Appliance of magnetic nanoparticles and magnetic fields can increase efficacy of cell transplantation. Superparamagnetic iron oxide nanoparticles (SPION) is a most prospective type of magnetic nanoparticles for magnetically controlled targeting of cells in vivo. In the investigation human fetal fibroblasts were labeled with citrate stabilized SPION (SPION-Cit) that refer to anionic magnetic nanoparticles. 100, 200, 300 and 500 дд Fe/ml doses of magnetic nanoparticles and incubation times of 1, 2 and 3 h were used. The effectiveness of magnetic labeling of cells was evaluated by magnetophoresis in a special chamber using disk NdFeB magnet with diameter of 6 mm and thickness of 3 mm and field induction of 0,255 T: magnetophoretic velocity of magnetized cells in magnetic field gradient was assessed and their magnetic susceptibility was calculated. Viability of magnetically labeled cells was evaluated by trypan blue staining and MTT-test. The value of magnetic susceptibility of magnetically labeled fetal fibroblasts was dose and incubation time depended. A capture distance of labeled cell with the magnet was in a range of 3-4 mm. Magnetophoretic movement of control fibroblasts was not observed. Viability of labeled cells was not decreased substantially in ranges of nanoparticles concentrations 100-300 дд Fe/ml and incubation times 1-3 h. In the concentration of 500 дд Fe/ml partial cell death and exfoliation of cell layer from culture flask observed (signs of low grade exfoliation also observed in the labeling conditions of 300 дд Fe/ml for 3 h). According to our data, most optimal conditions for magnetic labeling of human fetal fibroblast with SPION-Cit is particles concentration 100 дд Fe/ml for 3 h, which provides the capture distance of labeled cells with the magnet about 4 mm.</p></abstract><trans-abstract xml:lang="ru"><p>Клеточная трансплантология является актуальным и активно развивающимся направлением регенеративной медицины, но эффективность её часто остаётся относительно низкой при ряде показаний для применения. С помощью магнитных наночастиц и магнитных полей можно повысить эффективность трансплантации клеток. Суперпарамагнитные наночастицы оксида железа (SPION) являются наиболее перспективными для магнитоуправляемой доставки клеток in vivo. Цель настоящего исследования - оптимизация методики магнитной маркировки клеток с помощью SPION, стабилизированных цитратом (SPION-Cit), относящихся к анионным магнитным наночастицам. Объектом магнитного маркирования были выбраны фетальные фибробласты человека (ФФЧ) в качестве модели здоровых клеток человека. Дозы наночастиц составляли 100, 200, 300 и 500 мкг Fe/мл; время инкубации 1, 2 и 3 ч. Эффективность магнитной маркировки клеток оценивали с помощью магнитофореза в специальной камере с использованием дискового NdFeB магнита диаметром 6 мм и толщиной 3 мм, с индукцией 0,255 Тл: определяли скорость движения магнитомаркированных клеток в градиентном магнитном поле и рассчитывали их магнитную восприимчивость. Жизнеспособность магнитомаркированных фибробластов оценивали методом окрашивания трипановым синим и с помощью МТТ-теста. Величина магнитной восприимчивости магнитомаркированных ФФЧ зависела от дозы наночастиц и времени инкубации. Дальность захвата магнитомаркированных клеток магнитом была в пределах 3-4 мм. Магнитофоретиче-ское движение контрольных ФФЧ отсутствовало. Магнитомаркированные ФФЧ в пределах концентраций наночастиц 100-300 мкг Fe/мл и времени инкубации 1-3 ч. сохраняли жизнеспособность. При концентрации 500 мкг Fe/мл наблюдали частичную гибель клеток и отслоение клеточного пласта от поверхности культурального флакона (начальные признаки отслоения наблюдали при режиме мечения 300 мкг Fe/мл, 3 ч.). По результатам исследования были определены оптимальные параметры магнитного маркирования ФФЧ SPION-Cit - концентрация наночастиц 100 мкг Fe/мл, время инкубации 3 ч., обеспечивающие дальность захвата клеток магнитом на расстоянии 4 мм.</p></trans-abstract><kwd-group xml:lang="en"><kwd>superparamagnetic iron oxide nanoparticles</kwd><kwd>human fetal fibroblasts</kwd><kwd>magnetophoresis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>суперпарамагнитные наночастицы оксида железа</kwd><kwd>фетальные фибробласты человека</kwd><kwd>магни-тофорез</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>von Bahr L., Batsis I., Moll G. еЬ al.
