Разработка техники трансплантации SD-клеточных сфероидов ретинального пигментного эпителия (РПЭ) на глазах экспериментальных животных (кролики).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. SD-сфероиды РПЭ для последующей трансплантации создавали с использованием агарозных планшетов (3D Petri Dishes, Microtissue, США). Фенотип полученных клеточных культур исследовали с помощью иммуноцитохимического анализа (лазерный сканирующий конфокальный микроскоп «Fluo View FV10i», Olympus, Япония). Всем экспериментальным животным (кролики породы шиншилла, n = 10) выполняли витрэктомию - 2500 резов в минуту, вакуум 600 мм рт. ст. (Alcon, Accurus, США), ретинотомию и субретинально вводили сфероиды РПЭ (MicroDose injection kit 1 ml, Med One, США). Методы послеоперационного контроля: ультразвуковое В-сканирование глаза (Ultrasonic UD-6000, Tomey, Япония) и оптическая когерентная томография - ОКТ (Askin Spectralis, Heidelberg engineering, Германия). Глазные яблоки энуклеировали на 7, 10, 14, 20-е сутки для последующего гистологического исследования.</p></sec><sec><title>Результаты</title><p>Результаты. Иммуноцитохимическое окрашивание выявило сохранение фенотипа РПЭ в форме 3D-сфе-роидов. В послеоперационном периоде у всех экспериментальных животных по данным ультразвукового В-сканирования и ОКТ отмечалась схожая клиническая картина: отек и плоская отслойка сетчатки в зоне оперативного вмешательства. По мере наблюдения сетчатка прилегала и отек сетчатки уменьшался. Также, по данным ОКТ, субретинально обнаруживались округлые конгломераты диаметром от 60 до 80 мкм - предположительно 3D-сфероиды РПЭ. По данным гистологического исследования отмечалась адгезия сфероидов РПЭ к сосудистой оболочке с последующим распластыванием и образованием нового клеточного слоя по мере увеличения сроков наблюдения.</p></sec><sec><title>Заключение</title><p>Заключение. Предложенная технология культивирования кроличьего РПЭ с последующим конструированием 3D-сфероидов позволяет сохранить эпителиальный фенотип клеток. Разработанная хирургическая техника трансплантации РПЭ является приемлемой и может использоваться для дальнейших экспериментальных исследований с целью внедрения в клиническую практику.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. This research is aimed to devise the technique for transplantation of 3D spheroids retinal pigment epithelium (RPE) in the experimental animal’s eyes (rabbits).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 3D spheroids of RPE for subsequent transplantation were created using agarose tablets (3D Petri Dishes, Microtissue, USA). The phenotype of the obtained cell cultures was studied by immunocytochemical tests (laser scanning confocal microscope “Fluo View FV10i”, Olympus, Japan). Vitrectomy - 2500 cuts per minute, vacuum 600 mm Hg (Alcon, Accurus, USA) was performed on all rabbits (n = 10). Then, we made retinotomy and injected spheroids in subretinal space (MicroDose injection kit 1 ml, Med One, USA). The following methods of control: ultrasound B-scan (Ultrasonic UD-6000, Tomey, Japan) and optical coherence tomography (OCT), (Askin Spectralis, Heidelberg engineering, Germany). Eyes were enucleated for histological examination on 7, 10, 14 and 20 days.</p></sec><sec><title>Results</title><p>Results. Immunocytochemical tests revealed preservation of the RPE epithelial phenotype in 3D spheroids. Clinical map was similar in all experimental animals - during the first 7 days after surgery we saw cystic edema and flat retinal detachment in the surgery area. As we observed, the retina was adjoining and retinal edema was decreasing. Also, on day 3, 7 and 10 on OCT we saw subretinal round conglomerates with a diameter of 60 to 80 µm - presumably RPE 3D spheroids. According to histological findings, there was observed adhesion of the RPE spheroids to the choroid with subsequent spreading and formation of new cell layer with the increase of observation periods.</p></sec><sec><title>Conclusion</title><p>Conclusion. The proposed technology of cultivation of rabbit RPE with subsequent construction of 3D spheroids allows to preserve the epithelial phenotype of cells. The developed surgical technique of RPE transplantation is acceptable and can be used for further experimental studies to be implemented in clinical practice.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ретинальный пигментный эпителий</kwd><kwd>SD-сфероиды</kwd><kwd>возрастная макулярная дегенерация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>retinal pigment epithelium</kwd><kwd>3D spheroid</kwd><kwd>age-related macular degeneration</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Балашова ЛМ.Витаминно-минеральные комплексы и здоровье глаз.
