Cartilage Formation In Vivo Using High Concentration Collagen-Based Bioink with MSC and Decellularized ECM Granules.

The aim of this study was to verify the applicability of high-concentration collagen-based bioink with MSC (ADSC) and decellularized ECM granules for the formation of cartilage tissue de novo after subcutaneous implantation of the scaffolds in rats. The printability of the bioink (4% collagen, 2.5% decellularized ECM granules, derived via 280 μm sieve) was shown.

Bioprinting of Cartilage with Bioink Based on High-Concentration Collagen and Chondrocytes.

The study was aimed at the applicability of a bioink based on 4% collagen and chondrocytes for cartilage formation. Extrusion-based bioprinting was used for the biofabrication. The printing parameters were tuned to obtain stable material flow.

[Vacuum-therapy of postoperative sternomediastinitis].

Aim: To estimate the results of sternomediastinitis management using vacuum-therapy compared with conventional treatment of such wounds.

Material And Methods: We have retrospectively analyzed data for the period from January 2007 to October 2014. The study enrolled 79 patients with infectious complication after cardiac surgery.
