OBJECTIVE Uterine transplantation experiments have been performed in various animal species for future clinical applications of uterine transplantation for permanent uterine factor infertility in humans. The aim of this study was to confirm the feasibility of uterine auto-transplantation in cynomolgus monkeys by developing new surgical techniques. METHODS(More)
Enzymes used for passaging human pluripotent stem cells (hPSCs) digest cell surface proteins, resulting in cell damage. Moreover, cell dissociation using divalent cation-free solutions causes apoptosis. Here we report that Mg(2+) and Ca(2+) control cell-fibronectin and cell-cell binding of hPSCs, respectively, under feeder- and serum-free culture conditions(More)
In this study, we investigated whether glucagon-like peptide-2 (GLP-2) had antidepressant-like effects in mice, and whether these activities were associated with monoamine systems in mice. Antidepressant-like effects were evaluated based on the immobility time in the forced-swim test. GLP-2 (1.5-6 microg/mouse, i.c.v.) significantly reduced the immobility(More)
Because mouse embryonic stem cells (mESCs) do not contribute to the formation of extraembryonic placenta when they are injected into blastocysts, it is believed that mESCs do not differentiate into trophoblast whereas human embryonic stem cells (hESCs) can express trophoblast markers when exposed to bone morphogenetic protein 4 (BMP4) in vitro. To test(More)
BACKGROUND The successful establishment of human induced pluripotent stem cells (hiPSCs) has increased the possible applications of stem cell research in biology and medicine. In particular, hiPSCs are a promising source of cells for regenerative medicine and pharmacology. However, one of the major obstacles to such uses for hiPSCs is the risk of(More)
The neural crest (NC) is a group of cells located in the neural folds at the boundary between the neural and epidermal ectoderm. NC cells differentiate into a vast range of cells,including neural cells, smooth muscle cells, bone and cartilage cells of the maxillofacial region, and odontoblasts. The molecular mechanisms underlying NC induction during early(More)
INTRODUCTION To date, an electron microscopy study of the collecting lymphatic vessels has not been conducted to examine the early stages of lymphedema. However, such histological studies could be useful for elucidating the mechanism of lymphedema onset. The aim of this study was to clarify the changes occurring in collecting lymphatic vessels after(More)
P-glycoprotein (P-gp) is one of the ATP-binding cassette transporters and acts as an efflux pump for cytotoxic substances. P-gp mRNA expression and transporting activity show the daily rhythm and contribute to the chrono-pharmacokinetic profiles of many drugs. It is reported that the daily rhythm of abcb1a mRNA is regulated by a circadian clock-controlled(More)
A rapid increase in research on the relationship between histone modifications and their subsequent reactions in the nucleus has revealed that the histone modification system is complex, and robust against point mutations. The prevailing theoretical framework (the histone code hypothesis) is inadequate to explain either the complexity or robustness, making(More)
PC12 cells, a widely used model neuronal cell line, are usually cultured in serum-supplemented medium. This report describes a serum-free medium for the culture of PC12 cells. PC12 cells grown in the two media types had similar growth rates and released dopamine in response to high potassium-induced calcium elevation. However, the levels of dopamine and of(More)
