Spray-on skin for burns victims: would it work for steroid victims too?

Spray-on skin for burns victims, is reported in the Telegraph: "The spray-gun which fires stem cells on to the damaged skin has already been used successfully on a dozen patients."
I wonder if it would it work for steroid victims too? The skin of steroid victims, and also the skin of victims of other prescription-drug-induced morbid obesity, becomes very thin, painful and delicate. Sometimes, for instance, the skin at their elbows completely disappears and the elbow actually pokes through! - Just try to imagine how painful that would be - and how vulnerable to infection! - Especially as most doctors are disgracefully ill-informed about drug-induced morbid obesity.
