...rotein in the nucleus of oocytes which can promote in vitro nucleosome formation. In this study, to improve the efficiency of SCNT in Banna Mini-pig Inbred Line (BMI), we obtained the recombinant nucleoplasmin (Npm) by using a prokaryotic expression system and compared the difference on the developmental effects between exogenous Npm and its structural analog, polyglutamic acid (PGA). We chose the pMD18-T vector for Npm expression and transformed E. coli BL21 ...

For the gonad differentiation related genes, the expression profiles of Cyp19A and Cyp19B show a pattern of increase in short time and low concentration, but decline in long time and high concentration. Arα has a trend of increases, ERα shows downwards trend. Dax and Foxl2 are female-biased genes, their expression profiles show simil...

Sheep follicular fluid (SFF) was collected from different ovaries and supplemented to the in vitro maturation (IVM) media with proportions 0%, 10%, 20% and 40%. Oocyte maturation was assessed in different treatments and then cumulus-oocyte complexes were us...

The theca of atretic mature oocytes was hypertrophied and persisted to form the interstitial cells, whereas the granulosa cells were regressed and disappeared. Erythrocytes and leukocytes were also detected at the advance stage of atresia. Apoptosis in the granulosa cells were clearly detected. The chromatin condensation against the nuclear envelope, cell shrinkage, surface...

To study the effects of mechanical damage from microopetations on embryo development, we analyzed 60 the spent culture media of porcine parthenogenetic embryos experienced different types of microopetation using Raman spectroscopy. The results showed that Group II with the puncture of egg zona and plasma membrane had the highest cleavage rate and blas...

The aim of this study was to identify the polymorphisms in the exon 11 of bLHR/HhaI gene (SNP g.1553C>T) and its association with service per conception (S/C) of Pasundan cows of West Java, Indonesia. Total of 147 Pasundan cows were used in this study. The PCR-RFLP analysed three genotypes of CC (0.11), CT (0.57) and TT (0.32) were detected in the Pasundan bLHR/Hha...

...Artificial activation of oocyte is a one of key step in cloning. Strontium chloride (SrCl2), a calcium oscillation inducing salt, is commonly used for the artificial activation mouse oocytes; however, limited reports are available to evaluate its negative impact. The objective of this study was to optimize the concentration of SrCl2 for artificial activation of mouse oocyte

The expression of Gas6 in the process of follicular development was studied by immunohistochemical staining, immunofluorescence, QRT-PCR and western blot. Immunohistochemical staining results showed that Gas6 was expressed in the oocytes, especially the nucleus, from the primary to preovulatory stages. The furthe...

Immunohistochemical, BVDV antigen was detected in ear notch, ovaries, fallopian tubes and uterus of one cow (1/30) (PI animal). Whereas, BVDV antigen was detected only in the genital organs of acutely infected animals (2/30) but ear notch was negative. The positive BVDV antigen was clearly ob...

Oocyte maturation appears to be a simple step, but it is a very complex process. Maturation of oocytes include several changes at the cytoplasmic and nuclear levels that makes the

Primordial pregranulosa follicular cells initiate activation of primordial follicle and govern the development of dormant oocytes. The primordial follicles take about 6 months to grow and develop to ovulatory graafian follicles in cattle and humans. Growth of preantral follic...
