Research ArticleOpen accessIn the abstractGene Technology in Tissue EngineeringXiao-Dan Sun, In-Seop LeeScaffold, cells and signaling factors are regarded as the three essential components in tissue engineering. With the development of molecular and cell biology, gene technology is beginning to show a promising position in tissue engineering as it can influence these essential components at DNA-level. By introducing plasmid DNA or genes encoding certain signaling factors (growth factors/cytokines) into the cells, required … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 6,401 accessesView PDFCite
Research ArticleOpen accessIn the abstractPDX-1 and MafA: Key Transcription Factors in PancreasHideaki Kaneto, Takeshi Miyatsuka, Yoshihisa Nakatani, Taka-aki MatsuokaPancreatic and duodenal homeobox factor-1 (PDX-1) plays a crucial role in pancreas development, β-cell differentiation and in maintaining normal β-cell function by regulating several β-cell-related genes including insulin. PDX-1 has potency to induce insulin-producing cells in non β-cells in various tissues such as pancreas and liver and PDX-1-VP16 fusion protein more efficiently induces insulin-producing cells, especially in the presence of … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 7,389 accessesView PDFCite
Research ArticleOpen accessIn the abstractFourier Series With Spectral and Wave Number DecompositionJung-Hua Chou, Raylin WuIn this study, the generic nature of Fourier series is pointed out and the requirement of dimensional homogeneity for physical systems is emphasized. By suitable application of non-dimensional variables, both time versus frequency and spatial versus wave number decomposition of Fourier series are included properly to put the physics involved into the right physical meanings. Furthermore, the high frequency noise … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,249 accessesView PDFCite
