Abstract
以往研究人類臍帶的基質,是指「瓦頓氏凝膠(Wharton’s jelly, WJ)」,已經成功的由臍帶中分離出來,且可以成功的在體外培養數代,被發現此細胞具有間質性幹細胞的特性,也可以在體外成功的分化成脂肪細胞、軟骨細胞、骨細胞和類神經膠質細胞等。
  最近的研究指出,人類動脈脈血管管壁含有間質性幹細胞,也發現其具有往硬骨以及脂肪分化的潛力。目前和骨髓間質性幹細胞擠身為幹細胞研究發展的要角,而臍帶動脈的研究正在起步,期望在臍帶動脈所分離出來的細胞中,能夠有新的發現。
  分析臍帶動脈所分離出來的細胞,了解其細胞根本性質,並藉由給予DMEM含20% FBS條件培養基,促使細胞朝不同方向生長,所分離的人類臍帶動脈細胞,可以成功的在體外培養,且能成功的培養至第二十二代,仍有良好的增生能力;藉由流式細胞儀偵測的結果顯示CD29、CD44、CD49d、CD49e、CD49f、CD105、CD166、CDw90、SH2、SH4、HLA-ABC這些間質性細胞會表現的表面抗原在人類臍帶動脈皆為正向表現。而以EGM-2含10%FBS培養基培養的細胞略帶有造血系幹細胞的表面抗原(CD14、CD31),在培養第十六代後的增生能力趨漸減弱。
  再給予不同的分化條件,發現人類臍帶動脈所分離出來的細胞有能力往軟骨分化、硬骨分化、脂肪分化、神經細胞的分化,以上皆為間質性幹細胞的分化特性。綜合實驗結果,我們可以發現,人類臍帶動脈細胞,屬於間質性幹細胞的一種。
