Histological Evaluation Of Cryopreserved Ovaries In Autologous Abdominal Transplant To NaïVe, Outbred, Cd1, Mice, Wentia Elissa Ford
Histological Evaluation Of Cryopreserved Ovaries In Autologous Abdominal Transplant To NaïVe, Outbred, Cd1, Mice, Wentia Elissa Ford
Biological Sciences Theses & Dissertations
This study showed that fresh and frozen-thawed mouse ovaries would maintain viable primordial or primary follicles post-autologous transplantation. Furthermore, with appropriate hormonal stimulation, these early-stage follicles were shown to develop into Graafian follicles containing a metaphase II antral ovum. Partially sliced ovaries were transplanted into the abdominal cavity of naive, outbred, CD1, white mice. Hormonal stimulation with pregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin (hCG) one week after the autologous transplantation stimulated variable degrees of follicle and ovum maturation within the ovarian tissue. There were no major morphological differences observed between the four groups, three treatment and one …
Map Kinases In Cynomolgus Monkey Sperm Hyperactivation, Emily Nicole Haynes
Map Kinases In Cynomolgus Monkey Sperm Hyperactivation, Emily Nicole Haynes
Biological Sciences Theses & Dissertations
Mammalian sperm exhibit characteristic motility patterns, termed hyperactivated (HA) motility, associated with completion of capacitation. In cynomolgus monkey (Macaca fascicularis) sperm, this HA motility is dependent in vitro upon the addition of exogenous cyclic nucleotide mediators, caffeine and dibutyryl-cyclic adenosine monophosphate (dbcAMP). Previous reports have shown protein tyrosine phosphorylation to be an integral component of this caffeine- and cAMP-stimulated HA motility. This study investigated the involvement of the mitogen-activated protein (MAP) kinase-signaling cascade. Semen specimens were collected in Talp-HEPES medium from proven breeders via electroejaculation. After washing, sperm were incubated in the presence and absence of the MAP …
The Effects Of 712-Dimethylbenz (A) Anthracene On Ovarian Steroidogenesis And Uterine Growth In The Mouse, Jeffrey Lynn Clark
The Effects Of 712-Dimethylbenz (A) Anthracene On Ovarian Steroidogenesis And Uterine Growth In The Mouse, Jeffrey Lynn Clark
Biological Sciences Theses & Dissertations
It has been previously demonstrated that 7,12-dimethylbenz(a) anthracene (DMBA) is an initiator of ovarian granulosa cell tumors. It is also known that DMBA leads to destruction of primordial oocytes, and that tumor induction may involve the interaction of pituitary gonadotropins. However, the effects of DMBA on ovarian steroidogenesis and uterine growth in relation to the tumorigenic process have not been investigated. Therefore, the present study was conducted to examine these parameters using adult C57Bl/6N mice treated in proestrus and diestrus II with 0.1 ml corn oil with or without 1.5 mg DMBA and killed 44 hours later. The uteri and …
