Stem Cells Against False Joints

Image via Wikipedia

Russian scientists started clinical trials of treating false joints by means of demineralized bone matrix with introduced mesenchymal stem cells of a patient.

False joints often occur as a complication during fractures of long bones, when splinters do not adhere, and cartilage layer forms between them. This layer is called false joint, and in this case, additional surgery is required to help a bone to heal.

Modern surgeons fight this problem with bone transplants, but bone recovery takes about one year. Possible solution is transplantation of mesenchymal stem cells of bone marrow, which can turn into various cells, including

Skin cells transform to liver cells

In a fresh demonstration of science’s newfound ability to alter the basic units of human life, researchers at the Medical College of Wisconsin have turned the cells in human skin into those in the liver, work that opens new avenues for treating diseases of the liver without relying on organ transplants.

Professor and stem cell researcher Stephen A. Duncan and other scientists in his lab reported this week in the journal Hepatology that they have created reprogrammed mouse liver cells that were identical to those grown in nature and were able to integrate and grow alongside those in a mouse

ISCO open Its Brand of Human Cell Culture Products for Japanese Markets

International Stem Cell Corporation, announced today its wholly-owned subsidiary, Lifeline Cell Technology (Lifeline), has signed a distribution agreement with Tokyo-based Veritas Corporation to distribute its human cell culture products throughout Japan.

Lifeline, located in Maryland and California, specializes in the development, manufacture, and distribution of products to culture human cells for the study of human disease, including products to culture primary human cells and human stem cells. These products are being requested by customers overseas, including customers in Japan, Korea and India and this agreement is the first step in Lifeline’s plan to meet these requests.

ITALY – Minister Sacconi questioned about the destruction of umbilical cord stem cells in Matera

Statement by Maurizio Bolognetti, Secretary of the Associazione Radicali Lucani (Radical Association of the Lucania Area)

As recently stated, Senators Perduca and Poretti have questioned individuals about the stem cell bank in Matera. After three years, it is necessary to finally shed light on the matter, which has not been clearly explained. The many mothers who have donated umbilical cords have the right to know the truth about how and why an opportunity to potentially treat individuals was lost. EU Parliament member Marco Cappalto expressed his desire for Minister Sacconi to provide clear

Possible cancer-causing genes taked off from engineered stem cells

Image via Wikipedia

Whitehead Institute researchers have developed a novel method of removing potential cancer-causing genes during the reprogramming of skin cells from Parkinson’s disease patients into an embryonic-stem-cell-like state. Scientists were then able to use the resulting induced pluripotent stem (iPS) cells to derive dopamine-producing neurons, the cell type that degenerates in Parkinson’s disease patients.

The work marks the first time researchers have generated human iPS cells that have maintained their embryonic stem-cell-like properties after the removal of reprogramming genes. The findings are published in the March 6 edition of the journal Cell.

Removing the reprogramming genes is also important because
