生物谷報道：當心臟病發(fā)作或中風后,，醫(yī)師希望可以讓新血管快速地形成以加速傷口的愈合,。有一種實驗性藥物可以動員患者的血管新生細胞，幫助患者的血管快速生成,。
華盛頓大學醫(yī)學院的研究人員經(jīng)過多年研究證實了一種稱為AMD3100的藥物可以在幾小時而非幾天的時間內(nèi),，從骨髓動員患者的血管新生細胞，AMD3100的作用類似于G-CSF,。它的作用機理是作為CXCR4的抑制劑發(fā)揮作用的,。
血管新生細胞主要位于骨髓中，當動員時可以經(jīng)由血液循環(huán)來到受損的組織，并幫助修補和重新生長可將氧氣和營養(yǎng)物質(zhì)帶給受損組織的血管,。
G-CSF也可以將這些有利的細胞,，從骨髓帶入血液中，但是一直要等到第四天,，血管新生細胞才會進入血液中,。在二項G-SCF的臨床試驗中，都發(fā)現(xiàn)這種治療方式無法改進心臟病發(fā)作的心肌補救效果,。
在本篇發(fā)表于Blood的文章中,，研究人員表示，AMD3100可以在四個小時內(nèi),，就能讓血液中某些血管新生細胞的數(shù)量增加10到20倍,，因此，這將是治療心臟病發(fā)作或中風更有效的藥物,。
生物谷下面列出了有關(guān)該藥物的一系列研究論文,，感興趣的可以綜合閱讀。
