Kaede mice for in vivo monitoring of cell migration
B6.Cg-Tg(CAG-tdKaede)15Utr (RBRC05737)

Kaede mice are transgenic strains expressing photoconversion fluorescent protein “Kaede (derived from a kind of stony coral)” under the control of CAG promoter. Kaede mice emit green fluorescence constitutively in all the cells. After irradiation with violet light, green-to-red photoconversion occurs only in exposure site. This distinctive photoconversion is not affected in the cellular function. Moreover, in cells with the fewer number of divisions, red fluorescent signal is observed for comparative long time. Therefore, these strains are known to be useful for both labelling of the specific cells and in vivo visualization of the cell migration. So far, Kaede mice have been utilized mainly in immunological research. For example, these were contributed to reveal immune cellular movement between organs or tissues under some environments (virus infection [3], disease onset [4], tumor infiltration [5], etc.). In addition, these approaches were divergent. Not only the analysis of original Kaede mice but also mate experiments with the other gene-modified mice or production of bone marrow chimeric mice have been reported. Cell migration monitoring by photoconversion is an attractive tool for a wide variety of research fields. We expect more effective utilization of these strains. |
