Purpose: To investigate the embryotrophic mechanisms of Vero and oviductal cells coculture. Methods: Mouse embryos were cultured in Chatot, Ziomek, and Bavister medium (CZB), in modified CZB media (MM) with nutrient concentrations adjusted to that found in conditioned media after different periods of Vero cells or oviductal cells culture, in reconstituted(More)
Forced-expression of transcription factors can reprogram somatic cells into induced pluripotent stem cells (iPSC). Recent studies show that the reprogramming efficiency can be improved by inclusion of small molecules that regulate chromatin modifying enzymes. We report here that sirtuin 1 (SIRT1), a member of the sirtuin family of NAD(+)-dependent protein(More)
OBJECTIVE To determine the fertility and abortion rates in a mouse model of autoimmune thyroiditis and its relationship with circulating anti-thyroid peroxidase (TPO) antibody. DESIGN Experimental animal study. SETTING University research laboratory. ANIMAL(S) C57bl/6 mice. INTERVENTION(S) Female C57bl/6 mice immunized with recombinant mouse TPO(More)
Human embryonic stem cells (hESCs) have great potential for regenerative medicine as they have self-regenerative and pluripotent properties. Feeder cells or their conditioned medium are required for the maintenance of hESC in the undifferentiated state. Feeder cells have been postulated to produce growth factors and extracellular molecules for maintaining(More)
Exposure to maternal diabetes during fetal growth is a risk factor for the development of type II diabetes (T2D) in later life. Discovery of the mechanisms involved in this association should provide valuable background for therapeutic treatments. Early embryogenesis involves epigenetic changes including histone modifications. The bivalent histone(More)
