Construction And Expression Identification Of Human Secreted Apoptosis-Related Protein 1 Gene Yeast Two-Hybrid Bait Vector, Wei Zhang, Guangzhao He, Bing Ma

Bing Ma

Objective: To construct human secreted apoptosis-related protein 1 (SARP1) gene yeast two-hybrid bait vector so as to study the biological functions of the SARP1 gene in the scar tissue. Methods: The target gene from SARP1 gene full-length DNA segment was amplified by PCR, the upstream and downstream primers of the SARP1 gene with restriction enzymes Nde I and Sal I were designed. pGBKT7-SARP1 recombination plasmid was constructed by ligating the vector and the PCR production and identified by PCR and sequencing. Furthermore, pGBKT7-SARP1 was transformed into competent AH109 which contained kanamycin for selecting positive clones and screened the positive clony …

A new and simple method for fabrication of nanofiber scaffolds with gradations in fiber organization is reported. The nanofiber organization, achieved by deposition of random fibers on the uniaxially-aligned nanofiber mat in a gradient manner, directed morphological changes of applied adipose-derived stem cells. These morphological changes and resultant biochemical changes can help mimic the structural orientation of complex biomechanical structures like the collagen fiber structure at the tendon-to-bone insertion site. In addition, chemical gradients can be established through nanoencapsulation in this novel scaffold allowing for enhanced biomedical applications.
