To study the expression, purification and bioactivity of human augmenter of liver regeneration in Pichia Pastoris, the expression plasmid pPICZαA- ALR was constructed and transformed into P. Pastoris by the method of electroporation transformation. Induced with 0.5% methanol, the 30 kD protein in the culture supernatant of recombinant P. Pastoris was confirmed to be rhALR by SDS-PAGE and Western blot. Quantitative analysis showed that the target protein was in a level of 66% of the total protein of the culture supernatant, with a yield of 40mg/L.we had performed DEAE anion exchange chromatography two times with excessive and regular adsorption quantity consecutively, and then the rhALR above 95% purity and 52% protein recovery could be obtained by G75 molecular sieve chromatography at last step. The bioactivity assay of the purified product showed that rhALR could stimulate the proliferation of HepG2, SMMC-7721 and NIH-3T3 in vitro.

为在毕赤酵母中分泌表达人肝再生增强因子，以色谱法分离纯化后进行体外活性研究，构建表达载体pPICZαA- ALR，经电穿孔转入毕赤酵母中，用0.5％甲醇诱导表达；重组酵母培养上清经SDS-PAGE电泳和western blot鉴定后表明， rhALR以分子量为30kD的二聚体为主；定量分析结果表明，重组酵母培养上清中rhALR约占总蛋白的66％，表达量约为40mg/L；经DEAE柱和G75柱纯化后，获得的rhALR纯度大于95％，得率为52％；体外生物学活性实验表明，rhALR能明显促进HepG2、SMMC-7721和NIH-3T3细胞的增殖。

Investigation of formation, proliferation and degradation of the peroxisome is an important part of study of organelles biogenesis.

过氧化物酶体（peroxisome，P）是真核细胞中普遍存在的细胞器，参与多种重要的代谢过程。P的产生、增殖及降解是细胞器发生机理研究的重要部分。

Through a study on tissue cultureof the bud scale of corm of Lili longiflorum separated from the plant ,several practical TC prompt proliferation techniques ,such as inducing of lush bud ,proliferation cultivation of successive generation, cultivation of growing roots and transplanting , etc., are researched in this paper .

Consistent with predominantly stochastic gene expression and increased energy demands induced by aneuploidy,the "buffering" canalization processes in Down syndrome would be reduced thereby giving rise to increased variance to less stable developmental pathways such as proliferation.

与非整倍体诱导的主要预测基因的表达和增长的能量需要相一致，Down综合征中的"缓冲"的发育稳态过程将会减少，从而导致像增殖这样不稳定的发育途径的多样性增加。

It turned out that hematopoietic stem cells be immortalized by constitutive Notch1 and Delta has the function as the mitogenic regulators of hematopoietic stem cells.

研究人员将活化形式Notch受体导入造血干细胞，使其获得了细胞因子依赖性的"永生"；另外，Notch的配体Delta、Jagged具有类有丝分裂因子作用，可保持造血干细胞的自我更新能力，促进其体外增殖。

These culture conditions not only maintain the undifferentiated state and normal diploid karyotypes of BALB/c mouse ES cells effectively, but also maintain a series of their characteristics of murine stem cells. two different kinds of digestive methods and Two kinds of digestive juice with different concentrations were designed to dissociate proliferous inner cell mass and ES cell clonies deriver from dissociative ICM.
