    • To determine if stem cells can be induced to self-renew and differentiate properly in engineered settings.

    Main Methods:

    • Reviewing known factors regulating stem cell maintenance and differentiation.
    • Utilizing novel bioengineered synthetic materials designed to mimic extracellular matrix components.

    Main Results:

    • Identified key factors for stem cell regulation.
    • Demonstrated potential of biomimetic materials as scaffolds for stem cell microenvironments.

    Conclusions:

    • Artificial recreation of stem cell microenvironments is a promising avenue for tissue engineering.
    • Bioengineered materials offer a viable approach to guide stem cell behavior for developmental purposes.
