摘要:
An oxygen sensing element capable of measuring partial pressures of oxygen in sample gases, which element has a solid electrolyte member having totally embedded therein a means for providing a reference partial pressure of oxygen composed of a sintered product of a finely divided metal or metal-metal oxide mixture and having a lead-out wire connected thereto is prepared by a method wherein: p1 (a) a part of the finely divided solid electrolyte material is compression-molded to form a provisional solid electrolyte member having a hole;(b) a provisional product of the reference oxygen partial pressure-providing means is formed in the hole of the provisional solid electrolyte member from the finely divided metal or metal-metal oxide mixture;(c) the remaining part of the finely divided solid electrolyte material is piled up on the provisional reference oxygen partial pressure-providing means product, followed by compression molding the piled up solid electrolyte material to form an integrated structure comprising the solid electrolyte member having totally embedded therein the provisional reference oxygen partial pressure-providing means;(d) the integrated structure is sintered in a non-oxidizing atmosphere at approximately 1,350.degree. to 1,500.degree. C.; and,(e) a layer or layers of an external conductive metal electrode or electrodes is formed on at least a part of the exterior surface of the sintered product.

The introduction of the human NeuroD1 gene into human non-endocrine pancreatic epithelial cells (NEPECs) for producing insulin producing cells in vitro is described herein. Cytokeratin19 (CK19) positive NEPECs were transfected with plasmids encoding human NeuroD1 gene under human CK19 promoter. On characterization following the induction it was found that NEPEC+ND strongly expressed NeuroD1 and insulin mRNA. The ratio of NeuroD1 and human insulin positive cells in NEPEC+ND was significantly higher than NEPEC. Human insulin and C-peptide levels in culture media in NEPEC+ND were significantly higher than NEPEC. The findings demonstrate that human NeuroD1 under control of the CK19 promoter induces the differentiation of CK19 positive NEPECs into insulin producing cells.
