Аннотация: Produced from В«BioplastotanВ» resorbing polyesters (linear polyesters of hydroxyl derivatives alkanoic acids) scaffolds for cell culturing such as films, pressed 3-D forms and nonwoven fabric from ultrathin fibers are characterized. Two types of polymers - a homopolymer of the 3-hydroxybutyric acid and a copolymer formed by monomers of the 3-hydroxybutyric and 3-hydroxyvalerianic acids are studied. Surface properties of developed polymer scaffolds, sterilized with autoclaving and H 2O 2-plasma processing are compared. It is shown that plasma has beneficial effects resulting in decrease of the watering contact angle and increase of surface hydrophilic properties. Positive effects of H 2O 2-plasma processing of scaffold surface on culturing cell adhesion and viability compared with autoclaving sterilization is demonstrated on NIH 3T3 line fibroblast culturing.

Заглавие : Cultivation of multipotent mesenchymal bone marrow cells on matrixes made of resorbable bioplastotan
Место публикации : Cellular Transplantation and Tissue Engineering. - 2013. - Vol. 8, Is. 1. - С. 57-65. - ISSN 1815445X (ISSN)
Ключевые слова (''Своб.индексиров.''): alkaline phosphatase--differentiation--extracellular calcium precipitates--multipotent mesenchymal stromal cells--osteopontin--resorbable bioplastotan
Аннотация: Series of cell carriers made of resorbable polyester Bioplastotan, which is a copolymer of 3- And 4-hydroxybutyric acid, are characterized in this work. With use of various technologies membranes, 3D scaffolds, and nanomatrixes formed by ultrafine fibers produced with electrostatic spinning were constructed. All types of scaffolds provide adhesion of multipotent mesenchymal stromal cells and are suitable for the cultivation and differentiation of cells in the osteoblastes, that confirmed by detection of extracellular calcium precipitates, alkaline phosphatase activity and osteopontin production in cell culture.
