Hypothesis
What are the cellular targets of BMP signaling during kidney organogenesis?
Conclusion
The study identifies that nephron progenitor cells are refractory to SMAD dependent BMP signaling, while BMP signaling is active in other kidney structures.
Supporting Evidence
- The BRE-lacZ reporter accurately maps BMP signaling in the developing kidney.
- SMAD dependent BMP signaling is active in collecting duct trunks but not tips.
- Nephron progenitor cells show little to no BMP signaling activation.
Takeaway
This study shows how certain proteins help the kidney develop, and that some kidney cells don't respond to these proteins like we thought they would.
Methodology
The study used a transgenic reporter mouse model to visualize BMP signaling activity in developing kidneys.
Limitations
The study may not account for all signaling pathways involved in kidney development.
