Stem cells show promise for stroke
Stem cells extracted from patients’ bone marrow have shown promising results for stroke therapy in a first pilot study for humans.
UK researchers provided the treatment to five patients who had experienced a severe anterior circulation ischemic stroke in the previous seven days.
All five showed improvements in clinical tests and reductions in lesion volume during a six-month follow-up period.
In the trial, four of the patients were alive and three were independent after six months.
The therapy uses CD34+ hematopoietic stem/progenitor cells sourced from the patient’s own bone marrow, which were delivered by catheter angiography into the ipsilesional middle cerebral artery.
The cells are thought to release
