JF - Frontiers in Bioengineering and Biotechnology N2 - There is continual demand for animal models that allow a quantitative assessment of angiogenic properties of biomaterials, therapies, and pharmaceuticals. In its simplest form, this is done by subcutaneous material implantation and subsequent vessel counting which usually omits spatial data. We have refined an implantation model and paired it with a computational analytic routine which outputs not only vessel count but also vessel density, distribution, and vessel penetration depth, that relies on a centric vessel as a reference point. We have successfully validated our model by characterizing the angiogenic potential of a fibrin matrix in conjunction with recombinant human vascular endothelial growth factor (rhVEGF165). The inferior epigastric vascular pedicles of rats were sheathed with silicone tubes, which were subsequently filled with 0.2 ml of fibrin and different doses of rhVEGF165, centrically embedding the vessels. Over 4 weeks, tissue samples were harvested and subsequently immunohistologically stained and computationally analyzed. The model was able to detect variations over the angiogenic potentials of growth factor spiked fibrin matrices. Adding 20 ng of rhVEGF165 resulted in a significant increase in vasculature while 200 ng of rhVEGF165 did not improve vascular growth. Vascularized tissue volume increased during the first week and vascular density increased during the second week. Total vessel count increased significantly and exhibited a peak after 2 weeks which was followed by a resorption of vasculature by week 4. In summary, a simple implantation model to study in vivo vascularization with only a minimal workload attached was enhanced to include morphologic data of the emerging vascular tree.

JF - Journal of Tissue Engineering and Regenerative Medicine N2 - Treatment of peripheral nerve injuries has evolved over the past several decades to include the use of sophisticated new materials endowed with trophic and topographical cues that are essential for in vivo nerve fibre regeneration. In this research, we explored the use of an advanced design strategy for peripheral nerve repair, using biological and semi-synthetic hydrogels that enable controlled environmental stimuli to regenerate neurons and glial cells in a rat sciatic nerve resection model. The provisional nerve growth conduits were composed of either natural fibrin or adducts of synthetic polyethylene glycol and fibrinogen or gelatin. A photo-patterning technique was further applied to these 3D hydrogel biomaterials, in the form of laser-ablated microchannels, to provide contact guidance for unidirectional growth following sciatic nerve injury. We tested the regeneration capacity of subcritical nerve gap injuries in rats treated with photo-patterned materials and compared these with injuries treated with unpatterned hydrogels, either stiff or compliant. Among the factors tested were shear modulus, biological composition, and micropatterning of the materials. The microchannel guidance patterns, combined with appropriately matched degradation and stiffness properties of the material, proved most essential for the uniform tissue propagation during the nerve regeneration process.

JF - Muscle, ligaments and tendons Journal N2 - Introduction: Due to limitations of ACL reconstruction, primary ACL repair has recently regained research interest. Although abandoned in the past, primary repair with conservation of the original ligament demonstrates considerable advantages compared to reconstruction. We hypothesized that early repair, strictly limited to patients with a proximal ACL rupture and excellent tissue quality of the remaining ACL stump, would lead to equal revision rates and subjective outcomes as reported for ACL reconstruction after a minimum of 5 years. Methods: In this questionnaire study, patients who had a primary ACL repair between 2002 and 2009 were invited to participate. Besides any potential revision surgery, the Tegner activity scale and the Knee Injury and Osteoarthritis Outcome Score were included in the evaluation. Results: Out of 1912 patients who had ACL related surgery during the observation period, 221 (11.4%) had a primary ACL repair. 60 patients (61 knees) were available for follow-up. In 2/61 (3.3%) cases ACL revision surgery was performed and one patient had meniscus surgery of the affected side. The median Tegner activity scale was 6 (range, 3 to 10). The mean KOOS subscores were 88.8% (Function/Sports), 86.6% (Quality of life), 94.6 (Symptoms), 94.0 (Pain) and 97.0 (Activities of Daily Living). Conclusion: Primary ACL repair, strictly limited to proximal ruptures with good tissue quality leads to revision rates and subjective outcome comparable to ACL reconstruction. Level of evidence: IV.
