Innovation that remains ahead of its time.

Even after 20 years, unmatched clinical evidence has helped Apligraf® remain the biotech healer capable of transforming wounds from chronic to acute and heal VLUs and DFUs faster.1-8

Designed to heal even in the most 
challenging environments

Apligraf is a skin substitute that looks, functions, and responds like healthy skin.2,9-11

Epidermal
layer
Dermal
layer

Epidermal layer: Contains living keratinocytes and stem cells that provide potent healing signals (growth factors/cytokines)2,10,11

Dermal layer: Contains living fibroblasts that proliferate and produce human collagen and other ECM proteins as well as growth factors/cytokines2,10,11

Keratinocyte stem cells are potent contributors to the Apligraf signaling profile

Research at Tufts Medical Center demonstrated that Apligraf contains keratinocyte stem cells.11 When compared to bilayered cellular construct generated without keratinocyte stem cells, their presence results in Apligraf generating8:

85%

more VEGF

62%

more IL-6

33%

more IL-8

IL=interleukin; VEGF=vascular endothelial growth factor

The living cells of Apligraf 
are bioactive and poised to heal9,12

In an in vitro study, meshed Apligraf was incubated over a dermal lattice for up to 5 days. By 24 hours, the wound was closed—demonstrating that Apligraf had healed itself.9

Transforming wounds from chronic to acute

The living cells of Apligraf stimulate a potent healing mechanism, help restore normal healing functions, and put the wound back on track to heal1,9,12,13

Before Apligraf treatment

  • Keratinocytes and fibroblasts unresponsive/dysfunctional14-17
  • ECM disorganized and MMPs imbalanced16,18,19
  • Growth factor signaling dysfunction20,21
  • Fibrosis present22,23

After Apligraf treatment

  • Activated keratinocytes at the wound edge1
  • Restored fibroblast function at the wound base, thus normalizing ECM production and MMP balance24
  • Corrected and regulated growth factor signaling1,9,13
  • Downregulated fibrosis formation24
