| Outline of Final Research Achievements |
In silico analysis suggested that Fzd5 and LRP6, which are the receptors for Wnt7a, might be one of the candidate markers for the endometrial stem cells. Both Fzd5- and LRP-positive cells, however, did not reconstruct the endometrium. We then investigated the CD93, which is preferentially expressed in side population cells, but we did not find an association between CD93 and stemness. We next attempted to develop a novel mouse model of endometrial implantation using a lentivirus system to introduce bioluminescent, fluorescent, and cell surface marker genes and to address the in vivo endometrial stem cell activity. Firstly we used human primary endometrial cells, but they showed a very low implantation rate. We, therefore, used a human endometrial cancer cell line and immortalized human endometrial cells and found that they both showed a relatively higher success rate.
