Products addressing to basic scientific research field are derived from decellularized biological tissues. These matrices are optimal substrates for studying the biological behavior of primary cells or established cell lines on a 3D matrix. Biomaterials developed by Tissuegraft can be also enriched with bioactive molecules (antibiotics, growth factors, anticoagulants, peptides, etc.) allowing in this way, to customize substrates according to researchers needs, adapting these matrices to specific research requirements.
