Human pluripotent stem cells (hPSCs) are a promising cell source for tissue engineering and regenerative medicine, especially in the field of neurobiology. Neural differentiation protocols have been developed to differentiate hPSCs into specific neural cells, but these predominantly rely on biochemical cues. Recently, differentiation protocols have incorporated topographical cues to increase the total neuronal yield.

The limiting factors for current methods include being labor-intensive, time-consuming and expensive. In this study, we hypothesize that the substrate topography, with optimal geometry and dimension, can modulate the neural fate of hESCs and enhance the efficiency of differentiation.

One of the most commonly used methods for identification is flow cytometry. Many flow cytometry applications use antibodies to detect the amount of antigen present on/in a cell.

Understanding the interaction between stem cells and the extracellular substrate will be crucial in controlling stem cell differentiation for regenerative medicine applications. One of the biophysical properties of the microenvironment is substrate topology, which has been demonstrated to be an important mediator of stem cell lineage regulation.
