BACKGROUND AIMS Mesenchymal stromal cell (MSC) transplantation holds great promise for use in medical therapies. Several key features of MSCs, including efficient cell growth, generation of sufficient cell numbers and safety, as determined by teratoma formation, make MSCs an ideal candidate for clinical use. However, MSCs derived under standard culture(More)
Human amniotic fluid stem (hAFS) cells have become an attractive stem cell source for medical therapy due to both their ability to propagate as stem cells and the lack of ethical debate that comes with the use of embryonic stem cells. Although techniques to derive stem cells from amniotic fluid are available, the techniques have limitations for clinical(More)
Amniotic fluid stem cells (AFSs) are interesting mesenchymal stem cells (MSCs) that are characterized by their great potential for cell proliferation and differentiation compared with other types of MSCs identified to date. However, MSCs in prolonged culture have been found to exhibit defects in genetic stability and differentiation capacity. Epigenetic(More)
It has been recognized that multiple pregnancy is associated with the increase risks to both maternal and newborn compared to singleton pregnancy. High incidence of premature birth complicated in the multiple pregnancy not only result in the high neonatal morbidity and mortality rate but also consume a high financial cost for the intensive neonatal care and(More)
BACKGROUND AIMS Human amniotic mesenchymal stromal cells (hAMSCs) are a potent and attractive stem cell source for use in regenerative medicine. However, the safe uses of therapeutic-grade MSCs are equally as important as the efficiency of MSCs. To provide efficient, clinic-compliant (safe for therapeutic use) MSCs, hAMSC lines that completely eliminate the(More)
Neurodegenerative disorders are characterized by chronic and progressive loss of neurons in structure and function related to aging, such as Alzheimer's disease, the latter characterized by the degeneration of cholinergic neurons in basal forebrain connected to the cerebral cortex and hippocampus. Amniotic fluid mesenchymal stem cells (AF-MSCs) have been(More)
Mesenchymal stem cells (MSC) are promising cells for medical therapy. In in vitro expansion, MSC can give rise to progeny with genomic and epigenomic alterations, resulting in senescence, loss of terminal differentiation, and transformation to cancer. However, MSC genome protects its genetic instability by a guardian function of the P53 tumor suppressor(More)
A prospective experimental study was performed to compare sperm cryosurvival rate between two kinds of cyroprotective media: citrate-egg yolk-glycerol (CEG) and TEST-citrate-egg yolk-glycerol (TEST-EYG), and between two freezing methods: noncontrolled rate (NCR) freezing and computer controlled rate (CR) freezing. One hundred semen samples were included in(More)
Transplantation of mesenchymal stem cells (MSC) can effectively repair endometrial deficiencies, including infertile patients with a problem of inadequate endometrium thickness. Although, MSC derived from different organ sources have a similarity of MSC specific characteristics, endometrial stem cells (EMSC) are temporally regulated throughout the menstrual(More)
