AROA ECM™ is a proprietary extracellular matrix (ECM) biomaterial containing a rich and complex mix of biological molecules that is the building block for our range of soft tissue repair products.
AROA ECM™ is manufactured from the ovine (sheep) forestomach tissue, sourced exclusively from New Zealand pasture-raised animals.(1) The source tissue is minimally processed to separate tissue layers and decellularize the tissue ECM. The resulting bioscaffold technology has the structure, composition and function of the ECM that is found in all our soft tissues.(1)

Cells and the surrounding soft tissue extracellular matrix (ECM) constantly interact to modulate tissue physiology in a process called dynamic reciprocity.(1) In this process, matrix components play an important role in regulating tissue growth, maintenance and orchestrating the process of tissue regeneration. AROA ECM™ retains the authentic structure, signaling and substrates of tissue ECM to help guide tissue repair.(2, 3) Furthermore, AROA ECM™ retains the delicate micro-architecture of tissue ECM to influence the way cells attach, migrate, grow and differentiate.(4)
AROA ECM™ contains more than 150 ECM proteins that are known to be important in the healing process including structural proteins, adhesion proteins, proteoglycans, growth factors and basement membrane.(5) Components in the AROA ECM™ are also shown to attract stem cells.(6)
AROA ECM™ also contains residual vascular channels,(7) that facilitate the rapid establishment of a dense capillary network by supporting migrating endothelial cells to establish new vasculature and a robust blood supply to help build new tissue.(8)
AROA ECM™ is non-cross-linked to preserve the native matrix structure and reduce the risk of negative inflammatory responses due to cross-linking.(9) All AROA ECM™ products are shelf stable and terminally sterilized (ethylene oxide).
