      "These are some of the effects analysts say they see coming out of this week's announcements that two teams have genetically reprogrammed skin cells so that they take on the traits of embryonic stem cells." 11-07

  7. -11-27-07 Implications of Stem Cell Breakthrough (New York Times)
      "Biologists were electrified on Tuesday, when scientists in Japan and Wisconsin reported that they could turn human skin cells into cells that behave like embryonic stem cells, able to grow indefinitely and to potentially turn into any type of tissue in the body."

      "The discovery, if it holds up, would decisively solve the raw material problem. It should provide an unlimited supply of stem cells without the ethically controversial embryo destruction and the restrictions on federal financing that have impeded work on human embryonic cells."

      "There are two ways that stem cells can lead to treatments for diseases. Making replacement tissues for ailing organs is the direct way. But many scientists say the biggest impact of the new cells will be on the indirect way: using the cells to learn about diseases and then applying that knowledge to develop conventional drugs. 11-07

  1. -Direct Conversion of Stem Cells (CBS News)
      "The new direct-conversion approach avoids embryonic stem cells and the whole notion of returning to an early state. Why not just go directly from one specialized cell to another? (It's like flying direct rather than scheduling a stopover.)" The direct-conversion of stem cells has resulted in "scientists converting mouse skin cells into nerve cells and heart muscle cells. And just this month came success with human cells, turning skin cells into early stage blood cells." 11-10

      "It's not quite human cloning, but it's close. Researchers reported using a variation of somatic cell nuclear transfer (SCNT) — the same technique that created Dolly the sheep, the first mammal to be cloned, from a skin cell of a ewe — on human cells. SCNT involves replacing the genetic material of an egg cell with the DNA from a mature cell (a skin cell, for example). The egg is then stimulated to divide, and if it develops fully, produces a genetically identical clone of the animal from which the mature cell was taken." 12-11

      "The opinions expressed in this commentary are solely those of Leonard I. Zon." 09-10

  10. Embryonic Stem Cell Research in the U.S. in Question (New York Times)
      "Perhaps more than any other field of science, the study of embryonic stem cells has been subject to ethical objections and shaped by political opinion. But only a year after the Obama administration lifted some of the limits imposed by President George W. Bush, a lawsuit challenging the use of public money for the research and a conservative shift in Congress could leave the field more sharply restricted than it has been since its inception a decade ago." 10-10

  11. Federal Judge Halts Some Federal Embryonic Stem Cell Research (CNN News)
      "A U.S. district judge granted a preliminary injunction Monday to stop federal funding of embryonic stem cell research that he said destroys embryos, ruling it went against the will of Congress."

  14. Method Found to Mass-Produce Embryonic Stem Cells (
      "That's important because traditional laboratory methods used to grow these cells are costly and don't produce cells fast enough to respond to increasing demands for human embryonic stem cells, said Shang-Tian Yang, a professor of chemical and biomolecular engineering at Ohio State University."

      "Federal rules forbid the federal funding of research on human embryonic stem cell lines that aren't listed on the National Institutes of Health's Human Embryonic Stem Cell Registry. There are currently 22 embryonic stem cell lines on the registry, and the demand for these cells is steadily growing."

      " 'We have to find a way to mass-produce them because traditional cell culturing methods can't meet the projected high market demand for stem cells,' Yang said."

      "He and Anli Ouyang, a doctoral student in chemical engineering, grew mouse embryonic stem cells in a bioreactor. Cell growth increased 193-fold in 15 days. At the end of that period, cell density - the number of cells that had grown in the bioreactor - was anywhere from 10- to 100-fold higher than the number of stem cells produced by conventional laboratory methods. That's several hundreds of millions more stem cells." 3-05

  28. Stem Cell Therapy (
      "Stem cells are the primordial cells in the human body. The first stem cells occur inside a developing embryo (blastocyst). These embryonic stem cells are understood to be totipotent (capable of differentiating into every cell types in a living body). They divide and differentiate to ultimately construct the entire human body."

  36. Stem Cells, Disease, and Aging (New York Times)
      "Thomas Rando, a researcher at Stanford University, thinks stem-cell treatments may enhance healing in older patients who have difficulty recovering from surgery or a fracture. But he's also thinking about deeper issues involving the power of regenerative medicine. 'There are very basic questions I hope we can make headway on using stem cells — in terms of understanding cellular aging, how that's related to tissue aging and the aging of an organism,' he says. Which leads to the interesting possibility that with stem cells, we may no longer define age as how old we think we are but as how old our cells tell us we are." 03-11

  37. Three Win Nobel in Medicine for Gene Technology (New York Times)
      "Two Americans and a Briton won the 2007 Nobel Prize in medicine today for developing the immensely powerful 'knockout' technology that allows scientists to create animal models of human disease in mice."
