Los ligandos de matriz extracelular se pueden patrones en hidrogeles de poliacrilamida para permitir el cultivo de células madre embrionarias humanas en colonias confinadas en sustratos compatibles. Este método se puede combinar con microscopía de fuerza de tracción y ensayos bioquímicos para examinar la interacción entre la geometría del tejido, las fuerzas generadas por células y la especificación del destino.
