Использование полисахаридной подложки с нейрональным микроокружением для биоинженерии центральной нервной системы при экспериментальной спинальной травме у крыс. Иммуногистохимия спинного мозга

Abstract

The histologic and immunohistochemical assay results of the spinal cord samples of adult rats with partial damage model of a spinal cord and direct transplantation of collagen-chitosan scaffold containing progenitors of neuronal cells of the mouse and neuronal microenvironment are shown. It is established, that the replaced progenitors of neuronal cells in an area of spinal cord damage are viable within 4 weeks and make for 14 day about 34 % of cellular weight. By the end of 4 weeks progenitors of neuronal cells migrated to a nervous tissue of the recipient, the number of macroglia cells has increased. The presence of a full complex of the nervous cells growth factors is accelerates processes in area damage reconstruction. Formation of synaptic communications between neuronal cells on the border of a transplant is confirmed at absence of the expressed inflammatory reaction.

Приведены результаты гистологического и иммуноцитогистохимического анализа образцов спинного мозга взрослых крыс с моделью частичного повреждения спинного мозга и прямой трансплантации коллаген-хитозановой подложки, содержащей предшественников нейрональных клеток мыши и нейрональное микроокружение. Установлено, что пересаженные предшественники нейрональных клеток в зоне повреждения спинного мозга жизнеспособны в течение 4 недель и составляют через 14 дней около 34 % клеточной массы. К концу 4 недели предшественники нейрональных клеток мигрировали к материнской нервной ткани, число клеток макроглии увеличилось. Присутствие в подложках полного комплекса факторов роста нервных клеток ускоряет процессы реконструкции зоны повреждения. Установлено формирование межсинаптических соединений на границе трансплантата при отсутствии выраженной воспалительной реакции.
