Water contact angle data and FTIR data of stem cell/tenocyte co-culture-derived secretome releasing electrospun tube; and adhesion data of fully transected and sutured rabbit Achilles tendons three weeks post-operation under application of such a tub

Tendon ruptures may result in unsatisfactory outcomes, even after long rehabilitation programs and careful return to daily activities and sports. One major problem after a tendon rupture is the fibrotic adhesion formation to the adjacent tissue, which hampers proper motion and may end up in a permanent reduced range of motion. Following a cell-free approach, we cultivated rabbit adipose-derived stem cells (ASCs) and rabbit Achilles tenocytes in a ratio of 3:1 and incorporated the secretome harvested from this co-culture into an emulsion electrospun tubular DegraPol® fiber mesh. These tubes were characterized by thestatic and dynamic water contact angles and by FTIR spectra, with a comparison to tubes without secretome incorporation (control). Furthermore, we present adhesion data from an in vivo experiment, where these tubes were implanted around a fully transected rabbit Achilles tendon after suture at 3 weeks post-operation.
