L a charge will be company Geron Corp, those stem cells tested in eight or ten people paralyzed from the chest down who have suffered the injury between about seven and fourteen days ago.
E n principle, the tests are intended to discover whether the application of embryonic stem cells (or stem cells) is safe for the patient. In addition, we verify whether there is any kind of improvement and if they regenerate damaged nerves, making the sensitivity and even patients recover movement. E
ste method was approved by the Food and Drug Administration (FDA ) of EE. UU. With this approval marks a turning point between the new administration of Barack Obama who hinted before taking presidency that made more flexible restrictions on stem cell research.
L the FDA approved the test after reviewing 22,000 pages a year in which the company says it has been working with animals to demonstrate that embryonic stem cells cause tumors in tests on animals so far.
L to state funding of stem cell experiments in the United States was banned until August 2001, when Bush authorized it but only with cell lines already in existence.
STEM CELLS, STEM CELLS or STEM CELLS: a cell that has the ability to self-renew through mitotic divisions or continue the differentiation pathway for which is scheduled and one or more roduce mature tissues, functional and fully differentiated according to their degree of multipotency.
Most tissues of an adult have a very specific population of stem cells that allow the replacement or regeneration when tissue damage occurs. Some adult stem cells are capable of differentiating into more than one cell type while others are believed to direct precursor cells in the tissue in which they find themselves.

Embryonic stem cells are those that form part of the inner cell mass of an embryo 4-5 days of age and have the ability to form all cell types of an adult organism. A key characteristic of embryonic stem cells is that they can remain indefinitely. Since the split always form a cell identical to themselves, always maintaining a stable population of stem cells.
