Microfabricated glass devices for rapid single cell immobilization in mouse zygote microinjection.
نویسندگان
چکیده
This paper presents the design and microfabrication of a vacuum-based cell holding device for single-cell immobilization and the use of the device in mouse zygote microinjection. The device contains many through-holes, constructed via two-sided glass wet etching and polydimethylsiloxane (PDMS)-glass bonding. Experimental results of mouse zygote immobilization and microinjection demonstrate that the device is effective for rapid cell immobilization and does not produce negative effect on embryonic development.

P-26: The Effect of Zygote and 2-cell Development Stages on Vitrification Process of Mouse Embryo
Background: While it is possible to routinely cryopreserve embryos from several mammalian species, the cryopreservation of embryos has largely been limited by their high sensitivity to chilling injury. Many factors such as the stage of embryonic development, cryoprotectant toxicity, the composition of the vitrification solution and cooling and warming rates can influence survival of embryos aft...

Background: Gaucher disease is an autosomal recessive inherited lysosomal storage disorder that affects many of the body's organs and tissues by defective function of the catabolic enzyme β-glucocerebrosidase. Gene therapy is one of the efficient ways for treatment of this disease. Due to the lack of appropriate animal models, in the field of gene therapy little progress has been done.Mate...
متن کاملGlass needle-mediated microinjection of macromolecules and transgenes into primary human blood stem/progenitor cells.
A novel glass needle-mediated microinjection method for delivery of macromolecules, including proteins and larger transgene DNAs, into the nuclei of blood stem/progenitor cells was developed. Temporary immobilization of cells to extracellular matrix-coated dishes has enabled rapid and consistent injection of macromolecules into nuclei of CD34(+), CD34(+)/CD38(-), and CD34(+)/CD38(-)/Thy-1(lo) h...

Background and purpose: Stress is one of the decisive factors in infertility, which can interfere with spermatogenesis and reduce spermatozoa. Considering the immobilization stress-induced infertility disorders, this study aimed at examining the protective effect of selenium yeast cell wall (as an antioxidant) on in vitro fertilizing ability following immobilization stress in adult male rats. ...
متن کاملDDX3X regulates cell survival and cell cycle during mouse early embryonic development
DDX3X is a highly conserved DEAD-box RNA helicase that participates in RNA transcription, RNA splicing, and mRNA transport, translation, and nucleo-cytoplasmic transport. It is highly expressed in metaphase II (MII) oocytes and is the predominant DDX3 variant in the ovary and embryo. However, whether it is important in mouse early embryo development remains unknown. In this study, we investigat...
