Abstract (original English)
In regenerative medicine, human cell replacement therapy offers great potential, especially by cell types differentiated from immunologically and ethically unproblematic mesenchymal stem cells (MSCs). In terms of an appropriate carrier material, collagen scaffolds with homogeneous pore size of 65μm were optimal for cell seeding and cultivating. However, before clinical application and transplantation of MSC-derived cells in scaffolds, the safety and efficiency, but also possible interference in differentiation due to the material must be preclinically tested. The common marmoset monkey (Callithrix jacchus) is a preferable non-human primate animal model for this aim due to its genetic and physiological similarities to the human. Marmoset bone marrow-derived MSCs were successfully isolated, cultured and differentiated in suspension into adipogenic, osteogenic and chondrogenic lineages by defined factors. The differentiation capability could be determined by FACS. Specific marker genes for all three cell types could be detected by RT-PCR. Furthermore, MSCs seeded on collagen I scaffolds differentiated in adipogenic lineage showed after 28days of differentiation high cell viability and homogenous distribution on the material which was validated by calcein AM and EthD staining. As proof of adipogenic cells, the intracellular lipid vesicles in the cells were stained with Oil Red O. T
