The results of research conducted by a Xeltis-led team on the effect of matrix bioabsorbtion speed on amount, composition and mechanical properties of restored native tissue have been published in peer-reviewed journal Tissue Engineering Part A. Findings from the in vitro study showed that slow-bioabsorbable matrices help restore more tissue and with better mechanical integrity in the long-term compared to fast-bioabsorbable ones and may therefore be a preferable option for cardiovascular prostheses to enable tissue restoration.
