The University of Minnesota is proceeding with embryonic stem cell research, despite an anti-abortion group’s claim that it is illegal under a new ban on the use of state tax dollars for human cloning.
Minnesota Citizens Concerned for Life called on the university Tuesday to “cease its pursuit of human cloning and to end its violation of state law through its ongoing destruction of human embryos.” The organization cited the new cloning ban, along with legislative testimony from a U executive that the ban would stifle “ongoing” research if passed.
University spokeswoman Mary Koppel said the executive’s comments referred
University of Minnesota Medical School researchers have developed a new strategy to improve the development of induced pluripotent stem cells (iPS).
Currently, iPS cells are created by introducing four defined genes to an adult cell. The genes reprogram the adult cell into a stem cell, which can differentiate into many different types of the cells in the body. Typically, the four genes introduced are Oct4, Sox2, Klf4 and c-Myc, a combination known as OSKM.
The U of M researchers found that by fusing two proteins – a master stem cell regulator (Oct4) and a fragment of a muscle cell inducer (MyoD)
A 3-year-old South Dakota boy whose brain tumor treatment had been in question because of an insurance dispute is set to begin chemotherapy in Minnesota this week.
Cooper Urbaniak, who suffers from ependymoma, is to be admitted to the University of Minnesota Medical Center Tuesday to begin high-dose chemotherapy and a stem cell transplant.
The family’s insurance provider initially declared the procedure experimental and refused to pay for it. But under an agreement reached last month between Sanford Health Plan and the university, Sanford will pay for the chemotherapy and pay a discounted rate on the stem cell transplant.

In a medical first, University researchers have created a beating heart in the laboratory. Using detergents, they stripped away the cells from rat hearts until only the nonliving matrix, or “skeleton,” was left; they then repopulated the matrix with fresh heart cells.
If perfected, the technique may be used someday to generate new hearts for patients. In the United States alone, about 5 million people live with heart failure, 550,000 new cases are

Don’t look for this just yet at your neighborhood clinic, but Minnesota scientists are pushing stem cell therapies into new frontiers — into territory that is so open that doctors and regulators still are shaping practices and policies as they go along.
In one breakthrough, researchers at Mayo Clinic in Rochester obtained stem cells derived from the bone marrow of heart disease patients and guided the cells to help heal, repair and regenerate damaged heart tissue. This is “landmark work,” said an editorial accompanying their research report in Monday’s Journal of the American College of Cardiology.
And last week,
