| Outline of Final Research Achievements |
We previously reported that ablation of GATA2 in mouse bone marrow-derived mast cells (BMMCs) resulted in the dedifferentiation of mast cells into myeloid-like cells. In this study, we examined whether this phenomenon is also observed in vivo. Firstly, the tdTomato(+)GATA2-/-BMMCs were transplanted into the peritoneal cavity of wild type mice. Unexpectedly, however, tdTomato-positive cells were not detectable in the mesentery and peritoneal cavity of the mice 7 days following the transplantation. Secondly, we generated BAC transgenic mice harboring mast cell-specific CreERT2 and obtained 6 lines of F1 mice. Transgene copy number was estimated for 1-3 by quantitative genomic PCR. However, none of these lines express CreERT2 transgene in their peritoneal mast cells. Collectively, alternative strategies might be considered for studying GATA2-deficient mast cells in vivo.
