Stem cells hold promise for male sterility

A Montana State University researcher and her co-researchers are receiving international attention for showing that skin cells from infertile men can be used to create the precursors of sperm – research that holds promise for treating male infertility (…)

The team took skin cells from men who suffer from a genetic disorder, known as azoospermia, which prevents them from producing sperm. Those skin cells were then turned into stem cells, specifically, induced pluripotent stem cells, or iPSC. Like other stem cells, iPSC have the ability to become any other type of cell.

The team then implanted the stem cells into the

EUROPE – Misleading advertisements about vegetable stem cells halted

Misleading advertisements by Swedish company Labo promising hair growth and to remove wrinkles have been pulled. The jury of the self-regulating body for the advertising industry (IAP) ordered the advertisements, which were found in two important Italian newspapers, to be stopped since they were “in violation of article 2 of the self-regulatory code for advertisements”.

According to the group’s conclusions (ruling number 13/09), the statements made in the message, as noted by the IAP Surveillance Committee, “did not overstate, they were misleading”.

This is due to the fact that “they were characterized by a technical and scientific language

UTHealth research shows modified adult stem cells may be helpful in spinal cord injury

Researchers at UTHealth have demonstrated in rats that transplanting genetically modified adult stem cells into an injured spinal cord can help restore the electrical pathways associated with movement. The results are published in today’s issue of the Journal of Neuroscience.

In spinal cord injury, demyelination, or the destruction of the myelin sheath in the central nervous system, occurs. The myelin sheath, produced by cells called oligodendrocytes, wraps around the axons of nerves and helps speed activity and insulate electrical conduction. Without it, the nerves cannot send messages to make muscles move.

The research team, led by Qilin Cao, M.D., principal investigator

Now, a new tool to examine cancer growth

Image via Wikipedia

Scientists have developed a new tool that illuminates connections between stem cells and cancer.
Researchers have been successful in breaking apart human prostate tissue, extract the stem cells in the tissue, and alter those cells genetically so that they spur cancer.

Many tissues contain pools of stem cells that replenish the tissue when it’s damaged or when changes take place. For example, stem cells in the skin produce new cells to replace those irreparably damaged by the sun, and stem cells in the breast create milk-producing cells when a woman is pregnant.

A characteristic of these stem cells is that

SWITZERLAND – Investments in Stem Cell Research

Image via Wikipedia

Halfway through February, the National Swiss Fund has established a national plan for stem cell research and regenerative medicine, providing 10 million francs (6,766,000 euros) in financing over 5 years. In November, the Foundation will make a decision on projects that have already been submitted. In January 2010, those which have been approved will get underway. The objective is to favor basic biological stem cell and regenerative medicine research, and to spread awareness internationally.

At the end of 2004 in a referendum, Swiss citizens approved a law that allows the use of excess embryonic
