According to The Times of India, Japanese scientists were able to create "embryonic-like stem cells" simply by "bathing ordinary skin or blood cells in a weak acid solution for half an hour".
Two studies in Nature have shown that there is now a third way of producing pluripotent stem cells, other than creating embryos or inducing the changes by introducing new genes into a cell. The third way is by far the simplest of the three approaches, scientists said.
The scientists believe that the acidity of the solution created a "shock" that caused the blood cells of adult mice to revert to their original, embryonic-like state. From this pluripotent state, the newly created stem cells were cultured in specially prepared solutions of growth factors to develop into fully mature cells, including an entire foetus.
