Main Results:

Multicolor labeling and multispectral imaging provided unique spectral identities for individual cells, improving in vivo identification and tracking.
Simulations showed improved cell counting with 3-color labeling compared to 1-color labeling at higher cell densities.
Combined membrane and nuclear labeling enhanced analysis of cell interactions while preserving movement tracking.
Multispectral imaging reduced acquisition and analysis time for large 3D datasets.

Conclusions:

Multicolor cell labeling and multispectral imaging create a cellular fingerprint for precise cell positioning within embryos.
These spectral imaging methods offer a powerful toolbox for detailed in vivo cell dynamics research.
