Presence of mast cell precursors in peripheral blood of mice demonstrated
by parabiosis
Y Kitamura, K Hatanaka, M Murakami and H Shibata
The presence of mast cell precursors in peripheral blood was examined. The
beige C57BL/6 (bgj/bgj, Chediak-Higashi syndrome) mouse was parabiosed with
the normal C57BL/6 mouse. Mast cells containing giant granules and
originating in the beige partner appeared in the normal parabiont. A
comparable proportion of normal-mouse-type mast cells developed in the
beige parabiont as well. In spite of the low radiosensitivity of mature
mast cells, irradiation of the normal parabiont reduced the proportion of
normal-mouse-type mast cells appearing in the beige partner. It was
concluded, therefore, that the precursors of mast cells can migrate through
the bloodstream.
