台灣外泌體登國際期刊!生髮功效人體實證97%有感

國防醫學大學謝儒生博士團隊開發Bio-Pulsed生化脈衝外泌體技術,經人體功效測試證實生髮效果,60天後97%受試者髮根健康改善,研究成果登上國際期刊,展現台灣外泌體技術實力。

掉髮、髮量稀疏、髮際線後退,幾乎是每個成年人心中的痛,市面上生髮產品百百款,但真正經過「人體」驗證的技術卻少之又少。這次由國防醫學大學兼任教授謝儒生博士所帶領的研發團隊,開發出Bio-Pulsed(生化脈衝)外泌體技術,不僅完成人體功效測試,更成功登上國際期刊,證明台灣的外泌體技術實力,已經站上國際舞台,這也是許多關注生技與再生醫學讀者最期待看到的突破。

掉髮困擾人人有,關鍵技術終於突破

掉髮、髮量減少、髮際線逐漸後退,是許多成年人共同面臨的困擾。近年來,幹細胞、外泌體與各式再生技術紛紛投入生髮研究領域,但許多研究成果仍然停留在細胞實驗或動物實驗階段,能否真正跨越實驗室的門檻、進一步在人體上驗證功效,一直是研究成果能否走向實際應用的關鍵挑戰。而這次由謝儒生博士團隊開發的生化脈衝外泌體育髮技術,已經正式達到這項重要里程碑,成為少數完成人體驗證的外泌體生髮技術。

國際期刊認證,研究成果有憑有據

該研發團隊開發出的Bio-Pulsed(生化脈衝)外泌體,研究歷程從關鍵miRNA、毛囊細胞活性,一路追蹤驗證至人體功效,研究成果已陸續刊登在2022年國際期刊《International Journal of Molecular Sciences》,以及2025年國際期刊《Current Issues in Molecular Biology》上,等於是經過國際學術界的雙重把關與認可。研究結果顯示,僅使用30天,30名受試者就全數呈現毛囊活化指標提升;持續使用60天後,更有97%受試者呈現髮根健康改善、97%呈現毛髮密度改善、93%呈現頭皮活化改善,數字相當亮眼,也讓人對台灣生技研發實力刮目相看。

毛囊週期是關鍵,60天實測全解密

事實上,頭髮能否持續生長,關鍵就在於毛囊週期。正常毛囊會在生長期(Anagen)、退化期與休止期(Telogen)之間不斷循環;一旦生長期縮短、越來越多毛囊進入休止狀態,毛髮便可能逐漸變細、脫落,最終形成肉眼可見的髮量稀疏現象。此次研究共納入30名年齡介於30至65歲、具有輕至中度毛髮稀疏情形的男女受試者,進行為期60天的生化脈衝外泌體局部使用研究,並分別於第0天、第30天及第60天,進行客觀儀器分析比對,確保數據的科學嚴謹度。

研究結果相當令人振奮,在使用30天後就能觀察到顯著改善效果;而在60天後,代表毛囊活躍程度的生長期/休止期毛髮比值(A/T ratio),全數受試者皆有所提升,整體平均更是大幅提升48.7%,掉髮量平均減少46.5%,毛髮密度則提升7.6%,前後數據比較皆達到統計上的顯著差異。這也代表毛囊的活化、掉髮的減少、毛髮密度的增加,都是可以被量化、被驗證的實質改變,而研究團隊看到的不只是「頭髮看起來變多」的表象,而是真正讓毛囊重新回到生長期的本質改變。

外泌體是什麼?生物訊息包大解密

究竟外泌體是什麼?其實外泌體就像是細胞送出的「生物訊息包」,其中攜帶著蛋白質、脂質與miRNA等分子,負責將重要訊息傳遞給其他細胞,扮演細胞之間溝通的重要媒介。因此,真正影響外泌體功能好壞的,不只是「顆粒數量有多少」,更重要的關鍵在於,這些外泌體裡面究竟帶著什麼樣的訊息內容,這也是這次研究團隊技術突破的核心所在。

AI加持基因定序,精準調控見真章

謝儒生教授所帶領的研發團隊,透過AI人工智慧和次世代基因定序(NGS)技術,結合Bio-Pulsed(生化脈衝)技術平台,精準篩選並調控幹細胞培養過程中的各項變因,最終研發出相較於一般外泌體,最高高出約68倍之毛囊調控相關功能性miRNA的生化脈衝外泌體,其中包括miR-21-5p、miR-181a-5p、miR-125b-5p、miR-199a-5p、miR-27b-3p及miR-34a-5p等多種關鍵分子,並進一步透過細胞實驗和人體功效測試來完整驗證其作用機制。研究團隊發現,其中miR-181a-5p能夠啟動Wnt/β-catenin訊號路徑,藉此刺激毛囊幹細胞、促進毛髮生長;而miR-22-3p則具備對抗雄性禿與促進毛髮生長的潛力,兩者相輔相成,為生髮技術帶來全新解方。

研發思維大不同,台灣技術站上國際舞台

不同於過去「先取得外泌體、再尋找可能用途」的傳統開發思維,這次研發團隊選擇從目標功能出發,透過調控細胞微環境與生化刺激的方式,引導細胞產生具有特定功能性訊息的外泌體。研究團隊關注的重點,不只是外泌體的來源與顆粒數量,而是進一步追問:這些外泌體究竟帶著什麼樣的訊息、如何在體內發揮作用,以及最終能否真正在人體上被驗證,這樣的思維轉變,也讓研究成果更具實用價值與說服力。

從實驗室裡的一段miRNA分子,到人體上一根根毛髮的實際變化,Bio-Pulsed(生化脈衝)技術讓外泌體從原本充滿潛力卻缺乏驗證的話題性原料,逐步走向功能可以被設計、機制可以被解析、人體功效可以被驗證的完整技術平台。這項由台灣研發團隊一手推進的研究成果,也讓國際看見台灣在下一代外泌體技術上的研發實力與轉譯能量,為台灣生技產業寫下亮眼的一頁。
