Cornea to Lens Transdifferentiation in Xenopus laevis

Sample size: 60 publication 10 minutes Evidence: high

Author Information

Hypothesis

BMP signalling is required for lens regeneration in Xenopus laevis.

Conclusion

The study shows that BMP and Wnt signalling pathways are crucial for the transdifferentiation of corneal cells into lens cells in Xenopus laevis.

Supporting Evidence

  • BMP signalling is essential for lens regeneration.
  • Wnt signalling components are upregulated during lens regeneration.
  • Pitx genes, which may be Wnt targets, are upregulated during lens regeneration.

Takeaway

When the lens is removed from a frog's eye, the cornea can turn into a new lens, and this process needs certain signals from the body to happen.

Methodology

The study used a transgenic approach and microarray analysis to investigate gene expression during lens regeneration.

Limitations

The study only examined a single time point in the regeneration process.

Participant Demographics

Xenopus laevis tadpoles were used in the experiments.
