Effects of Visible Light on the Development of Mouse 2-Cell Embryos
Introduction: Mammalian embryos as well as oocytes are prone to various doses of visible light during manipulations in laboratory. The present study was designed to investigate the effects of visible light on the development of mouse 2- cell embryos. Method: Non-pregnant female NMRI mice were super-ovulated with i.p. injection of 7.5 iu PMSG followed 48 hours later with 10 iu hCG. Forty eight h...
متن کاملP-30: Developmental Capacity and Blastocyst Formation of Thawed Tetrahedral Versus Non-Tetrahedral 4-cell Stage Mouse Embryos After Vitrification
Background: It was reported in a literature that approximately one third of the 4-cell stage embryos did not exhibit a tetrahedral shape. Non-tetrahedral embryos showed a lower in vitro developmental potential than tetrahedral embryos. Recently vitrification technology has been widely employed for embryo cryopreservation. The objective of this study was to prove our hypothesis that vitrified - ...
متن کاملP-60: Survival Assessment of Mouse In Vitro Embryos after Exposure to Cell Phone Radiation
Background Using cellular phone among adults, teenagers and children has rapidly increased all over the world. Also, the concern on the possible health hazards of Electromagnetic Fields (EMF) induced from cell phones on reproduction has been growing in many countries. The aim was to assess the morphological parameters, survival rate and development of mouse in-vitro embryos obtained by natural ...
متن کاملMorphogenetic analysis of changing cell associations following release of 2-cell and 4-cell mouse embryos from cleavage arrest.
Two-cell and four-cell mouse embryos were cultured in Cytochalasin D (CD) for 40-48 h. They were fixed for light and electron microscopy at various times after washing off the CD. Cleavage-arrested embryos in CD had well separated blastomeres but by 1 h from washing the embryos had compacted, in most cases without undergoing cell division. By 2 h after release from arrest one blastomere of the ...
متن کاملSirt3 protects in vitro-fertilized mouse preimplantation embryos against oxidative stress-induced p53-mediated developmental arrest.
Sirtuins are a phylogenetically conserved NAD+-dependent protein deacetylase/ADP-ribosyltransferase family implicated in diverse biological processes. Several family members localize to mitochondria, the function of which is thought to determine the developmental potential of preimplantation embryos. We have therefore characterized the role of sirtuins in mouse preimplantation development under...
