Hypothesis
To characterize cyan fluorescent protein (CFP) expression in the retina of the thy1-CFP transgenic mouse line.
Conclusion
The thy1-CFP mouse line is highly useful for studies requiring the identification of ganglion cells.
Supporting Evidence
- CFP was extensively expressed in the inner retina, primarily in the ganglion cell layer.
- The density of CFP-expressing cells in the ganglion cell layer ranged from 1827±280 to 3589±470 cells/mm2.
- Immunohistochemical studies demonstrated colocalization of CFP with ganglion cell markers.
- About 99.7% of CFP-expressing cells contained DAPI, indicating they are neurons.
- CFP expression was confirmed in cholinergic amacrine cells.
Takeaway
This study looked at how a special protein that glows blue is found in certain cells in the eyes of mice, helping scientists see and study these cells better.
Methodology
CFP expression was characterized using morphometric methods and immunohistochemistry with various antibodies.
Limitations
The study did not correct for tissue shrinkage during the mounting process.
Participant Demographics
Adult Thy1-CFP C57BL/6J transgenic mice.
