This paper presents in vitro microvascular network formation within 3D gel scaffolds made from different concentrations of type-I collagen, fibrin, or a mixture of collagen and fibrin, using a simple microfluidic platform. Initially, microvascular network formation of human umbilical vein endothelial cells was examined using live time-lapse confocal(More)
Vagus nerve comprises two distinct kinds of nerves, nodose and jugular ganglionic nerves. We tested pharmacological difference between two vagal nerves in the responsiveness to FMRFamide. The response probability to FMRFamide was significantly higher in nodose than jugular nerves in intracellular calcium measurement. Nodose nerves also depolarized membrane(More)
The recombinant a and bsubunits for human coagulation factor XIII were transfected into Chinese hamster ovary (CHO) cells. CHO cells were amplified and selected with methotrexate in adherent cultures containing serum, and CHO 1-62 cells were later selected in protein-free medium. To develop a recombinant factor XIII production process in a suspension(More)
