Primele teste terapeutice cu celule STEM prelevate din embrioni umani a fost aprobata

Administratia FDA americana (Us Food and drug) a aprobat primele teste cu celule STEM prelevate din embrioni umani pentru o terapie pionierat in domeniul tratarii persoanelor paralizate, ce va schimba politica celulelor STEM sub administratia prezidentiala Barack Obama.
"AFP- US authorities have approved the first human trials using embryonic stem cells to test a pioneering therapy for paralyzed patients, the FDA said Friday. "The FDA has granted its clearance for a new drug application of Geron Corp for a phase one clinical trial of an embryionic stem-cell based therapy in patients with acute spinal cord injury," FDA spokeswoman Susan Cruzan told AFP. Earlier, the US biotech firm Geron Corp. announced it had been cleared to carry out the human trials, testing the therapy on patients paralyzed by spinal-cord injury. In a press release, the Menlo Park, California firm said the US Food and Drug Administration (FDA) had cleared it for the first phase of trials of a novel therapy called GRNOPC1. Embryonic stem cells are highly versatile, primitive cells capable of developing into any tissue of the body. The goal is to inject cells into the spines of paralyzed volunteers in the hope that this will prompt damaged nerve cells to regrow, enabling the patients to eventually recover feeling and movement. "The clearance enables Geron to move forward with the world's first study of a human embryonic stem cell based therapy in man," Geron said. All federally-funded research on new lines of embryonic stem cells was banned under the previous administration of president George W. Bush. President Barack Obama said before Tuesday's inauguration that he hopes Congress will introduce legislation to overturn the ban."

SUA incepe studiile cu celule STEM pe subiecti umani

Compania A U.S. biotech declara ca planuieste in aceasta vara sa demareze primul studiu mondial efectuat pe subiecti umani, tratament bazat pe celule Stem. Compania a primit accept federal in aceasta saptamana pentru a injecta 10 pacienti cu celule derivate din celule embrionale spune Dr. Thomas Okarma presedinte al Geron Corp Menlo Park, Calif. Acesti pacienti sunt paraplegici care isi pot misca mainile dar nu isi pot folosi picioarele, ei vor primi o singura injectie in doua saptamani de la petrecerea leziunii. Studiul are ca tinta testarea sigurantei procedurii dar totodata doctorii vor cauta semne de imbunatatire ca exemplu revenirea senzatiei in picioare sau miscare la nivelul membrelor spune Dr. Okarma. Indiferent de rezultate studiul va marca un nou capitol in discutata istorie a cercetarii celulelor STEM in SUA. Sursa
