Abstract: The present invention relates to an induced pluripotent stem cell (iPS) model for cardiofaciocutaneous (CFC) syndrome, a method for producing the model, and uses of the iPS model in the analysis of neural development in CFC syndrome. Specifically, the CFC syndrome-derived iPS and generation and differentiation of an embryonic body were induced from the fibroblasts of a CFC syndrome patient, and the CFC syndrome-derived iPS and embryonic body were confirmed to exhibit broken embryonic body shapes and no differentiation into neurons. When a CFC syndrome-derived embryonic body was induced by treating with p-ERK and p-SMAD1 inhibitors, the embryonic body exhibited a normal embryonic body shape and effectively differentiated into neurons. Thus, the CFC syndrome patient-derived stem cell model of the invention can be effectively used in the research for neural development in cardiofaciocutaneous syndrome.

Abstract: Provided is a method for separating a nanogenerator, which includes laminating a buffer layer on a sacrificial substrate, making a nanogenerator on the buffer layer, laminating a metal layer on the nanogenerator and separating the nanogenerator from the buffer layer. Here, a nanogenerator is separated by using a stress difference between the sacrificial substrate and the metal layer, instead of an existing method in which a nanogenerator is separated from the sacrificial substrate by means of wet etching or the like. In particular, according to a difference between a tensile stress at the metal layer such as nickel and a compressive stress at the lower silicon substrate, the nanogenerator is intactly separated from the silicon oxide layer serving as a buffer layer. Therefore, the nanogenerator may be separated from the sacrificial substrate in a mechanical way, which is safer and more economic in comparison to an existing chemical separation method using an etching solution.
