CD34(小鼠、大鼠的同源蛋白寫作Cd34),是一類分化簇(Cluster of differentiation, CD)分子,在人體內由CD34基因編碼,主要用來鑑定造血幹細胞(HSC)等成體幹細胞[5][6][7]。CD34化學本質爲糖蛋白,正常情況下位於細胞膜表面,功能包括參與細胞—細胞間黏附和細胞—細胞外基質(ECM)黏附。
功能
[编辑]CD34最早於20世紀80年代由兩個課題組同時獨立發現,最初是用來鑑定一類造血幹細胞(CD34+陽性)。现在,是否表達CD34也是分離、鑑別造血幹細胞及其亚群(subpopulation)的一項重要指標[8][9][10][11][12][13]。CD34为单跨膜的黏液素(Mucin)類糖蛋白,通常分佈於細胞膜表面[14]。CD34功能複雜,至今CD34的功能仍然未完全闡明,已知的CD34分子功能主要是參與細胞黏附[15][16]。
分佈
[编辑]CD34蛋白主要表達於造血幹細胞和造血祖細胞中,同時,血管內皮細胞、一部分間充質幹細胞(MSC)也表達CD34[17]。CD34在臍帶和骨髓中表達強度相對較高[18]。
