Перспективы использования скелета морских губок семейства Aplysinidae и мезенхимных стромальных клеток в тканевой инженерии
Development of the new types of tissue engineered structures is one of the promising trends of current biotechnology. The study was directed to the assessment of prospects for the application of chitin-based skeletons derived from marine sponges of Aplysinidae family ( Aplysina fulva and Aplysina aerophoba ) for creation of bioengineered constructs based on human me senchymal stromal cells. After cleaning and demineralization procedures, sponge skeletons appeared as three-dimensional macroporous matrices formed by intersecting chitin fibrils. After seeding into chitin-based matrices the cells were attached to the surface of the fibrils and were able to spread and proliferate. Mesenchymal stromal cells within Aplysina fulva differentiated into osteogenic and adipogenic directions under the influence of appropriate inductors. Demineralized skeletons derived from marine sponges of Aplysinidae family could be used as scaffolds for mesenchymal stromal cells which provides new opportunities for the creation of adipose and bone tissue engineered structures.
