Healing at the Cellular Level

icon

Effective healing and the formation of robust skin requires the presence and products of keratinocytes, fibroblasts and melanocytes1,2

  1. Keratinocytes: Upon acute skin injury, keratinocytes at the wound edge become activated, turning into migratory, hyperproliferative cells that produce and secrete signaling polypeptides and extracellular matrix components. The leading-edge keratinocytes migrate into the wound bed whilst those behind begin to proliferate to ensure an adequate supply of cells for wound closure.1,3,4,5
  2. Fibroblasts: At the margin, they migrate into the wound bed and synthesize and deposit extracellular proteins necessary for connective tissue formation to support cellular ingrowth.1
  3. Melanocytes: The presence of these pigment-producing cells allows for restoration, over time, of normal pigmentation.6

RECELL provides a cellular suspension of three phenotypes: keratinocytes, fibroblasts and melanocytes.7

These isolated single cells stimulate healing throughout the wound bed rather than being limited to the wound edge.7

Important Safety Information

Indications for Use: The RECELL® Autologous Cell Harvesting Device is indicated for the treatment of acute thermal burn wounds in patients 18 years of age and older. The RECELL® device is used by an appropriately-licensed healthcare professional at the patient’s point of care to prepare autologous Regenerative Epidermal Suspension (RES™) for direct application to acute partial-thickness thermal burn wounds or application in combination with meshed autografting for acute full-thickness thermal burn wounds.

Contraindications: RECELL® is contraindicated for: the treatment of wounds clinically diagnosed as infected or with necrotic tissue, the treatment of patients with a known hypersensitivity to trypsin or compound sodium lactate (Hartmann’s) solution, patients having a known hypersensitivity to anesthetics, adrenaline/epinephrine, povidone-iodine, or chlorhexidine solutions.

Warnings: Autologous use only. Wound beds treated with a cytotoxic agent (e.g., silver sulfadiazine) should be rinsed prior to application of the cell suspension. RECELL® is provided sterile and is intended for single-use. Do not use if packaging is damaged or expired. Choose a donor site with no evidence of cellulitis or infection and process skin immediately. A skin sample should require between 15 and 30 minutes contact with Enzyme. Contact in excess of 60 minutes is not recommended. RECELL® Enzyme is animal derived and freedom from infectious agents cannot be guaranteed.

Precautions: RECELL® is not intended for use without meshed autograft for treatment of full-thickness burn wounds. The safety and effectiveness of RECELL® without meshed autograft have not been established for treatment of partial-thickness burn wounds: on the hands and articulating joints, >320 cm2, in patients with wounds totaling >20% total body surface area (TBSA). The safety and effectiveness of RECELL® with autografting have not been established for treatment of full-thickness burn wounds: on the hands and articulated joints, in patients with wounds totaling >50% TBSA.

Special Patient Populations: The safety and effectiveness of RECELL® have not been established for treatment of acute thermal partial-thickness or full-thickness burn wounds in pediatric patients younger than 18 years of age. For complete Important Safety Information, refer to Instructions For Use.
