Almost total relief of symptoms tempered by hints of cancerous side effects.

In a recent research on stem cell treatment, Goldman and his colleagues found that stem cell treatment has relieved symptoms of Parkinson’s disease.
Parkinson’s disease kills off the neurons that produce dopamine, thus causing problem with movement and balance
Goldman and his team used human midbrain tissue in which dopamine cells are made and took the glial cells (function: for maintaining proper growth of neurons) .The stem cells where cultured in the glial rich environment.
The new dopamine neurons where transplanted into the rats brains. The results showed that the animal recovered and showed proper movements.
But the problem that lies with such treatment is that their also remain certain cell which fail to become neuron and are undifferentiated, thus keep on dividing and can cause tumour.
