BACKGROUND We previously demonstrated embryotrophic actions of maternal (oocyte-derived) follistatin during bovine early embryogenesis. Classical actions of follistatin are attributed to inhibition of activity of growth factors including activins and bone morphogenetic proteins (BMP). However, temporal changes in BMP mRNA in early bovine embryos and the effects of exogenous BMP on embryo develo...
There is renewed interest in using animal oocytes to reprogram human somatic cells. Here we compare the reprogramming of human somatic nuclei using oocytes obtained from animal and human sources. Comparative analysis of gene expression in morula-stage embryos was carried out using single-embryo transcriptome amplification and global gene expression analyses. Genomic DNA fingerprinting and PCR a...
Background: Cryopreservation of farm animal embryos is nowadays a widely used routine technique. Success in cryopreservation of form animal depends on many factors including: freezing medium, types of cryoproctants, melting process, lipid content in ooplasm and oocyte quality It has been found that immature Oocytes with reduced reproductive performance or slaughtered at the end of their use are...
