Protocole

hPSC maintenance and expansion
This protocol maintains and expands human pluripotent stem cells under feeder-free, chemically defined conditions using E8 medium and vitronectin-coated culture surfaces; the readout is sustained adherent colony growth with undifferentiated morphology and retained pluripotency-marker expression during serial passaging. E8-based hPSC culture relies on defined soluble factors and matrix-dependent adhesion rather than feeder cells; vitronectin supports hPSC attachment through integrin-mediated interactions, and EDTA passaging dissociates colonies as small aggregates without enzymatic digestion, centrifugation, or routine ROCK-inhibitor treatment.
