Precise spatial and temporal regulation of dynamic morphogen signals during human development governs the processes of cell proliferation, migration, and differentiation to form organized tissues and organs. Tissue patterns spontaneously emerge in various human pluripotent stem cell (hPSC) models. However, the lack of molecular methods for precise control over signal dynamics limits the reproducible production of tissue patterns and a mechanistic understanding of self-organization.

The fluorescent ubiquitination-based cell-cycle indicator (FUCCI) has allowed the dual-color visualization of the G and S/G /M phases in various dynamic models, but its application in hPSCs is not widely reported. In addition, lineage-specific FUCCI reporters have not yet been developed to analyze complex tissue-specific cell-cycle progression during hPSC differentiation.

The uprising of regenerative medicine converges the sight onto stem cell-biomaterial based therapy. Tissue engineering and regenerative medicine proposes the strategy of constructing spatially, mechanically, chemically and biologically designed biomaterials for stem cells to grow and differentiate.
