Abstract
The dynamic migratory behavior of human mesenchymal stem cells (hMSCs) has a significant impact on the epigenetic profiles that determine fate choice and lineage commitment during differentiation. Here we report a novel approach to enhance repeated migration-driven epigenetic memory which induces cardiomyogenic differentiation on a dendrimer surface with fifth generation (G5). Cells exhibited the formation of cell aggregates on the G5 surface through active migration with morphological changes, and these aggregates showed strong expression of the cardiac-specific marker cardiac troponin T (cTnT) at 10 days. When cell aggregates were passaged onto a fresh G5 surface over three passages of 40 days, the expression levels of the multiple cardiac-specific markers including GATA4, NKX2.5, MYH7, and TNNT2 were higher compared to those passaged as single cells. To investigate whether cardiomyogenic differentiation of hMSCs was enhanced by repeated aggregate migration-driven epigenetic memory, cells on the G5 surface were reseeded onto a fresh G5 surface during three passages using aggregate-based and single cell-based passage methods. Analyses of global changes in H3 histone modifications exhibited pattern of increased H3K9ac and H3K27me3, and decreased H3K9me3 in aggregate-based passage cultures during three passages. However, the pattern of their histone modification on the PS surface was repeated after the initialization and reformation during three passages in single cell-based passage cultures. Thus, repetitive aggregate migratory behavior during aggregate-based passage led to a greater degree of histone modification, as well as gene expression changes suggestive of cardiomyogenic differentiation.

Abstract
Understanding of the fundamental mechanisms of epigenetic modification in the migration of human mesenchymal stem cells (hMSCs) provides surface design strategies for controlling self-renewal and lineage commitment. We investigated the mechanism underlying muscle lineage switching of hMSCs by cellular and nuclear deformation during cell migration on polyamidoamine dendrimer surfaces. With an increase in the dendrimer generation number, cells exhibited increased nuclear deformation and decreased lamin A/C and lamin B1 expression. Analysis of two repressive modifications (H3K9me3 and H3K27me3) and one activating modification (H3K9ac) revealed that H3K9me3 was suppressed, and H3K9ac and H3K27me3 were upregulated in the cultures on a higher-generation dendrimer surface. This induced significant hMSC lineage switching to smooth, skeletal, and cardiac muscle lineages. Thus, reorganizations of the nuclear lamina and cytoskeleton related to migration changes on dendrimer surfaces are responsible for the integrated regulation of histone modifications in hMSCs, thereby shifting the cells from the multipotent state to muscle lineages. These findings improve our understanding of the role of epigenetic modification in cell migration and provide new insights into how designed surfaces can be applied as cell-instructive materials in the field of biomaterial-guided differentiation of hMSCs to different cell types. STATEMENT OF SIGNIFICANCE: Stem cell engineering strategies currently applied the mechanical cues that emerge from cellular microenvironment to regulate stem cell behaviour. This study significantly improved our understanding of the mechanotransduction mechanism involving cell-ECM and cytoskeleton-nucleoskeleton interactions, and of nuclear genome regulation based on cellular responses to biomaterial modifications. The new insights into how the physical environment on a culture surface influences cell behaviour improve our understanding of mechanical control mechanisms of the interactions of cells with the extracellular environment. Our findings are also expected to contribute to and play an essential role in the development of future material strategies for creating artificial cell-instructive niches.

Abstract
BACKGROUND Dedifferentiation of chondrocytes during cell expansion is one of the barriers in tissue construction for cartilage repair. To understand chondrocyte behavior and improve cell expansion in monolayer culture, this study investigated the effects of morphological changes and cellular aggregation on the maintenance of chondrogenic capacity by observing the expression patterns of chondrogenic (collagen type II and aggrecan) and dedifferentiation (collagen type I) markers. Primary human chondrocytes were cultured on either a polystyrene surface (PS) or a polyamidoamine dendrimer surface with a fifth-generation (G5) dendron structure to create a one-step process of cell expansion and the maintenance of chondrogenic activities prior to the construction of cell sheets. RESULTS During the first two passages (P0 - P2), the relative mRNA level of collagen type II decreased in all cultures, while that of collagen type I increased. Remarkably, the level of collagen type II was higher and aggrecan was retained in the chondrocytes, forming cell aggregates and showing some round-shaped cells with less production of stress fibers on the G5 surface compared to fibroblast-like chondrocytes with abundant stress fibers on the PS surface. The numbers of P2 chondrocytes on the G5 and PS surfaces were nearly the same and sufficient for construction of chondrocyte sheets using a temperature-responsive plate. Without a supporting material during cell sheet manipulation, chondrocyte sheets spontaneously detached and exhibited a honeycomb-like structure of stress fibers. Unlike the chondrocyte sheets constructed from cells on the PS surface, the chondrocyte sheets from cells on the G5 surface had higher chondrogenic activities, as evidenced by the high expression of chondrogenic markers and the low expression of dedifferentiation markers. CONCLUSIONS The one-step process of cell expansion and maintenance of chondrogenic activity could be obtained using the G5 surface. Human chondrocyte sheets were successfully constructed with high chondrogenic activity. These findings may lead to an alternative cultivation technique for human chondrocytes that offers high clinical potential in autologous chondrocyte implantation.
