An article recent researchers medical Israel describes For a boy developed tumors brain and spine four years receiving cells fœtales therapy for genetic rare.
The case was reported by Ninette Amariglio and Gideon Rechavi of the Sheba Medical Center, Tel Aviv, and his colleagues in the February 17 issue of open access general medical journal PLoS Medicine.
Most body cells very différenciés eg brain and spinal have two types cells neurons transmitting electrical and glia support and protect. If these highly specialized cells are damaged or diseased, they can not be replaced.
Scientists believe cells neurales (undifferentiated master, cells who potential become one cell types brain) may answer to manufacturing new neurons replacing those damaged by stroke, trauma and degenerative diseases like Parkinson’s disease.
Critics therapy cells strains and therapy cells embryonic particularly say not only morally debatable but due risk cancer (cells reassortment multiplying Similarly that cells tumorales) and because virus used therapies unpredictable may develop in body recipient.
In this cases boy, now aged 17 was treated cells strains fœtales therapy 2001 another clinical Moscow and four years images showed he excrescences abnormal on his brain and cord spial.
Tumors benign are effect rare therapy cells fetal says author which suggèrent not research therapies using cells embryonic must cease but than biology underlying particularly their safety must be further investigated.
