Scientists Move Closer to Human Therapeutic Cloning 136

"Human therapeutic cloning has moved a step closer after U.S. researchers said they had successfully created embryonic stem cells from monkey embryos. Scientists told a stem cell research conference in Cairns this week that they had successfully created two batches of embryonic stem cells from cloned rhesus monkey embryos."

      In real life there are more issues (not withstanding the moral issues if the clone is allowed to develop a brain). For instance, we are not purely a product of our genes. Otherwise identical twins would look identical until the moment they both suffered a heart attack and died. If you need a solid organ, it needs to be grown in a viable host. It's likely impossible using current (or near-future) technology to create a viable host that does not have brain activity.

    So for years the scientists have been finding the chromosomes to transplant by:

      - Flooding the donor cell with a fluorescent dye that bonds to DNA, then

      - Shining ultraviolet light (i.e. ionizing radiation) on the cell, causing the dye to fluoresce (and also dump enough energy into the DNA molecule to break molecular bonds and produce free radicals in the nearby area).

  • The recent advance of creating stem cells from skin cells (using embryonic stem cells cultured in the lab from previously collected stem cells) suggests to me that there are a potentially large number of other methods to obtain/generate these cells that does not involve the destruction of viable human embryos.

    I have also found it interesting that embryonic stem cells, apparently, can be taken from umbilical cords and placental cells. Why is this ignored in research (or is it a case of a percentage of resear
