GERMANY – Stem Cells, One Factor Can Almost Transform Adult Stem Cells into Embryonic Stem Cells

One factor, not four like a majority of biologists throughout the world have said up until now, is sufficient to convert an adult stem cell into a cell that is similar to an embryonic stem cell. A recipe that is much more simple than what the scientific community has believed has been discovered by Hans Schöler and his colleagues, who include Italians ,Vittorio Sebastiano and Luca Gentile, from the Max Planck Institute for Molecular Biomedicine in Germany. The study, published in February’s edition of Cell, shows for the first time that nerve stem cells taken from

MyoD Helps Stem Cells Proliferate in Response to Muscle Injury

The master regulator of muscle differentiation, MyoD, functions early in myogenesis to help stem cells proliferate in response to muscle injury, according to researchers at Case Western Reserve University.
The study appears online Jan. 4 in the Journal of Cell Biology.

Massachusetts Scientists Make Stem Cell Discovery

Stem cell researcher Dr. Ann Kiessling announced today the discovery of cell characteristics that may explain important differences between embryonic stem cells and adult stem cells. Scientists have for years been frustrated in their efforts to grow the trillions of adult stem cells needed for therapies, which is why embryonic stem cells seem promising — they can multiply endlessly and also develop into any cell in the body.

Kiessling discovered that early human embryo cells express CLOCK, and other circadian genes, that other human cells growing in laboratories did not. This was a surprise. Although scientists have recently

SPAIN – In the stem cell factory

Culturing stem cells to use to treat certain illnesses is already a reality. In Spain, two labs have received authorization from the Agencia Espanola de Medicamento y Productos Sanitarios to produce stem cells, and there are others waiting to be certified.

Currently, just one public health center, the Gregorio Maranon Hospital in Madrid (HGM) and one private center, the Clinica Universitaria in Navarra (CUN) have undergone the rigid system of quality certification to become “Good Manufacturing Regulations” (GMR) laboratories and are developing stem cell products to be administered and transplanted into

ITALY – Ready for stem cells gathering

At the San Timoteo Hospital in Termoli-Larino (Molise, a small region in south central Italy, formerly part of the region “Abruzzi e Molise”) everything is ready for stem cells gathering – in conjunction with the orthopedy ward (branch of medicine dealing with diseases of the bones and joints) – which will be used for local treatments, above all on pseudo-arthrosis.
