(Submitter supplied) In this work we aimed to evaluate how the three-dimensionality of an engineered scaffold, concieved to emulate the stem cell niche, can influence the whole gene expression profile of mesenchymal stem cells. We performed a differential expression analysis, comparing the transcriptome of MSCs grown in 3D Nichoids with that of MSCs grown on 2D Nichoids, a structure with the same grid geometry, except for the overall tickness which allows a spreading expansion of cells. more...

(Submitter supplied) 3D cell cultures are becoming more and more important in the field of regenerative medicine due to their ability to mimic the cellular physiological microenvironment. Among the different types of 3D scaffolds, we focus on the Nichoid, a miniaturized scaffold with a structure inspired by the natural staminal niche. The Nichoid can activate cellular responses simply by subjecting the cells to mechanical stimuli. more...

(Submitter supplied) MSCs in vivo have a markedly different three-dimensioanal (3D) niche compared to the traditional two-dimensional (2D) culture in vitro. We used microarrays to detail the global difference of gene expression between MSCs cultured on 3D and 2D matrixes

(Submitter supplied) Obvious advantages of 3D cell culture model are the cell morphology better reflecting tissue cell morphology, the formation of zones of i) active proliferation, ii) quiescent viable cell zone and iii) necrotic zone, as well as formation of nutrition, oxygen and drug gradients better reflecting cellular environment in tissue. Nevertheless the 3D cultures are a model still not resembling full complexity of tumor tissue environment in vivo. more...

(Submitter supplied) The extracellular matrix (ECM), as one of the key components of tumor microenvironment has a high impact on cancer development and highly influences tumor cell features. ECM contribute not only structural support to growing tumor cells, but also affect other cellular functions such as cell differentiation, migration, survival or proliferation. Moreover, gene and protein expression levels are regulated in cell-ECM interaction dependent manner. more...

(Submitter supplied) Development of systems allowing the maintenance of native properties of mesenchymal stromal cells (MSC) is a critical challenge for studying physiological functions of skeletal progenitors, as well as towards cellular therapy and regenerative medicine applications. Conventional stem cell culture in monolayer on plastic dishes (2D) is associated with progressive loss of functionality, likely due to the absence of a biomimetic microenvironment and the selection of adherent populations. more...
