WebBackground: Early development of fish relies on maternal gene products (i.e. mRNA and proteins) stored into the oocyte during oogenesis as the genome of the embryo does not start to be transcriptionally active until the MZT (Maternal-to-Zygotic Transition) that occurs during the Mid-Blastula Transition (MBT). A previous genomic analysis of fish eggs … Web1 de fev. de 2010 · In the cystic mode of spermatogenesis in fish, germ cell number and volume increases greatly per cyst during the spermatogenic process. Therefore, it is not surprising that the number of Sertoli cells per cyst also increases, which occurs in a predictable manner.
