The researchers reported in the Journal Nature that they had success in treating Parkinson's mice models with matched cloned embryonic stem cells. The researchers were trying to prove that it is possible to make cloned embryonic stem cells to provide a tailor-made treatment.
The experiment demonstrated that a mouse's own cloned stem cells were far less disruptive to its body than cloned cells taken from other mice. Cells extracted and cloned from other mice caused inflammation.
Cloning researchers hope one day to be able to extract and grow embryonic stem cells from a patient’s own skin and use it for personal, tailor-made medical treatments.
The next step is to clone the cells without the use of a embryo that would remove ethical objections to the process.
The procedure is incredibly difficult and will require years to refine. Nonetheless, it demonstrates a path to personal therapeutic medicine.
