Hyped Embryonic Stem Cell treatments:
Mixed results in animal models.More successful, ethical alternative:
Treating HUMANS today.
Parkinson's Disease
In 2004, human embryonic stem cells were differentiated into
dopamine-producing neurons and transplanted into a rat model of Parkinson's.
This treatment only "slightly" improved symptoms in rats (about 25%).
In a similar study in 2002, one-fifth (20%) of the rats died of brain tumors
caused by the embryonic stem cells. Hardly a successful treatment when 20%
of subjects are killed in the process.
Parkinson's patient treated with his own adult stem cells continues to
exhibit relief from 80% of his symptoms more than 6 years after his surgery.
A Phase I human clinical trial using this therapy is currently underway.
Dennis Turner????????
A Phase II clinical trial is underway in human patients using a growth
factor to stop the destruction of neurons in the brain. In the Phase I
trial, patients showed 60% improvement in their symptoms. What is
this???????
