Whence Meiosis?

Effect of Β-Mercaptoethanolon Resumption of Meiosis, in Vitro Maturation and Development of Immature Mouse Oocyte Treated With Dehp (Di-(2-Ethylhexy) Phathalae)

Purpose: The aim of this study was evaluated the effect of β -mercaptoethanol on resumption of meiosis, In vivo maturation of immature mouse oocytes treated with DEHP and embryo development. Materials and Methods: NMRI mouse strain (4-6 weeks) were treated daily with 50,µI DEHP Group 1: 121 immature oocytes were matured in MEM-α medium contain FCS 5%, hCG 7.5 IU/ml, rFsH 100mIU/ml, Group 2: 12...

Evaluation of Embryos Derived from in vitro Fertilized Oocytes Reconstructed by Meiosis-II Chromosome Transplantation from Aged Mice to Ooplasms of Young Mice

Background To assess embryos derived by the transfer of meiosis-II chromosomes (M-II-t) from aged mice oocytes into ooplasms from younger mice to overcome the problem of age-related decline in female fertility. MaterialsAndMethods The developmental capacity karyotype and ultrastructure of reconstructed oocytes derived from meiosis-II chromosome transplantation from aged mice into the ooplasms o...

I-51: The Role of the Transcription FactorGCNF in Germ Cell Differentiation and Reproductionin Mice

The germ cell nuclear factor (GCNF) is a member of the nuclear receptor super family of transcription factors. GCNF expression during gastrulation and neurulation is critical for normal embryogenesis in mice. GCNF represses expression of the POU domain transcription factor Oct4 during mouse post-implantation development in vivo. Oct4 is thus down-regulated during female gonadal development, whe...

Nineteenth-Century Literary Criticism: Anne K. Mellor (essay date 1988)

. . .. How does Mary Shelley conceive of nature as such? In other words, what is nature, both the external world and human nature? Frankenstein insistently raises this question.
