Thanks for the linka.

Yes it's 2 separate studies. The first used adult cells for the genetically caused myelin deficiency. At first I was saddened to see the use of immunosuppressants until I recalled the genetic deficiency.

The second used IPSC according to ScienceNOW, but Nature News implies embryonic stem cells.

But over the past four years, Sasai has used mouse embryonic stem cells to grow well-organized, three-dimensional cerebral-cortex1, pituitary-gland2 and optic-cup3 tissue. His latest result marks the first time that anyone has managed a similar feat using human cells.
