleavage of the membrane protein named amyloidβprecursor protein,and its secretion in the extracellular space leads to its aggregation into amyloid *** intermediates of this process of aggregation have been identified,and it was found that prefibrillar,soluble oligomeric forms of Aβare more likely to be the pathological species(Benilova et al.,2012).
