When a cell changes state, you want to know why. Could the surface be changing the answer? SENCE™ supplies a specified, ready-to-use hydrogel surface and built-in protein-binding chemistry, in plates and coverslips. Start with two stiffness conditions. Match the cells, medium and timing. Specify the same matrix protein, and verify its attachment and presentation, so those differences don't quietly become a second experiment. Follow an early signalling readout, then the cell state and function you care about. A change in cell shape can start an investigation; a functional measurement helps explain its importance. The published StemBond platform separated stiffness from matrix tethering. In mouse pluripotent stem cells, softer conditions also changed signalling linked to cell identity. That establishes a powerful experimental question to bring into your own system. If the response depends on stiffness, investigate that pathway. Next, hold stiffness constant and evaluate a selected matrix parameter, with the other interface properties controlled and checked. Through Early Access, work with StemBond to bring the product and practical knowledge into a focused experiment for your research.
