news- what does this mean

desmond? anyone? this seems like a good step, i don't understand why multiplying dermal papillae cells is not possible yet, isn't that what christiano did this past year? didn't they take DP cells, multiply them, and group them together? This stuff is confusing, it seems like all the pieces are in place but nothing is being done on humans.
