Isolation of Genes Differentially Expressed in Dominant and Subordinate Bovine Follicles

Autor: L.J. Hagemann, Bridget Sisco, Peter L. Pfeffer, Andrew N. Shelling

Publikováno v: Endocrinology. 144:3904-3913

In monoovulatory species such as cattle, unknown mechanisms lead to the selection of one of a cohort of developing ovarian follicles to assume dominance and continue to grow in each follicular wave. We have used suppressive subtraction hybridization

Development during single IVP of bovine oocytes from dissected follicles: Interactive effects of estrous cycle stage, follicle size and atresia

Autor: L.J. Hagemann, Susan E. Beaumont, Anita Schurmann, H. Robin Tervit, A. M. Ledgard, M. C. Berg, Martyn Donnison, A. James Peterson

Publikováno v: Molecular Reproduction and Development. 53:451-458

Previous work suggests that a number of factors such as follicle size, day of estrous cycle, and level of atresia influence the developmental potential of bovine oocytes in vitro. To understand better the interactions of these factors, 1299 follicles

Influence of the dominant follicle on oocytes from subordinate follicles

Autor: L.J. Hagemann

Publikováno v: Theriogenology. 51:449-459

As the oocyte grows within the follicle, a number of factors influence its health and developmental competence. These factors include follicle size, day of estrous cycle, level of atresia and influence of other follicles such as the dominant follicle

In vitro and early in vivo development of sheep gynogenones and putative androgenones

Autor: L.J. Hagemann, L. L. Weilert, A.J. Peterson, Rita S.F. Lee, H.R. Tervit

Publikováno v: Molecular Reproduction and Development. 50:154-162

Genomic imprinting, where only one of the two parental genes is expressed, occurs in many phyla. In mammals, however, this phenomenon has been primarily studied in mice, and to a lesser extent, in humans. To understand how genomic imprinting may affe

Embryonic cytoplasmic extracts rescue murine androgenones to the blastocyst stage

Autor: L.J. Hagemann, N.L. First

Publikováno v: Development. 114:997-1001

Androgenones (paternally derived genome) show a significant inability to form a blastocoele cavity. Eighty percent of these embryos die or arrest at earlier stages. Factor(s) from both normal and partbenogenetic late preimplantation embryos injected
