In the present method, first, a liquid culture medium containing the cardiac muscle cells is supplied onto a substrate comprising a first electrode, a second electrode and insulative fibers on the surface thereof. At least a part of the insulative fibers is located between the first electrode and the second electrode in a top view of the substrate. Then, the substrate is left at rest. Finally, the cardiac muscle cells are cultivated, while a pulse electric current is applied to the cardiac muscle cells through the first electrode and the second electrode.Type: GrantFiled: December 20, 2017Date of Patent: April 27, 2021Assignee: PANASONIC CORPORATIONInventors: Kiyotaka Tsuji, Li Liu

Patent number: 10982213Abstract: The present invention discloses an siRNA that inhibits K-RAS gene expression, and the precursor sequences and applications thereof. The K-RAS siRNA and its precursor sequences provided by the present invention can efficiently inhibit the expression of the K-RAS gene, and in vivo experiments have shown that the K-RAS siRNA has a certain inhibitory effect on tumours highly expressing K-RAS. The precursor of the siRNA of the invention and its vector can form a stable siRNA that functions in a host.Type: GrantFiled: May 5, 2017Date of Patent: April 20, 2021Assignee: JIANGSU MICROMEDMARK BIOTECH CO., LTD.Inventors: Chenyu Zhang, Xi Chen, Hongwei Liang, Uzair Ur-Rehman, Ke Zeng
