Although GATA-binding transcription factors (GATA-1 and GATA-2) are strongly expressed in cultured mast cells (CMCs), their expression in mast cells within tissues has not been reported. We examined the expression of GATA-1 and GATA-2 in skin tissues of mice using Northern blot analysis and in situ hybridization. mRNA for GATA-2 but not for GATA-1 was expressed in skin mast cells of WB-+/+ embryos between days 15 and 17 postcoitum (pc). The expression was downregulated on and after day 18 pc. Skin mast cells did not express GATA-2 after birth either. When the number of skin mast cells was compared with the number of GATA-2 mRNA-expressing cells, GATA-2 mRNA appeared to be expressed by mast cells only when the number was increasing. When the mRNA expression of high-affinity IgE receptor beta-subunit and mast cell carboxypeptidase A was used as differentiation markers, the expression of these mRNAs continued even after the downregulation of GATA-2 expression. To clarify the relationship of the proliferation and GATA-2 expression, proliferating CMCs derived from WBB6F1-+/+ mice were transplanted into the peritoneal cavity of mast cell-deficient WBB6F1-W/Wv mice. The CMCs stopped both the proliferation and GATA-2 expression after the transplantation, suggesting the association of these two parameters in mast cells within tissues of mice.
