Hypothesis
Proper initiation of spleen formation is key for the formation of the gastric lobe of the pancreas.
Conclusion
The study shows that spleen organogenesis is crucial for the normal development of the gastric lobe of the pancreas.
Supporting Evidence
- The gastric lobe begins to form by growth from the dorsal pancreatic epithelium around embryonic day 13.5.
- From embryonic day 15.5, the gastric lobe constitutes more than 10% of the total pancreatic epithelial volume.
- Mice with disturbed spleen development show impaired gastric lobe formation.
- Markers for multipotent progenitors are delayed in the gastric lobe compared to other pancreatic lobes.
Takeaway
The pancreas needs the spleen to grow properly, just like how plants need good soil to grow strong.
Methodology
The study used optical projection tomography to analyze pancreatic growth dynamics in mice.
Limitations
The study could not establish an organ culture system to manipulate gastric lobe morphogenesis.
Participant Demographics
The study involved various mouse mutants with impaired spleen development.
