Burn / Wound Care


  • Gammagraft is a revolutionary gamma irradiated human skin allograft that can be stored at room temperature for up to two years.
  • Gammagraft is ready for use and can be applied in clinical settings without the need of costly Operating Room time!
  • Irradiation acts to preserve and sterilize both the epidermal and dermal layers of skin making it an ideal vapor barrier which easily self-adheres to a wound site alleviating pain while limiting fluid, electrolyte and protein loss.
  • Ideal for transplant patients; HIV positive patients; patients with compromised immune systems.


Indications For Use

Venus stasis ulcers

Mohs surgery sites

Diabetic foot ulcers

Skin graft donor sites

Full thickness ulcers

Areas of dermabrasion

Partial thickness wounds

Exposed pericranium and cranium

Fasciotomy sites


Temporary coverage of exposed abdominal viscera including small bowel and liver

Areas of excision which are not closed pending final pathology report

Wound healing is a multi-phase process that requires a coordinated interplay of extracellular matrix, growth factors and cells, in particular mesenchymal stem cells. Grafix is manufactured using a unique process that preserves matrix, cells and growth factors - key components to support wound healing.


Grafix is a living skin substitute allograft comprised of a biologic membrane with native mesenchymal stem cells used as a covering to promote healing and tissue repair in chronic wounds, limb salvage procedures, tendon repair and burns.

Grafix contains components that are beneficial for wound healing and tissue repair including:

  • Allograft extracellular matrix (ECM) to provide 3-dimensional support for tissue repair.
  • Growth factors and proteins to support cell migration, proliferation and maturation.
  • Mesenchymal stem cells (MSC), fibroblasts and epithelial cells to coordinate the tissue repair process and secrete a variety of growth factors.
  • Transparency allows for easy visualization of the wound bed.
  • Viability of Mesenchymal Stem Cells (MSC), Neonatal Fibroblasts and Epithelial Cells is confirmed prior to release.

Safety and Profile Testing

Grafix is regulated by the FDA under 21 CFR Part 1271 Human Cells, Tissues and Cellular and Tissue-based Products (HCT/Ps). Osiris Therapeutics, Inc. is registered with the FDA as a tissue establishment and accredited by the American Association of Tissue Banks (AATB).


Extensive donor screening, serological testing, bioburden testing and sterility testing is performed on every lot to demonstrate suitability for transplantation. Each lot is tested to confirm cellular viability post thaw.
