En tre-dimensionelle clonogenic analyse, der giver pancreas-lignende stamceller til at differentiere til insulin-udtrykkende kolonier er beskrevet. Denne metode benytter sig af semi-faste medier indeholdende methylcellulose, Matrigel og vækst faktorer, og hvor enkelt progenitorer formere sig og differentiere<em> In vitro</em>, Tillader kvantificering af antallet af funktionelle stamceller i en befolkning.
