New York & Pittsburgh – July 11, 2017 – RenovaCare, Inc., (OTCQB: RCAR), has announced that its approach to isolating a patient’s own stem cells for subsequent spray onto burns and wounds has been validated by researchers in ‘Differentiation’, a leading peer-reviewed scientific publication. According to their findings, the methodology, which has been adopted by RenovaCare, successfully isolates those specific cell populations with the greatest regenerative capacity to support the growth of fully-functioning skin.
Today’s announcement follows recent highlights from an independent analysis of treatment results on a variety of wide-area and severe burn injuries published in Burns, the peer-reviewed Journal of the International Society for Burn Injuries. The treatment method, adopted by RenovaCare, involved isolating and spraying the patient’s own skin stem cells on the burn wounds, and it is the technology underlying the company’s patented CellMist™ and SkinGun™.
RenovaCare harvests a patient’s stem cells from a small area of skin, as little as one-inch square. These cells are placed in a water-based suspension and delicately sprayed onto the wound using the RenovaCare SkinGun™, where the cells begin growing new skin.
As in the case of state trooper Matt Uram, one of dozens of burn victims treated with autologous skin stem cell spray, patients are able to leave the hospital within only a few days rather than the many weeks required by alternative treatments such as in-vitro cultured epithelial grafts.
In contrast to the speed and effectiveness of the RenovaCare procedure — taking as little as 90-minutes — in-vitro cultured grafts require harvesting cells from a patient, which are then transported to a specialized external laboratory where they take weeks to form sheets of skin. These fragile sheets must then be sent back to the hospital for surgical stitching onto a patient’s wounds, a process that is complicated, time-consuming and expensive.
“It’s very exciting to have this scientific validation that our approach is ideal for rapid and natural skin regeneration,” explained Mr. Thomas Bold, President and CEO of RenovaCare, Inc. “We’ve always had confidence that our methodology isolates the body’s most regenerative cell population before spray application with our ultra-gentle SkinGun™.”
In the 2015 article published in ‘Differentiation’, researchers identified the advantages of freshly-isolated cells and compared their regenerative properties against the concept of culturing skin cells, used to grow sheets of skin.
Findings demonstrate that, under the tested conditions, freshly-isolated skin cells have far greater regenerative capacity than cells which have been repeatedly cultured. Cultured cells lose specific cell populations which support skin regeneration, necessary to healing.
In the RenovaCare approach, adopted from the study, freshly isolated cells derived from the basal layer grow both in size and number and include rapid-cycling cells responsible for quick healing. The high presence of these cells assures entirely natural regeneration of the skin without the use of external chemical support, growth factors, and drugs — important advantages highlighted by RenovaCare.
According to authors of the ‘Differentiation’ publication, the approach of applying freshly isolated stem cells to the wound is, “A concept that is thought to preserve the proliferative and regenerative capabilities of basal layer derived cells for the patient’s wound healing in a more physiological way than applying the cells to the same wound only after several weeks of in vitro culture.”
The paper further concludes that by directly applying these freshly-isolated cells onto the wound, the patient’s own body can provide the nutrients and vascular support needed in order to promote skin regeneration.

Study authors, Dr. Roger Esteban-Vives and Dr. Jörg Gerlach currently have a financial interest in the SkinGun™ spray-grafting technology through payments from RenovaCare, Inc. Dr. Esteban-Vives, currently Director of Cell Sciences at RenovaCare, Inc., was a postdoctoral fellow at the University of Pittsburgh when this work was conducted and did not have such financial interest at that time.
Burns aims to foster the exchange of information among all engaged in preventing and treating the effects of burns. The journal focuses on clinical, scientific, and social aspects of these injuries and covers the prevention of the injury, the epidemiology of such injuries, and all aspects of treatment including development of new techniques and technologies and verification of existing ones. Regular features include clinical and scientific papers, state of the art reviews, and descriptions of burn-care in practice.
