Values represent the number of mast cells in each combination of donors and recipients. Results are mean ± SE of 5 mice and are given as the number per 103 peritoneal cells, number per mm2 mesentery and spleen, and number per cm stomach and skin. The number of mast cells in each combination of donors and recipients was less than 0.1 for WBB6F1-tg/tg to WBB6F1-W/Wv. Before the transplantation, WBB6F1-W/Wv mice were irradiated with 2 Gy, and WBB6F1-tg/tg mice with 8 Gy. P < .01 by t test when compared to the values observed in WBB6F1-W/Wv mice transplanted from WBB6F1-+/+ donors.
