Stem Cells Made From Cloning Diabetic Woman

By NEVAGiles23

Scientists have used cloning technology to make stem cells from a woman with Type 1 diabetes that are genetically matched to her and to her disease.

They hope to someday use such cells as tailor-made transplants to treat or potentially even cure the disease, which affects millions and which now has few treatment options other than careful diet and regular use of insulin.

Its the second report his month of success in using cloning technology to make human embryonic stem cells the cells that eventually create a complete human being and that scientists hope to harness to treat diseases ranging from diabetes to Parkinsons and injuries that cause paralysis or organ damage.

I think this is going to become reality, Dr. Dieter Egli of the New York Stem Cell Foundation, whose report is published in the journal Nature on Monday, told reporters. It may be a bit in the future but it is going to happen.

The technique they use is called somatic cell nuclear transfer the same method used to make Dolly, the sheep who was the first mammal to be cloned, in 1996. Scientists remove the nucleus from a normal cell, clear the nucleus from a human egg cell, then inject the nucleus from the skin cell into the egg.

I think this is going to become reality."

Various chemical or electrical tricks can be used to start the egg growing as if it had been fertilized by sperm. In this case, they used DNA from a woman with Type 1 diabetes, and they said they used an improved method to trick the egg into developing.

It got to whats called a blastocyst a ball of cells that has not yet begun to differentiate into the different types of cells and tissues in the body, such as nerve cells, blood cells and bone cells. They removed individual cells and used various chemical baths to direct them to form into the desired cell type the beta cells in the pancreas that make insulin and that are destroyed in diabetes. These cells carry the patients own unique DNA, including whatever genetic mistakes led to her diabetes.

These stem cells could therefore be used to generate cells for therapeutic cell replacement, they wrote in their report.

Scientists have cloned sheep, pigs, mice and monkeys, but its been far harder to clone human beings. Its partly because of the controversy few people advocate cloning humans for the purpose of making babies, and many people object to destroying a human embryo, even one that only ever existed in a lab dish.
