In this Dec. 5, 2014, file photo, Dr. Mark Berman, of the Cell Surgical Network, injects a patient with a solution he says is rich in adult stem cells, at his practice in Beverly Hills, Calif. Berman’s company is the largest in the mushrooming industry of for-profit clinics that market stem cells to patients with dozens of different diseases and conditions. Critics say the businesses have flourished due to a lack of government oversight. (AP Photo/Raquel Dillion)
