Abstract

Alzheimer's disease was induced in female Wistar rats by bilateral injection of β-amyloid fragment 1-42 into the hippocampal region. After 8 weeks, ensheathing cells of the olfactory mucosa were transplanted into the hippocampus at the same stereotactic coordinates. These cells survived for 8 weeks; large clusters of cells were observed on week 4. On weeks 3-5 after transplantation of ensheathing cells, experimental animals demonstrated a significant cognitive improvement (memory and spatial orientation). The obtained results create prerequisites for further studies of ensheathing cells as a potential cell product for personalized therapy of Alzheimer's disease.

将嗅粘膜内鞘细胞移植到海马区对恢复实验性阿尔茨海默病大鼠认知能力的影响

向雌性Wistar大鼠的海马区双侧注射β-淀粉样蛋白片段1-42，诱发阿尔茨海默病。8 周后，嗅粘膜的鞘状细胞被移植到相同立体定向坐标的海马区。这些细胞存活了8周，在第4周时观察到大的细胞簇。在移植鞘状细胞后的第 3-5 周，实验动物的认知能力（记忆力和空间定向能力）明显提高。这些结果为进一步研究作为阿尔茨海默病个性化治疗潜在细胞产品的鞘状细胞创造了先决条件。

期刊介绍： Bulletin of Experimental Biology and Medicine presents original peer reviewed research papers and brief reports on priority new research results in physiology, biochemistry, biophysics, pharmacology, immunology, microbiology, genetics, oncology, etc. Novel trends in science are covered in new sections of the journal - Biogerontology and Human Ecology - that first appeared in 2005. World scientific interest in stem cells prompted inclusion into Bulletin of Experimental Biology and Medicine a quarterly scientific journal Cell Technologies in Biology and Medicine (a new Russian Academy of Medical Sciences publication since 2005). It publishes only original papers from the leading research institutions on molecular biology of stem and progenitor cells, stem cell as the basis of gene therapy, molecular language of cell-to-cell communication, cytokines, chemokines, growth and other factors, pilot projects on clinical use of stem and progenitor cells. The Russian Volume Year is published in English from April.
