DDF DFD 鼻嗅幹細胞之臨床級分離培養製程開發
以跨業合作的方式,共同設計開發具備臨床應用可能的間質幹細胞藥物,以確保未來臨床端運用之安全性及有效性。


人體內鼻腔嗅粘膜的固有層 (Lamina Propria) 附近,存在鼻嗅幹細胞 (Olfactory Ensheathing Cell, OEC),這些細胞具備骨髓間質幹細胞 (Mesenchymal Stem Cell, MSC) 的幹細胞特性 (Stemness)。

科學家已將這類細胞成功誘導成神經細胞,並在罹患帕金森氏症的小鼠上進行細胞移植,結果發現能改善小鼠的運動行為。期許未來能夠將鼻嗅幹細胞應用於腦部神經的修復,改善腦中風病患的神經功能喪失並提高其生活品質!



自鼻腔內中鼻甲取一小塊組織,經由酵素處理後,於特定培養基中貼附生長,經過一個月內的培養,OEC細胞快速增生至數億顆細胞。
擴增後的OEC細胞具備間質幹細胞 (MSC) 抗原表現,其中CD73、CD90、CD105皆高達95%;另外CD14、CD34、CD45皆低於2%。此外,第三代與第十代皆可保持同樣的抗原表現水平。
經由誘導培養基 (Induction) 定向分化測試,相較於脂肪間質幹細胞 (ADSC),OEC細胞分化成脂肪細胞的能力較弱,而軟骨和硬骨的分化則較佳。
這些實驗結果顯示,泰美緹康生醫成功自鼻嗅組織分離和大量培養得到OEC細胞,並建立相關的檢驗方法。

Development of Clinical-Grade Isolation and Culture Process for Olfactory Stem Cells

With cross-industry cooperation, TOP MEDICAL will design cellular drugs of mesenchymal stem cell for clinical applications to ensure the safety and effectiveness in the future.


鼻腔內視鏡照

We identified multipotent stem cells, called olfactory ensheathing cells (OECs) within the lamina propria of the human olfactory mucosa, located in the nasal cavity, these cells have specific stemness that closely related to bone marrow mesenchymal stem cell (BM-MSC).

這些實驗結果顯示,泰美緹康生醫成功自鼻嗅組織分離和大量培養得到OEC細胞●Collect nasal biopsies from middle turbinate of nasal cavity, tissue with specific treatment, then culture in specific medium, OECs will proliferate rapidly into billions of cells in one month.

●After proliferation, OECs demonstrated the expected phenotype for MSCs, positive expression of CD73, CD90, CD105 (≥ 95%), negative expression of CD14, CD34, CD45 (≤ 2%). In passage 3 and passage 10, the phenotype maintains the same level.

●Compared to the adipose derived stem cells (ADSCs), OECs was judged to own osteogenic and chondrocytic differentiation capabilities, but weak adipogenic differentiation capability.

●These results showed that TOP MEDICAL can successfully isolate and proliferate OECs. We proposed a series of testing method to prove OECs have the similar characteristics with MSCs.
