Hypothesis
To clarify the role of bone morphogenetic proteins (BMP-2, -4, -5) in sclera remodeling during myopia induction and their effect on sclera fibroblasts in cell culture.
Conclusion
BMP-2 might promote scleral fibroblast proliferation and differentiation, as well as help extracellular matrix synthesis potentially through the classical Smad pathway.
Supporting Evidence
- BMP-2 and BMP-5 expression were reduced in the posterior sclera of form-deprivation myopia eyes.
- Cell proliferation increased significantly when incubated with 100 ng/ml BMP-2.
- The expressions of collagen I, aggrecan, and phospho-smad1/5/8 significantly increased with BMP-2 treatment.
Takeaway
This study found that certain proteins in the eye can help cells grow and change during myopia, which is when your eyes grow too long and make it hard to see far away.
Methodology
The study used RT-PCR, western blotting, and immunofluorescence to analyze BMP expression in sclera and cultured human scleral fibroblasts.
Participant Demographics
Guinea pigs (20 total) and human scleral tissues from healthy adult donors (n=3; ages 18, 19, and 25).
