    <p>Цель: Изучение процессов регенерации при лечении местных лучевых поражений (МЛП) кожи мезенхимальными стволовыми клетками (МСК) слизистой ткани десны человека, культуральной средой (КС) и концентратом кондиционированной среды (ККС) на лабораторных животных.&#13;
Материал и методы: В исследование включено 80 белых крыс-самцов линии Wistar массой 210 ± 30 г в возрасте 8–12 нед, рандомизированых случайным образом на 4 группы (по 20 животных в каждой): контроль (К), животные не получали терапию; контроль с введением концентрата культуральной среды (КС) трехкратно на 1, 14 и 21 сут; введение МСК в дозе 2 млн на 1 кг трехкратно на 1, 14 и 21 сут; введение ККС в расчетной дозе 2 млн клеток на 1 кг трехкратно на 1, 14 и 21 сут. Каждое лабораторное животное наблюдали 17 раз: на 1, 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105, 112-е сут после моделирования ожога. Проводили гистологическое (окраска гематоксилином-эозином) и иммуногистохимическое (СD31, СD68, VEGF) исследования. Моделирование МЛП проводили на рентгеновской установке в дозе 110 Гр. Культивировали МСК по стандартной методике до 3–5 пассажа, осуществляли забор кондиционированной среды и концентрировали ее в 10 раз. Иммунофенотип МСК (CD34, CD45, CD90, CD105, CD73, HLA-DR) и жизнеспособность (7‑ADD) определяли с помощью проточной цитофлуориметрии. &#13;
Результаты: При планиметрической оценке измененной кожи животных на 7 сут в группе ККС площадь была достоверно больше по сравнению с группами К, МСК, КС (р ≤ 0,05). В группе КС на 14-е сут площадь открытой раневой поверхности и язвы с 28 до 42-х сут была достоверно меньше по сравнению с группами К, МСК и ККС (р ≤ 0,05). В группе К с 42 до 77-х сут наблюдения отмечалось увеличение площади язвы кожи по сравнению с группами КС и ККС (р ≤ 0,05). На 112-е сут полное заживление язвы кожи в группе КС отмечалось у 40 %, в группе МСК – у 60 %, а в группе ККС – лишь у 20 % животных, а в группе К не регистрировалось. Выраженная экспрессия маркера VEGF в эндотелиальных клетках и клетках стромы отмечалась в группах К и КС на 28-е сут и в группах МСК и ККС на 112-е сут.&#13;
Заключение: Таким образом, все использованные методы лечения, включая 3-кратное введение КС, МСК и ККС в дозе 2 млн на 1 кг, были эффективны при МЛП кожи и приводили к сокращению площади поражения, ускоренному заживлению язвы, улучшению регенеративных процессов. Кроме того, применение МСК приводило к улучшению васкуляризации и уменьшению воспалительных процессов в очаге лучевого поражения.</p>

    <p>Purpose: To study the regeneration processes in the treatment of radiation skin lesions with the mesenchymal stem cells (MSC) derived from human gingiva and their conditional medium concentrate (CCM) during animal studies.&#13;
Material and methods: The study includes 80 white male Wistar rats weighing 210 ± 30 g at the age of 8–12 weeks, randomized into 4 groups (20 animals in each): control group (C), animal did not receive treatment; control with the introduction of the conditional medium concentrate (CCM) three times on days 1, 14 and 21; the introduction of MSC in a dose of 2 million cells per 1 kg three times on days 1, 14 and 21; the introduction of CCM in the estimated dose of 2 million cells per 1 kg three times on days 1, 14 and 21. Radiation burn simulation was performed (using on an X-ray unit at a dose of 110 Gy) and each animal was observed 17 times: at days 1, 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105 and 112. Histological (stained with hematoxylin-eosin) and immunohistochemical (CD31, CD68, and VEGF) studies were performed. MSC was cultivated according to the standard procedure up to passages 3–5, the conditioned medium was collected and concentrated 10 times. The MSC immunophenotype (CD34, CD45, CD90, CD105, CD73, HLA-DR) and viability (7-ADD) were determined using flow cytometry.&#13;
Results: Under the assessment of the animal skin on the day 7 in the CCM group, the area was significantly larger compared to the C, MSC, CM groups (р ≤ 0.05). In the CM group on the day 14 the area of the open wound surface and ulcers from day 28 to day 42 was significantly less, compared with the C, MSC and CCM groups (р ≤ 0.05). In group C, from 42 to 77 days of observation, an increase in the area of skin ulcers was observed compared with the CM and CCM groups (р ≤ 0.05). On the day 112, healing of skin ulcers in the CM group was observed in 40 %, in the MSC group in 60 %, and only in 20 % of animals in the CCM group, and in the C group it was not registered. Expression of VEGF marker on endothelial cells and stromal cells was observed in groups C and CM on day 28 and in groups MSCs and CCM on day 112. On the 28th day in the MSC group, the average number of vessels (CD31) in the field of view was 6.0, and on day 112 it was 12.75, р ≤ 0.05, in the CCM group – 19.10 and 28.6, respectively, р ≤ 0.05. An increase in the number of macrophages (CD68) was found in group C from 28 to 112 days (11.6 and 24.73, р ≤ 0.05), and in the CM group the decrease was 22.1 and 13.07, respectively, р ≤ 0.05.&#13;
Conclusion: Thus, all used treatment modes of radiation skin lesions, including 3-fold administration of CM, MSC and CCM at a dose of 2 million cells per 1 kg, were effective and resulted in a reduction in the damage area, accelerated ulcer healing, and improvement of the regenerative processes. In addition, the use of MSCs led to the improvement of inflammatory processes’ vascularization and reduction in the radiation skin lesions.</p>
