Pipeline: Chronic Wounds


A significant amount of chronic wounds, such as diabetic foot ulcers and venous leg ulcers, fail to heal, which can lead to pain, drainage, odor and infection as well as impacting quality of life. [1], [2] In the U.S., 49% of all skin grafts are for chronic wounds. [3]

Ongoing research with the RECELL® System for the treatment of chronic wounds helps share experiences among the medical community. Below are select case studies provided as background. For general information about our science and technology, please contact our Medical Affairs team.

CASE STUDY: Venous Leg Ulcer Chronic Wound

A 67-year-old female patient presented with peripheral arterial disease, controlled type II diabetes and a 10cm2 VLU above her right ankle that had been open for 46 weeks. Treatment with Spray-On Skin™ Cells introduced healthy skin cells, representing all normal phenotypes and wound healing factors to overcome the dysfunctional cell processes and cellular signaling that had impaired the healing of her wound. At 13 weeks post-treatment, the patient’s wound had decreased to less than 1cm2 and her pain had been reduced significantly.[13]

Caution: The use of RECELL® as a treatment of chronic wounds is limited by U.S. law to investigational use.

The RECELL® System is apprpoved by the U.S. Food and Drug Administration (FDA) for the treatment of acute thermal burns in patients 18 years and older. Click here for Important Safety and Information and Instructions for Use.
