Area of Science:

  • Developmental biology
  • Biomedical imaging
  • Genetics

Background:

  • Optical coherence tomography (OCT) is a non-invasive imaging modality.
  • Xenopus tadpoles are a valuable model for studying development.
  • Efficient phenotyping is crucial for genetic and teratogenic studies.

Purpose of the Study:

  • To establish OCT as a method for in vivo phenotyping of Xenopus tadpoles.
  • To assess the utility of OCT for studying gene/teratogen effects on craniofacial and cardiac development.
  • To develop a rapid imaging workflow for Xenopus studies.

Main Methods:

  • Utilized OCT imaging to visualize craniocardiac structures in Xenopus tadpoles.
  • Acquired 2D and 3D cross-sectional images in real time.
  • Employed Doppler imaging to assess cardiac blood flow.

Main Results:

  • OCT provided high-resolution, label-free imaging of dynamic morphology.
  • Demonstrated reproducible and efficient in vivo cardiac and facial phenotyping.
  • Showcased the ability to identify gene/teratogen phenotype relationships rapidly.

Conclusions:

  • OCT is an efficient, non-destructive method for comprehensive Xenopus tadpole phenotyping.
  • The OCT Xenopus workflow allows rapid screening of genetic and teratogenic effects.
  • This approach facilitates the transition from genomic screening to mechanistic studies.
