Hypothesis
Follistatin-like 1 (Fstl1) is essential for skeletal and lung organogenesis during mouse development.
Conclusion
Fstl1 is crucial for normal skeletal and lung development, and its absence leads to neonatal lethality due to respiratory distress.
Supporting Evidence
- Fstl1 is expressed early in development and is crucial for lung and skeletal formation.
- Fstl1 knockout mice exhibit severe respiratory distress and die at birth.
- The absence of Fstl1 leads to multiple skeletal defects, including abnormal limb and spine development.
Takeaway
Fstl1 helps build bones and lungs in baby mice, and without it, the babies can't breathe and die right after birth.
Methodology
Conditional knockout mice for Fstl1 were created, and their development was analyzed for skeletal and lung defects.
Limitations
The study primarily focuses on mouse models, which may not fully represent human development.
