Evaluation of Biocompatible Materials for Enhanced Mesenchymal Stem Cell Expansion: Collagen-Coated Alginate Microcarriers and PLGA Nanofibers

Biomolecules
Mesenchymal stem cells (MSCs) hold significant potential in regenerative medicine, tissue engineering, and cultivated meat production. However, large-scale MSC production is limited by their need for surface adherence during growth.

Next-generation sutures: Combining natural polymers and graphene for optimal wound healing

Results in Surfaces and Interfaces
Sutures are essential for wound healing. Sutures cannot influence biological healing processes; hence their efficacy is still limited. Active healing sutures must be made.

Pulsed Laser Deposition Derived Bioactive Glass-Ceramic Coatings for Enhancing the Biocompatibility of Scaffolding Materials [PDF]

Materials, 2020
The purpose of this work was to propose and evaluate a new composition for a bioactive glass-ceramic starting from the well-known 45S5 commercial product. Thus, we developed a modified version, including MgO, an oxide that turned out to induce superior mechanical properties and improved biological response.

Optimizing the Biocompatibility of PLLA Stent Materials: Strategy with Biomimetic Coating

International Journal of Nanomedicine
Poly-L-lactic acid (PLLA) stents have broad application prospects in the treatment of cardiovascular diseases due to their excellent mechanical properties and biodegradability. However, foreign body reactions caused by stent implantation remain a bottleneck that limits the clinical application of PLLA stents. To solve this problem, the biocompatibility
