逆轉白髮流動力 重啟黑素幹細胞

研究發現,頭髮變白是因黑色素幹細胞受困於毛囊特定區域,無法移動並轉化為色素細胞。若能恢復幹細胞的流動性,使其重新獲得生成色素的能力,未來或可研發出逆轉白髮或預防褪色的治療方法。
頭髮變白是人類衰老的明顯特徵,其核心機制在於毛囊中黑素細胞幹細胞(Melanocyte Stem Cells, McSCs)的衰竭與功能障礙。最新的科學研究揭示了兩個導致頭髮變白的主要路徑:
1. 老化引起的「卡住」現象:正常情況下,McSCs具備在毛囊不同部位移動並在幹細胞狀態與成熟狀態之間切換的「變色龍」特徵。隨著年齡增長,越來越多的McSCs會卡在毛囊隆起部(Bulge),無法移動回毛髮胚芽(Hair Germ)接受成熟信號,導致色素再生失效。
2. 壓力誘導的永久耗竭:急性壓力會過度激活交感神經系統,釋放去甲腎上腺素(Norepinephrine),驅使原本處於靜止期的McSCs異常增殖、分化並遷徙出原位,最終導致幹細胞庫永久性耗竭。
此外,新興的再生醫療研究(如外泌體療法)顯示出逆轉或減緩頭髮變白的潛力。本文件旨在深入分析McSCs的細胞動力學、壓力對幹細胞的影響,以及目前的治療研究進展。
