The effect of conditioned media obtained from different smooth muscle cells (SMC) on tissue factor (TF) expression in endothelial cells (EC) in vitro was investigated. We could show that conditioned media from cultured human aortic SMC, human umbilical artery SMC or human umbilical vein SMC all resembling the synthetic phenotype of SMC induced TF activity in human umbilical vein EC and human sk...

Congenital umbilical cord hernia is fairly common in infants and it is rarely associated with other anomalies. Sometimes, large umbilical cord hernia is confused with Small omphaloceles. We report an unusual case of umbilical cord hernia associated with patent vitello-intestinal duct (PVID), and Meckel's diverticulum underwent surgery and discharged with good general condition.

BACKGROUND Umbilical cord banks are a central component, as umbilical cord tissue providers, in both medical treatment and scientific research with stem cells. But, whereas the creation of umbilical cord banks is seen as successful practice, it is perceived as a risky style of play by others. This article examines and discusses the ethical, medical and legal considerations that arise from the o...

Endothelial cells were isolated from freshly obtained human umbilical cords by collagenase digestion of the interior of the umbilical vein. The cells were grown in tissue culture as a homogeneous population for periods up to 5 mo and some lines were subcultured for 10 serial passages. During the logarithmic phase of cell growth, cell-doubling time was 92 h. Light, phase contrast, and scanning e...
