Stem cell success: One couple's effort to protect their son from...

A new human embryonic stem cell line containing the genetic mutation for adrenoleukodystrophy , and neurons grown from those cells, are now helping scientists study the condition -- thanks to an embryo donated by a couple seeking to avoid passing the disease to their son. Once enough cells in a line have been generated, they're stored in a deep freezer -- and small batches are taken out for frozen shipment to scientists at U-M or other institutions who can use them in their research.
