Area of Science:

  • Developmental biology
  • Neuroscience
  • Biomedical imaging

Background:

  • Current imaging techniques like light microscopy lack depth penetration for observing deep embryonic structures.
  • Magnetic Resonance Imaging (MRI) offers deep tissue penetration but typically lacks cellular resolution and speed.

Purpose of the Study:

  • To develop and assess in vivo Magnetic Resonance Imaging (MRI) microscopy for high-resolution, deep-tissue imaging of vertebrate embryonic development.
  • To overcome limitations of existing techniques for observing cellular events within developing organisms.

Main Methods:

  • Exploration of technical challenges in achieving in vivo MRI microscopy.
  • Application of developed techniques to image cells within developing frog embryos over several days.
