Title: Different radiosensitivities of mast-cell precursors in the bone marrow and skin of mice

Abstract

Although tissue mast cells are derived from the bone marrow, some descendants of bone marrow-derived precursors retain the ability to proliferate and differentiate into mast cells even after localization in the skin. The purpose of the present study was to determine the D/sub 0/ values for mast-cell precursors in the bone marrow and those localized in the skin. Bone marrow cells were removed from (WB X C57BL/6)F/sub 1/+/+ mice after various doses of irradiation and injected into the skin of the congenic W/W/sup v/ mice which were genetically without mast cells. Radiosensitivity of mast-cell precursors in the bone marrow was evaluated by determining the proportion of the injection sites at which mast cells did not appear. For the assay of the radiosensitivity of mast-cell precursors localized in the skin, pieces of skin were removed from beige C57BL/6 (bg/sup J//bg/sup J/, Chediak-Higashi syndrome) mice after various doses of irradiation and grafted onto the backs of the normal C57BL/6 mice. Radiosensitivity of mast-cell precursors in the skin was evaluated by determining the decrease of beige-type mast cells which possessed giant granules. Mast-cell precursors in the bone marrow were much more radiosenitive than those localized in the skin. D/sup 0/ value was aboutmore » 100 rad for the former and about 800 rad for the latter.« less

