My mothers' Doctor has been fighting to save her legs (diabetes, no circulation etc.) from the knees down for months. She has had partial amputation on one foot already.
A few weeks ago when I visited her there was dramatic improvement.
I asked her what miracle happened.
She said the Dr. is giving her something called "adult something cells". I verified they are stem cells with the nurses. She has no clue as to what they are. She is just happy to not be having more amputations.
One leg has no bandages for the first time since March. Her other leg is looking pinkish down to the ankle area, where the bandage starts.
It sounds like something to induce angiogenesis, the growth of blood vessels toward the site of an injury.
It's one of the tricks that cancers learn, in order to be invasive.
It could also be precursor cells for developing such blood vesels.
I have long thought that studying cancer was also a way of studying and developing human longevity.
