Oogenesis is the process of formation and differentiation of primordial female germinative cells until the generation of a fertilized egg. This is an event that begins in the prenatal life and ends in the adult life of the female. During the growth and development of the female the oocyte pool is found in Diplotene of Meiosis I, more precisely in the state known as germinal vesicle (GV). …
The mammalian adult organism contains approximately two hundred different cell types. Each of these cells types possesses different functions and morphologies, which is controlled by the gene expression pattern. The chemical modifications present in the chromatin regulate gene expression and are called epigenetic modifications. The main functions of these modifications are to choose which…
The epigenome reprogramming mediated by somatic cell nuclear transfer (SCNT) created a huge expectation during the nineties, with several applications such as production of transgenic animals and cloning of high-genetic merit animals. The birth of Dolly was possible due to the perfect cellular synchronization, who was achieved through serum deprivation during the cell culture, inducing th…
Immediately after birth, mammalians possess an oocyte reserve estimated to be around 1 milion of cells.However, less than 1% of this pool will become a fertilizable oocyte. Part of this occurs due to a naturalprocess of selection during oogenesis. During the oocyte's growth phase, they must undergo a process ofcytoplasmic maturation, where they accumulate proteins, metabolites and RNAs es…
