Human stem cells and progenitor cells can be used to treat cancer and replace dysfunctional cells within a tissue or organ. The objective of this study was to identify the appropriate cells type in regenerative medicine and targeted therapy. As an alternative to embryonic and bone marrow stem cells, we examined human amniotic fluid stem cells (hAFSCs), one of the potential source of multipotent...
We report the presence of truncated forms of the nerve growth factor receptor (NGFRt) in the conditioned medium of the human melanoma cell line A875 and in human urine and amniotic fluid. Radioiodinated nerve growth factor (125I-NGF) specifically bound to NGFRt was chemically cross-linked. After immunoprecipitation, labeled receptor species were visualized by autoradiography following sodium do...
The fetal intestinal mucosa is characterized by elevated Toll-like receptor 4 (TLR4) expression, which can lead to the development of necrotizing enterocolitis (NEC)--a devastating inflammatory disease of the premature intestine--upon exposure to microbes. To define endogenous strategies that could reduce TLR4 signaling, we hypothesized that amniotic fluid can inhibit TLR4 signaling within the ...
Deviations from the normal of alpha-fetoprotein (AFP) concentrations in fetal serum, amniotic fluid, maternal serum and adult human serum can be explained by understanding the normal physiology and the pathophysiology of AFP synthesis and metabolism. AFP is the prototype of oncofetal markers. Emphasis is given to the usefulness of elevated serum AFP levels on the diagnosis and management of pri...
Intramembranous absorption increases during intra-amniotic infusion of physiological saline solutions. The increase may be due partly to the concomitant elevation in fetal urine production as fetal urine contains a stimulator of intramembranous absorption. In this study, we hypothesized that the increase in intramembranous absorption during intra-amniotic infusion is due, in part, to dilution o...
The presence of contaminating maternal cells in amniotic fluid is an important, though infrequent, cause of error in karyotyping the fetus. A method of detecting contaminating maternal cells in amniocentesis specimens by determining the HLA phenotype of the cells of amniotic fluid and the mother is described. Tissue typing of 15 amniocentesis specimens was performed, and in 14 cases the fetal o...
OBJECTIVE This study aims to treat patients with preterm premature rupture of the membranes (PPROM) and anhydramnion using continuous amnioinfusion through a subcutaneously implanted port system. METHODS An amniotic fluid replacement port system was implanted in seven patients with PPROM and anhydramnion starting at the 20th week of gestation (range, 14-26 weeks) for long-term amnioinfusion. ...
We developed a new method for an objective assessment of the meconium content in amniotic fluid. By establishing a standard scale through a serial dilution of a known amount of meconium into the amniotic fluid, we developed a new method "mecometer" that can objectively measure the meconium content in meconium-stained amniotic fluid samples. The objectivity and reliability of this mecometer were...
