Results show that the morphology of HNS changes from short plane-like shape to long plane-like shape when non-solvent temperature changes from 25℃ to 50℃. The morphology comes through the variety of ellipsoid, short plane-like and club-shaped with pH value of non-solvent from acidity to neutral and finally basical, with the particle size distribution in 50-300 nm, 50-500 nm, and 50-600 nm, respectively. Ellipse plane-like and long club-shaped morphology HNS were obtained using white dextrine and sodium carboxymethyl cellulose as surfactants in non-solvent, with the particle size distribution in 50-300 nm and 50-600 nm.

结果表明：非溶剂温度由25℃升高到55℃后，HNS晶体形貌由短片状变为细长片状；pH值由酸性变化到中性再到碱性时，亚微米HNS的晶体形貌经历椭球状、短片状、棒状的系列变化，粒度分布分别处于50~300 nm、50~500 nm、50~600 nm；白糊精和羧甲基纤维素钠作为晶形控制剂修饰后的亚微米HNS晶体形貌分别椭圆片状和长棒状，粒度分布分别处于50~300 nm、50~600 nm。

Methods: The CD34+ cells and AC133+ cells were gathered by MiniMACS, then the cell factors were divided into 6 groups. Through the ex vivo comparison cultivation under different cell factor combination stimulation, expansion of the CD34+ and AC133+ selection cells was observed and the clone formation of the CD34+ and AC133+ cells was also observed by using Half-solid Methyl cellulose under different cell factor stimulation (in7d, 14d, 21d.). The rate of cell apoptosis was determined.

Methods CD34(superscript +) cells and AC133(superscript +) cells were gathered by MiniMACS, then the cell factors were divided into 6 groups. Through the ex vivo comparison cultivation under different cell factor combination stimulation, expansion of the CD34(superscript +) and AC133(superscript +) selection cells was observed and the clone formation of the CD34(superscript +) and AC133(superscript +) cells was also observed by using Half-solid Methyl cellulose under different cell factor stimulation (during 7d, 14d, 21d.). The rate of cell apoptosis was determined.
