Area of Science:

  • Developmental Biology
  • Teratology
  • Animal Models

Background:

  • Neural Tube Defects (NTD) are disabling congenital malformations.
  • Investigating NTD requires suitable experimental models.
  • The chick embryo offers a potential model for NTD research.

Purpose of the Study:

  • To establish and validate a chick embryo model for inducing Neural Tube Defects (NTD).
  • To assess the suitability of this model for studying human-like NTD, particularly spina bifida.

Main Methods:

  • Domestic hen eggs (Gallus gallus) were incubated and subjected to albumen aspiration at 24 hours.
  • Embryos were recovered and examined on incubation days 8, 10, and 14.
  • Malformations, specifically NTD, were documented and analyzed.

Main Results:

  • A significant percentage of treated embryos survived (45%) and exhibited malformations (12%).
  • Neural Tube Defects (NTD) were induced in 6% of embryos, including open myelomeningocele, meningocele, and encephalocele.
  • The induced NTD closely resembled human NTD anatomy.

Conclusions:

  • The chick embryo model provides a simple, inexpensive, and effective method for inducing NTD.
  • This model is suitable for further research into the mechanisms and potential treatments of NTD, including spina bifida.
  • The anatomical similarity to human malformations makes this model highly relevant for translational research.
