Dr Robert Iacono tried this, with fetal stem cells, back in 1989, and since he couldn't find a hospital in the US that would permit it, he dragged his patient, one Max Truex, to a clinic in Zhengzhou, China, where he had no problem in "acquiring" fetal cells.
The Chinese and Iacono were somewhat casual about separating out the proper cells, and when the autopsy was performed, on Truex's brain, they found foetal teeth, hair, bone...
The article indicates they used adult stem cells this time.
This is different. These cells have already been started on the process of development in the desired manner.
