EosFP has been used to track cell movements during embryonic development of Xenopus laevis. At the two-cell/ early gastrula stage, capped mRNA coding for a dimeric EosFP (d2EosFP) was injected into cells and locally photoconverted using fluorescence microscopy.  These fluorescent embryos demonstrated the dynamics of cell movement during neurulation. EosFP was found in part of the notochord which shows the possibility of EosFP to be used in fate-mapping experiments.
