- Poor Embryo Development in Mouse Oocytes Aged In Vitro Is Associated with Impaired Calcium Homeostasis
[作者:Takahashi, T; Igarashi, H; Kawagoe, J; Amita, M; Hara, S; Kurachi, H,期刊:Biology of Reproduction, 页码:493-502 , 文章类型: Article,,卷期:2009年80-3]
- We examined whether impairment of intracellular Ca2+ homeostasis is related to poor embryo development in in vitro-aged oocytes. We found that in vitro aging of mouse oocytes affected the patterns of Ca2+ oscillations at...
- Functional Analysis of Male Mouse Haploid Germ Cells of Various Differentiation Stages: Early and Late Round Spermatids Are Functionally Equivalent in Producing Progeny
[作者:Ohta, H; Sakaide, Y; Wakayama, T,期刊:Biology of Reproduction, 页码:511-517 , 文章类型: Article,,卷期:2009年80-3]
- Spermiogenesis is a complex process consisting of three main phases: the round, elongating, and elongated spermatid phases. Although the germ cells acquire a haploid set of paternal chromosomes after meiosis, how functio...
- Heritable Imprinting Defect Caused by Epigenetic Abnormalities in Mouse Spermatogonial Stem Cells
[作者:Lee, JY; Kanatsu-Shinohara, M; Ogonuki, N; Miki, H; Inoue, K; Morimoto, T; Morimoto, H; Ogura, A; Shinohara, T,期刊:Biology of Reproduction, 页码:518-527 , 文章类型: Article,,卷期:2009年80-3]
- Male germ cells undergo dynamic epigenetic reprogramming during fetal development, eventually establishing spermatogonial stem cells (SSCs) that can convert into pluripotent stem cells. However, little is known about the...
- Characterization of Two Cytoplasmic Poly(A)-Binding Proteins, PABPC1 and PABPC2, in Mouse Spermatogenic Cells
[作者:Kimura, M; Ishida, K; Kashiwabara, SI; Baba, T,期刊:Biology of Reproduction, 页码:545-554 , 文章类型: Article,,卷期:2009年80-3]
- Mouse spermatogenic cells are known to contain at least two isoforms of cytoplasmic poly(A)-binding proteins, PABPC1 and PABPC2 (previously known as PABPT). In this study, we have characterized PABPC1 and PABPC2. PABPC2 ...
- Production of Piglets after Cryopreservation of Embryos Using a Centrifugation-Based Method for Delipation Without Micromanipulation
[作者:Li, RF; Murphy, CN; Spate, L; Wax, D; Isom, C; Rieke, A; Walters, EM; Samuel, M; Prather, RS,期刊:Biology of Reproduction, 页码:563-571 , 文章类型: Article,,卷期:2009年80-3]
- It is still difficult to successfully cryopreserve in vitro-produced (IVP) swine embryos, as they are sensitive to chilling due to the abundance of intracellular lipids. Mechanical delipation through micromanipulation is...
- Immunogold Evidence Suggests That Endoplasmic Reticulum Is the Site of Protamine-Type Protein Synthesis and Participates in Translocation of These Proteins into the Nucleus During Chara vulgaris Spermiogenesis
[作者:Poplonska, K; Kwiatkowska, M; Wojtczak, A; Polit, J,期刊:Biology of Reproduction, 页码:572-580 , 文章类型: Article,,卷期:2009年80-3]
- During spermiogenesis of an alga Chara vulgaris, which in many aspects resembles that of animals, histones are replaced by protamine-type proteins. Our earlier immunocytochemical studies showed that this replacement star...
