   <abstract xml:lang="ru">
    <p>Изучена чувствительность культивируемых мезенхимальных стромальных стволовых клеток (МСК), полученных из костного мозга мыши, к облучению протонами с энергией 32 МэВ и относительная биологическая эффективность (ОБЭ) протонов в диапазоне низких доз. Выживаемость МСК после облучения оценивали по изменению количества клеток и их клоногенной активности. Дозиметрию протонного излучения проводили с использованием радиохромной пленки ЕВТ3, которую подвергали облучению в тех же условиях, что и облучаемые клетки. Для этого образцы пленки размещали в аналогичных цилиндрических пробирках в культуральной среде, моделируя условия облучения суспензии клеток. Распределение энерговыделения протонов при прохождении пучка частиц через исследуемые образцы рассчитывали с использованием программы SRIM-2013-Pro. Показано, что как общее количество МСК, так и количество МСК, способных к пролиферации, снижается с увеличением дозы облучения протонами. При этом клетки, обладающие клоногенной активностью, более чувствительны к инактивации протонами, чем общая популяция облученных МСК. При сравнении чувствительности клоногенной активности МСК к облучению протонами и гамма-квантами, показано, что клетки в диапазоне низких доз (от 0,15 до 0,6 Гр) более чувствительны к действию протонов. При расчете ОБЭ протонов по полученным данным показано возрастание этого показателя в указанном диапазоне доз от 1,54 до 2,07.</p>

    <p>The sensitivity of cultured mesenchymal stromal stem cells (MSC) obtained from mouse bone marrow to irradiation with 32 MeV protons and the relative biological efficiency (RBE) of protons in the low dose range were studied. The survival of MSCs after irradiation was assessed by the change in the number of cells and in their clonogenic activity. Dosimetry of proton radiation was performed using an EBT3 radiochromic film, which was irradiated under the same conditions as the irradiated cells. For this, the film samples were placed in similar cylindrical tubes in the culture medium, simulating the conditions for irradiation of the cell suspension. The distribution of the energy release of protons during the passage of a particle beam through the samples under study was calculated using the SRIM-2013-Pro software. It has been shown that both the total number of MSCs and the number of MSCs capable of proliferation decrease with an increase in the proton irradiation dose. Moreover, cells with clonogenic activity are more sensitive to inactivation by protons than the general population of irradiated MSCs. When comparing the sensitivity of the clonogenic activity of MSCs to irradiation with protons and gamma rays, it was shown that cells in the range of low doses (from 0.15 to 0.6 Gy) are more sensitive to the action of protons. When calculating the RBE of protons from the data obtained, an increase in this indicator was shown in the indicated dose range from 1.54 to 2.07.</p>
