  • silk fibroin hyaluronan scaffolds for human mesenchymal Stem Cell Culture in tissue engineering
    Biomaterials, 2009
    Co-Authors: Marcos Garciafuentes, Lorenz Meinel, Anne J Meinel, Monika Hilbe, Hans P. Merkle
    Abstract:

    The design of new bioactive scaffolds mimicking the physiologic environment present during tissue formation is an important frontier in biomaterials research. Herein, we evaluated scaffolds prepared from blends of two biopolymers: silk fibroin and hyaluronan. Our rationale was that such blends would allow the combination of silk fibroin's superior mechanical properties with the biological characteristics of hyaluronan. We prepared scaffolds with porous microstructures by freeze-drying aqueous solutions of silk fibroin and hyaluronan and subsequent incubation in methanol to induce water insolubility of silk fibroin. Hyaluronan acted as an efficient porogenic excipient for the silk fibroin scaffolding process, allowing the formation of microporous structures within the scaffolds under mild processing conditions. Mesenchymal Stem Cells were seeded on silk fibroin/hyaluronan scaffolds and Cultured for three weeks. Histology of the constructs after Cell Culture showed enhanced Cellular ingrowth into silk fibroin/hyaluronan scaffolds as compared to plain silk fibroin scaffolds. In the presence of tissue-inductive stimuli, in vitro Stem Cell Culture on silk fibroin/hyaluronan scaffolds resulted in more efficient tissue formation when measured by glycosaminoglycan and type-I and type-III collagen gene expression, as compared to plain silk fibroin scaffolds. In conclusion, our data encourages further exploration of silk fibroin/hyaluronan scaffolds as biomimetic platform for mesenchymal Stem Cells in tissue engineering.
