CD34（小鼠、大鼠的同源蛋白写作Cd34），是一类分化簇（Cluster of differentiation, CD）分子，在人体内由CD34基因编码，主要用来鉴定造血干细胞（HSC）等成体干细胞[5][6][7]。CD34化学本质为糖蛋白，正常情况下位于细胞膜表面，功能包括参与细胞—细胞间黏附和细胞—细胞外基质（ECM）黏附。

功能

CD34最早于20世纪80年代由两个课题组同时独立发现，最初是用来鉴定一类造血干细胞（CD34+阳性）。现在，是否表达CD34也是分离、鉴别造血干细胞及其亚群（subpopulation）的一项重要指标[8][9][10][11][12][13]。CD34为单跨膜的黏液素（Mucin）类糖蛋白，通常分布于细胞膜表面[14]。CD34功能复杂，至今CD34的功能仍然未完全阐明，已知的CD34分子功能主要是参与细胞黏附[15][16]。

分布

CD34蛋白主要表达于造血干细胞和造血祖细胞中，同时，血管内皮细胞、一部分间充质干细胞（MSC）也表达CD34[17]。CD34在脐带和骨髓中表达强度相对较高[18]。
