AI Article Synopsis
- The study aimed to find an effective method for obtaining and purifying olfactory ensheathing cells (OECs) from human fetuses using various attachment rates and intermittent NT3 application.
- Human fetal OECs exhibited positive results in P75 immunocytochemistry, showing high purity rates of approximately 95% after 9 days and 83% after 12 days of culture.
- The combined technique showed promise for simple and effective culture and purification of OECs, which could be beneficial for future research and applications.
Article Abstract
Aim: To explore a simple and pragmatic method to obtain sufficient olfactory ensheathing cells from human fetal by using different attachment rates in harvested cells with the combinating of the technique of using NT3 intermittently.
Methods: DMEM/F12 culture solution including 100 mL/L of fetal bovine serum or including NT3 was used to culture olfactory ensheathing cells intermittently every 48 h. The conditions and growth degree of OECs were observed, and P75 immunocytochemistry was used to estimate the purity of the cells.
Results: Human fetal OECs were positive after P75 immunocytochemistry. They appeared to be dipolar or tripolar cells and their processes formed a network in vitro. The purity of OECs in good conditions reached about 95% on 9 d and 83% on 12 d.
Conclusion: The method of using different attachment rates combined with the technique of using NT3 intermittently can culture and purify OECs simply and effectively.

Article Synopsis
- Alzheimer's disease was experimentally induced in female Wistar rats through injections of β-amyloid into the hippocampus.
- Following this, olfactory mucosa cells were transplanted into the same brain region and showed survival and clustering by week 4.
- The transplanted cells improved cognitive functions significantly between weeks 3-5, suggesting potential for further research on these cells as a personalized treatment for Alzheimer's disease.

Yes-associated protein (YAP), the key transcriptional co-factor and downstream effector of the Hippo pathway, has emerged as one of the primary regulators of neural as well as glial cells. It has been detected in various glial cell types, including Schwann cells and olfactory ensheathing cells in the peripheral nervous system, as well as radial glial cells, ependymal cells, Bergmann glia, retinal Müller cells, astrocytes, oligodendrocytes, and microglia in the central nervous system. With the development of neuroscience, understanding the functions of YAP in the physiological or pathological processes of glia is advancing.

Neuroinflammation is a symptom of different neurodegenerative diseases, and growing interest is directed towards active drug development for the reduction of its negative effects. The anti-inflammatory activity of polyunsaturated fatty acids, eicosapentaenoic (EPA), docosahexaenoic (DHA), and their amide derivatives was largely investigated on some neural cells. Herein, we aimed to elucidate the protective role of both EPA and DHA and the corresponding -ethanolamides EPA-EA and DHA-EA on neonatal mouse Olfactory Ensheathing Cells (OECs) after exposition to lipopolysaccharide (LPS)-induced neuroinflammation.

Glia are imperative in nearly every function of the nervous system, including neurotransmission, neuronal repair, development, immunity, and myelination. Recently, the reparative roles of glia in the central and peripheral nervous systems have been elucidated, suggesting a tremendous potential for these cells as novel treatments to central nervous system disorders. Glial cells often behave as 'double-edged swords' in neuroinflammation, ultimately deciding the life or death of resident cells.
