Tissue engineered pre-vascularized buccal mucosa equivalents utilizing a primary triculture of epithelial cells, endothelial cells and fibroblasts
Artificial generated buccal mucosa equivalents are a promising approach for the reconstruction of urethral defects. Limiting in this approach is a poor blood vessel supply after transplantation, resulting in increased morbidity and necrosis. We generated a pre-vascularized buccal mucosa equivalent in a tri-culture of primary buccal epithelial cells, fibroblasts and microvascular endothelial cells, using a native collagen membrane as a scaffold. A successful pre-vascularization and dense formation of capillary-like structures at superficial areas was demonstrated. The lumen size of pre-formed blood vessels corresponded to the capillary size in vivo (10-30 μm). Comparing native with a highly …
Primary Mucosal Epithelial Cell Cultivation: A Reliable and Accelerated Isolation
We illustrate a reliable and accelerated isolation routine for mucosal epithelial cells, which thereupon can be used for soft tissue engineering. This is highly important in the field of soft tissue engineering because mucosal equivalents are frequently usable in several surgical fields like gynecology, urology, otorhinolaryngology, ophthalmology, maxillofacial surgery, and many others. In this context the isolation of mucosal epithelial cells suitable for tissue engineering is mandatory. The reliable cultivation of mucosal or skin epithelial cells is challenging and there is currently no reproducible method. We demonstrate a solution for this problem by developing an accelerated and nevert…
