It is being reported that cloning technologies have been used to create stem cells which are genetically identical to adult patients for the first time ever. Cloned embryos can be used as a foundation for stem cells which match up to a person and can produce any kind of cell that is needed for the individual.
Researchers printed out two reports this month and created human embryos for this very purpose. Usually an embryo is created when a sperm fertilizes an egg; however in this case, scientists altered the nucleus of an adult skin cell inside the egg and then the reconstructed egg went through the early stages of embryonic growth.
Stem cells have the possibility to grow into any kind of tissue inside the human body. From becoming organs to treating diseases such as diabetes, numerous future medical improvements are hoped to come from stem cells.
Scientists stated that they decided to use skin cells from two men, one age 35, and another who was age 75, to produce the cloned embryo stem cells. They wrote up a research report for the journal Stem Cell.
Another team of researchers ended up with similar results that they published in the journal Nature using a parallel approach. They took skin cells from a woman, age 32, who suffered from Type 1 diabetes to create stem cells that matched her own body.
Each report is following groundbreaking research that was printed up in 2013 in the journal Cell. In that study, scientists created cloned embryos and stem cells by using the skin cells from both a fetus and also a baby that was less than a year old.
However in doing this, it is not clear if there are enough human eggs in supply to ever do a large scale creation of stem cells in this type of way, worry experts, but there appears to be plenty for near term research purposes of stem cell cloning. There are around 10,000 eggs donating annually in the United States. Yet even with that amount, egg donation for research is usually low. The American Diabetes Association state that around one million Americans suffer from Type 1 diabetes and they are the main population for any stem cell treatment.
Cloning methods usually take around a couple weeks, and including compensation to the woman, it can cost approximately $14,000. Yet a cloning may help scientists understand how an egg reprograms cells. It may help aid in answering how an egg resets the entire identity of a cell which is considered to be an adult all the way back to its embryonic state.
Stem cell cloning research just may show researchers how to produce stem cells more proficiently and enhance them for uses in the medical field. These embryos made from skin cells and eggs would never be able to grown into babies. In order to do that would have taken additional medical technology, which was never part of the research study.
It was explained that in these experiments where the human embryos were created in these stem cells, it would have been both unethical and very dangerous to try and transfer them into a uterus.
