Area of Science:

  • Developmental Biology
  • Regenerative Medicine
  • Biomaterials Science

Background:

  • Human organoid model systems are crucial for studying human development and disease.
  • Advancing organoid technology requires innovative platforms for enhanced control and functionality.
  • Piezoelectric materials offer potential for sensing and actuating biological systems.

Purpose of the Study:

  • To evaluate the compatibility of piezoelectric nanofibers with human intestinal organoid (HIO) generation.
  • To explore the potential of piezoelectric materials for sensing and actuating organoids.
  • To establish a proof of concept for electrical stimulation of organoids using ultrasound.

Main Methods:

  • Human pluripotent stem cells were differentiated into spheroids on piezoelectric nanofiber scaffolds using the HIO protocol.
  • Organoids were cultured and characterized for morphology, structure, and patterning.
  • Ultrasound stimulation was applied to HIOs cultured on nanofiber scaffolds to assess cellular response.

Main Results:

  • Piezoelectric nanofibers accelerated spheroid formation by 3 days compared to conventional methods.
  • HIOs grown on scaffolds showed normal development, transplantability, and tissue organization.
  • Ultrasound stimulation of HIOs on scaffolds increased cellular proliferation without detrimental effects.

Conclusions:

  • Piezoelectric nanofibers are compatible with HIO generation and promote accelerated development.
  • The integrated system enables on-demand electrical stimulation of organoids via ultrasound.
  • This technology presents a customizable platform for regenerative medicine applications.
