We demonstrated that recombinant baculovirus vectors expressing p35 (Ac-CMV-p35) and eGFP could be transduced into human kidney 293 cells efficiently. The level of transgene expression was viral dose dependent and high-level expression of the target gene could be achieved under the heterogonous promoter.

本研究证明重组杆状病毒载体Ac-CMV-p35和Ac-CMV-GFP能有效地转导人胚肾293细胞，并介导外源基因高效表达，目的基因的表达水平与杆状病毒的感染剂量成正线性相关。

This paper studies the exponential stability of cellular neural networks with time- varying delay by making use of the homoeomorphism theory, the idea of vector Lyapunov function, M- matrix theory and inequality - technique, offering the grounds for uniqueness of equilibrium point existence and the global exponential stability and estimating the exponential convergence rate index.

利用同胚映射理论、向量Lyapunov函数思想、M-矩阵理论和不等式技术，研究了具有变时滞的细胞神经网络模型的全局指数稳定性，给出了判定平衡点的存在唯一性以及全局指数稳定性的一个判据，并且估计了收敛速度指标。

Amplified cells were cultured in PGC culture medium and non-adherence culture flask till idiosome formed, adhered and differentiated.

The effects of GA 3 and IAA on fiber cell elongation were studied by in vitro cotton ovule culture and by comparison of a lintless mutant (Ligon cotton, Li 1) with its wild type (li 1) in upland cotton (Gossypium hirsutum L.).

棉纤维是由棉花胚珠外珠被表皮细胞分化与发育而来的单细胞，通常将纤维发生与发育分为起始、伸长、次生细胞壁合成和脱水成熟 4个阶段。

Bone marrow-derived mesenchymal stem cells are a population of cells capable of replicating as undifferentiated cells and that have the potential to differentiate to lineages of mesoblastic origin. And the characters of BMSCs have suggested the great value of this specific cell population for tissue engineering.

骨髓间充质干细胞具有自我复制、未分化的特点，并可在不同条件下分化为中胚层起源的多种细胞，这些特点决定了其在组织工程中的重要地位。

Adult mesenchymal stem cells are non-hematopoietic cells with multi-lineage potential to differentiate into various tissues of mesodermal origin.

成人间质干细胞是一种具有分多谱系化能力，能分化成中胚层来源的各种组织的非造血细胞。

In addition to this main pathway, howeer, ECs also can be generated from the EGFR-2–PDGFR-+ single-positie population, which represents the paraxial mesodermal lineage and is also deried from the DP population.

除这条主要途径外，内皮细胞也可从EGFR-2+PDGFR-+单阳性群体中得到，这种单阳性群体在近中胚层出现，并也来自于双阳性群。

From the study, we conclude that bFGF has the differentiative, migrative and mitogenic functions in the developing chick neuroretina.
