A quantitative assessment of post-natal development in CF rats
Acta Anatomica
|January 1, 1978
Summary
Post-natal development in CF rats reveals distinct growth patterns. Weight gain shows two peaks, while other measurements exhibit unique growth trajectories and changes in rate.
Area of Science:
- Developmental Biology
- Animal Models
Background:
- Understanding post-natal development is crucial for identifying growth anomalies.
- Cystic Fibrosis (CF) models provide insights into disease-related developmental impacts.
Purpose of the Study:
- To anthropometrically characterize post-natal development in CF rats.
- To analyze growth rate patterns for various physical parameters.
Main Methods:
- Daily measurements of weight, CR length, tail length, and patello-calcaneal length in CF rats from birth to day 75.
- Calculation of daily growth rates for each parameter.
- Assessment of robustness and correlation between parameters and age.
Main Results:
- Weight gain exhibited two distinct peaks (days 26-30 and 56-60).
- CR length and tail length showed single growth rate peaks.
- Patello-calcaneal length demonstrated an initial decline followed by stabilization.
- Growth curves indicated exponential growth with sudden rate changes.
Conclusions:
- CF rat development follows a complex, non-linear pattern with specific inflection points.
- Body weight and derived robustness metrics correlate strongly with developmental progression.
- These findings highlight critical periods of altered growth in CF models.
