Expression of growth hormone gene during early development of Siberian sturgeon (Acipenser baerii)
The mRNA expression of growth hormone (GH) gene in early development stages of Siberian sturgeon was investigated using RT-PCR method. Samples were collected from unfertilized eggs up to 50 days post hatched (dph) larvae in 11 different times. Ribosomal protein L6 (RPL6) transcripts were used as the internal standard during quantification of GH mRNA expression. The results showed that the GH mR...
متن کاملGrowth and development of human adipose tissue during early gestation.
805 normal-for-age human embryos and fetuses were used to study early prenatal fat development. The investigation included observations on stages of fat morphogenesis at the light microscopic level and computerized image analyses of fat lobule size and number. The buccal fat pad was selected as a model system for the analyses. Fat tissue differentiates between the 14th and the 16th weeks: there...
متن کاملGrowth and Morphogenesis during Early Heart Development in Amniotes
In this review, we will focus on the growth and morphogenesis of the developing heart, an aspect of cardiovascular development to which Antoon Moorman and colleagues have extensively contributed. Over the last decades, genetic studies and characterization of regionally regulated gene programs have provided abundant novel insights into heart development essential to understand the basis of conge...
متن کاملP-52: Brain-Derived Neurotrophic Factor Promotes The Development of Human Ovarian Early Follicles during Growth In Vitro
Background Cryopreservation of ovarian cortex is increasingly used to preserve fertility before cancer therapy. Recently, studies show that Brain-derived neurotrophic factor (BDNF) may be involved in oocyte maturation. Brain-derived neurotrophic factor (BDNF) is member of neurotrophin family that has anti-apoptotic effects on nervous system. Recent researches show that it also plays key role in...
متن کاملPre-assembled Nuclear Pores Insert into the Nuclear Envelope during Early Development
Nuclear pore complexes (NPCs) span the nuclear envelope (NE) and mediate nucleocytoplasmic transport. In metazoan oocytes and early embryos, NPCs reside not only within the NE, but also at some endoplasmic reticulum (ER) membrane sheets, termed annulate lamellae (AL). Although a role for AL as NPC storage pools has been discussed, it remains controversial whether and how they contribute to the ...
