Hypothesis
Can spectral domain optical coherence tomography (SD-OCT) provide high-resolution imaging of zebrafish embryos without sacrificing them?
Conclusion
SD-OCT allows for noninvasive, high-speed imaging of zebrafish embryos, enabling detailed observation of their development.
Supporting Evidence
- SD-OCT provided ultra-high resolution visualization of the eye, brain, heart, ear, and spine of the developing embryo as early as 24 hpf.
- Repeated line scanning with averaging optimized the visualization of static and dynamic structures.
- Structural defects caused by a mutation in the nok gene were readily observed.
Takeaway
Scientists used a special camera to take super clear pictures of baby fish without hurting them, so they could see how they grow.
Methodology
Zebrafish embryos were imaged at various developmental stages using SD-OCT, allowing for 3D visualization of internal structures.
Limitations
Imaging may be affected by motion artifacts and the presence of highly scattering tissues can obscure deeper structures.
Participant Demographics
Wildtype and nok gene mutant zebrafish embryos at 24, 48, 72, and 120 hours post fertilization.
