Yolk formation in a stony coral Euphyllia ancora (Cnidaria, Anthozoa): insight into the evolution of vitellogenesis in nonbilaterian animals.
Vitellogenin (Vg) is a major yolk protein precursor in numerous oviparous animals. Numerous studies in bilateral oviparous animals have shown that Vg sequences are conserved across taxa and that Vgs are synthesized by somatic-cell lineages, transported to and accumulated in oocytes, and eventually used for supporting embryogenesis. In nonbilateral animals (Polifera, Cnidaria, and Ctenophora), w...
متن کاملI-31: Reconstruction of Human Endometrium from Somatic Stem Cells
s:3115:"Background: During reproductive life, the human endometrium undergoes around 500 cycles of growth, breakdown and regeneration. This outstanding regenerative capability is the basis for cyclic endometrial preparation and its dysfunction is involved in pathological disorders. Endometrial regeneration is mediated by the existence of a specialized endometrial stem cell (SC) population recen...
متن کاملSignaling networks in somatic cells and oocytes activated during ovulation.
The molecular and structural changes in the follicle triggered by the gonadotropin luteinizing hormone (LH) at ovulation require complex interactions between somatic cells and the oocytes. It is well established that the signals originating from the oocytes play an essential role in orchestrating the growth and development of the follicle. Conversely, the exact contribution of local signals in ...
متن کاملEpigenetic reprogramming in somatic cells induced by extract from germinal vesicle stage pig oocytes.
Genomic reprogramming factors in the cytoplasm of germinal vesicle (GV) stage oocytes have been shown to improve the efficiency of producing cloned mouse offspring through the exposure of nuclei to a GV cytoplasmic extract prior to somatic cell nuclear transfer (SCNT) to enucleated oocytes. Here, we developed an extract of GV stage pig oocytes (GVcyto-extract) to investigate epigenetic reprogra...
متن کاملReprogramming of human somatic cells using human and animal oocytes.
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...
