Fat stem cells regenerate cartilage in osteoarthritis



Dr. Bui Hong Thien Khanh, head of orthopedics at the Ho Chi Minh City Medicine and Pharmacy University Hospital, told Vietweek that as of last January his hospital had performed the trials on 21 patients with OA of the knees.
Doctors use a needle to harvest about 100cc of patients’ abdominal fat, and extract stem cells from the adipose tissues with a centrifuge. The patients’ blood is extracted and also placed in the centrifuge to get platelet-rich plasma.
The stem cells and platelet-rich plasma are then put under a low-energy laser before being injected into the degenerative joints.
Khanh said both the plasma and low-energy laser help activate dormant stem cells, which, after activation, can differentiate into cartilage cells to replace the lost ones, and stimulate the damaged cartilage tissues to regenerate.
He said reviews six to 18 months after the procedure showed that all the patients had reduced pain, could walk normally, and did not suffer from other complications.
An MRI (Magnetic resonance imaging) six months after the operation showed the fibrillation in their cartilage had declined and the damaged cartilage had become thicker, he said.
Pretty interesting findings.