  • Although tissue mast cells are derived from the bone marrow, some descendants of bone marrow-derived precursors retain the ability to proliferate and differentiate into mast cells even after localization in the skin. The purpose of the present study was to determine the D0 values for mast-cell precursors in the bone marrow and those localized in the skin. Bone marrow cells were removed from (WB X C57BL/6)F1-+/+ mice after various doses of irradiation and injected into the skin of the congenic W/Wv mice which were genetically without mast cells. Radiosensitivity of mast-cell precursors in the bone marrow was evaluated by determiningmore » the proportion of the injection sites at which mast cells did not appear. For the assay of the radiosensitivity of mast-cell precursors localized in the skin, pieces of skin were removed from beige C57BL/6 (bgJ/bgJ. Chediak-Higashi syndrome) mice after various doses of irradiation and grafted onto the back of the normal C57BL/6 mice. Radiosensitivity of mast-cell precursors in the skin was evaluated by determining the decrease of beige-type mast cells which possessed giant granules. Mast-cell precursors in the bone marrow were much more radiosensitive than those localized in the skin. D0 value was about 100 rad for the former and about 800 rad for the latter.« less
  • Two different types of cells in the peritoneal cavity of mice produce mast cell colonies in methylcellulose. Large mast cell colonies are produced by bone marrow-derived precursors resembling lymphoid cells by light microscopy (L-CFU-Mast), whereas medium and small mast cell colonies are produced by morphologically identifiable mast cells (M-CFU-Mast and S-CFU-Mast, respectively). In the present study we eradicated peritoneal mast cells by intraperitoneal (IP) injection of distilled water. The regeneration process was investigated to clarify the relationship between L-CFU-Mast, M-CFU-Mast, and S-CFU-Mast. After injection of distilled water, M-CFU-Mast and S-CFU-Mast disappeared, but L-CFU-Mast increased, and then M-CFU-Mast and S-CFU-Mast appeared,more » suggesting the presence of a hierarchic relationship. When purified peritoneal mast cells were injected two days after the water injection, the L-CFU-Mast did not increase. In the peritoneal cavity of WBB6F1-+/+ mice that had been lethally irradiated and rescued by bone marrow cells of C57BL/6-bgJ/bgJ (beige, Chediak-Higashi syndrome) mice, L-CFU-Mast were of bgJ/bgJ type, but M-CFU-Mast and S-CFU-Mast were of +/+ type. The injection of distilled water to the radiation chimeras resulted in the development of bgJ/bgJ-type M-CFU-Mast and then S-CFU-Mast. The presence of mast cells appeared to suppress the recruitment of L-CFU-Mast from the bloodstream and to inhibit the differentiation of L-CFU-Mast to M-CFU-Mast.« less
  • A study was made to determine whether the maturation of murine cutaneous mast cells from stem cells depends on an intact bone marrow microenvironment. Normal bone marrow cells (+/+) were infused into 2 groups of mast cell-deficient mice: WBB6F1-W/Wv mice and /sup 89/Sr-pretreated W/Wv mice. /sup 89/Sr is a long-lived bone-seeking radioisotope which provides continuous irradiation of the marrow and thereby ablates the marrow microenvironment. Skin biopsies revealed that the /sup 89/Sr-pretreated mice and the controls had repopulated their skin with mast cells equally well. Natural killer cell function was significantly depressed in the /sup 89/Sr-treated mice, confirming that themore » marrow microenvironment had been functionally altered. It appears that, although the precursors for cutaneous mast cells are marrow derived, they do not need an intact marrow microenvironment for maturation.« less
  • Interleukin (IL)-3-dependent mouse bone marrow-derived mast cells (BMMCs) are an important model for studying the function of mucosal-type mast cells. In the present study, BMMCs were successfully immortalized by cell fusion using a hypoxanthine-aminopterin-thymidine medium-sensitive variant of P815 mouse mastocytoma (P815-6TgR) as a partner cell line. The established mouse mast cell hybridomas (MMCHs) expressed {alpha}, {beta}, and {gamma} subunits of high-affinity immunoglobulin E (IgE) receptor (Fc{epsilon}RI) and possessed cytoplasmic granules devoid of or partially filled with electron-dense material. Four independent MMCH clones continuously proliferated without supplemental exogenous IL-3 and showed a degranulation response on stimulation with IgE+antigen. Furthermore, histamine synthesismore » and release by degranulation were confirmed in MMCH-D5, a MMCH clone that showed the strongest degranulation response. MMCH-D5 exhibited elevated levels of IL-3, IL-4, IL-13, granulocyte-macrophage colony-stimulating factor, tumor necrosis factor (TNF)-{alpha}, and cyclooxygenase 2, and production of prostaglandin D{sub 2} and leukotriene C{sub 4} in response to IgE-induced stimulation. MMCH clones also expressed Toll-like receptors (TLRs) 1, 2, 4, and 6 and showed elevated levels of TNF-{alpha} expression in response to stimulation with TLR2 and TLR4 ligands. The MMCHs established using this method should be suitable for studies on Fc{epsilon}RI- and TLR-mediated effector functions of mast cells.« less
  • Host-vs-graft activity presents a major obstacle for transplantation of T cell-depleted bone marrow in HLA-mismatched patients. In a primate model, conditioned exactly like leukemia patients, it was shown that residual host clonable T cells, as well as alloreactive cytotoxic precursors, were present in peripheral blood and spleen after completion of cytoreduction. We have now extended this study in a mouse model for allogeneic bone marrow transplantation. C/sub 3/H/HeJ mice were treated by 9 Gy total body irradiation (TBI), and 24 hr later their spleen cells were cultured in the presence of T cell growth factor and phytohemagglutinin according to themore » limit dilution procedure. After 7 days of culture the average frequency of clonable cells was 2.5 X 10(-3) compared with 37 X 10(-3) in the spleens of normal mice. The T cell derivation of the growing cells was ascertained by complement-mediated cytotoxicity with anti-Thy-1 as well as with anti-Lyt-2 and anti-Ly-3T4. In parallel, we found that the initial engraftment rate of bone marrow allograft in mice given 9 Gy TBI was lower than that found in recipients of syngeneic marrow. The initial engraftment rate was measured by the number of colony-forming units in the spleen and by splenic uptake of /sup 125/IUdR. A slight increase in TBI from 9 Gy to 11 Gy markedly reduced the difference in the number of spleen colony-forming units or the IUdR uptake between recipients of allogeneic and syngeneic bone marrow. This increase in TBI also coincided with eradication of detectable clonable T cells. Moreover, in mice transplanted with T cell-depleted bone marrow after 9 Gy TBI, we also demonstrate that cytotoxicity against donor-type target cells is present in the spleen 10 to 14 days posttransplantation, whereas in mice treated by 11 Gy TBI such alloreactivity could not be detected.« less
