dc.description.abstract | Assembly of pluripotent stem cells to initiate self-organized tissue formation on engineered scaffolds is an important process in stem cell engineering. Pluripotent stem cells are known to exist in diverse pluripotency states, with heterogeneous subpopulations exhibiting differential gene expression levels, but how such diverse pluripotency states orchestrate tissue formation is still an unrevealed question. In this study, using microstructured adhesion-limiting substrates, we aimed to clarify the contribution to self-organized layer formation by mouse embryonic stem cells in different pluripotency states: ground and naïve state. We found that while ground state cells as well as sorted REX1-high expression cells formed discontinuous cell layers with limited lateral spread, naïve state cells could successfully self-organize to form a continuous layer by progressive mesh closure within 3 days. Using sequential immunofluorescence microscopy to examine the mesh closure process, we found that KRT8+ cells were particularly localized around unfilled holes, occasionally bridging the holes in a manner suggestive of their role in the closure process. These results highlight that compared with ground state cells, naïve state cells possess a higher capability to contribute to self-organized layer formation by mesh closure. Thus, this study provides insights with implications for the application of stem cells in scaffold-based tissue engineering. | en |
