В связи с этим разработка биомедицинских клеточных продуктов (БМКП) для восстановления хрящевой ткани достаточно актуальна, а использование органоидных технологий наиболее приближено к условиям нативной ткани. Согласно требованиям законодательства РФ, в рамках доклинических исследований необходимо изучение биораспределения, характеризующего миграционный потенциал клеток, их тропность к тканям организма при имплантации. Целью работы было исследовать биораспределение нового БМКП на основе хондроцитов человека в виде хондросфер после подкожной имплантации мышам линии Balb/c nude. На первом этапе осуществляли имплантацию 12 мышам, а также введение физиологического раствора 12 контрольным животным. В течение 90 дней проводили взвешивание и наблюдение, а затем выводили мышей из эксперимента для получения образцов органов и тканей для гистологического анализа импланта, оценки его состоятельности, интеграции. На втором этапе изучали биораспределение методом ПЦР для выявления ДНК человека в образцах тканей и органов. Хондросферы успешно интегрировались в окружающие ткани зоны инокуляции, формировали хрящевую ткань. Статистически значимых (p &lt; 0,05) изменений в весе не зафиксировали. В образцах из зоны имплантации хондросфер была выявлена ДНК человека, которую не обнаруживали в других органах и тканях. БМКП через 90 дней после имплантации демонстрировал отсутствие биораспределения в другие ткани и органы мышей, что свидетельствует о безопасности разрабатываемого продукта.</p></abstract><trans-abstract xml:lang="en"><p>Despite the prospects of the approach to cell therapy of cartilage damage in humans involving autologous chondrocytes, similar technologies are just beginning to be introduced into medical practice in the Russian Federation. In this regard, the development of biomedical cell products (BCPs) for cartilage tissue repair is quite topical, while the use of organoid technology is the most close to the native tissue conditions. According to requirements of legislation of the Russian Federation, it is necessary to assess biodistribution characterizing migration potential of the cells, their tropism for body tissues following implantation within the framework of preclinical trials. The study was aimed to assess biodistribution of novel BCP based on human chondrocytes in the form of chondrospheres after subcutaneous implantation in Balb/c nude mice. Implantation to 12 mice was performed during the first phase, along with administration of saline to 12 control animals. Weighting and follow-up were conducted for 90 days. Then mice were withdrawn from the experiment to collect samples of organs and tissues for histological analysis of the implant, estimation of its viability, integration. During the second phase biodistribution was assessed by PCR in order to detect human DNA in the organ and tissue samples. Chondrospheres successfully integrated in the tissues surrounding the inoculation zones and formed cartilage tissue. No significant (p &lt; 0.05) changes in weight were reported. No human DNA found in chondrosphere implantation zones was detected in the samples collected from other organs and tissues. BCP demonstrated no biodistribution across other tissues and organs of mice 90 days after implantation, which suggested that the product developed was safe.
