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

Everyone knows about the potential of stem cells in the medical field, but until today, no one had found a way to recognize them in an organ or tissue. Thanks to a new study published in the ‘Proceedings of the National Academy of Sciences’ by 2007 Nobel Prize winner for Medicine, Mario Capecchi and researcher at Cattolica University in Rome, Eugenio Sangiorgi, this obstacle has been overcome. Experts have found a new technique to find stem cells hidden in the pancreas.
“Although the journals talk a lot about this topic,” said Sangiorgi, who has collaborated with
Stem cells are not invincible and therefore not likely to be the magic wand in the world of medicine, but they may be a great clue in finding what will be, a research professor explained on Thursday.
As part of a stem cell seminar series, Barbara Driscoll, Ph. D presented a lecture in the U Building titled “The Impact of Aging on Stem Cells.” The presentation covered basic information about stem cells, the aging process of mammals and how the two are so crucial to the next great discovery in medicine.
Driscoll is an assistant professor of Developmental Biology at USC
Cells from people with premature aging disease get “younger” with the help of stem cell technology.
Premature aging is one of the most difficult-to-deal with conditions in the world. In addition to its physical consequences, its psychological impact is devastating on a person suffering from it. At this point, experts believe that the disease is caused by the fact that people predisposed to it have very short telomeres, which are repetitive stretches of DNA attached to the end of each chromosome in each cell featuring genetic material in the human body. As chromosomes multiply, the telomeres naturally get shorter, and
The same genes that are chemically altered during normal cell differentiation, as well as when normal cells become cancer cells, are also changed in stem cells that scientists derive from adult cells, according to new research from Johns Hopkins and Harvard.
Although genetically identical to the mature body cells from which they are derived, induced pluripotent stem cells (iPSCs) are notably special in their ability to self-renew and differentiate into all kinds of cells. And now scientists have detected a remarkable if subtle molecular disparity between the two: They have distinct “epigenetic” signatures; that is, they differ in what gets
