Turnover of embryonic messenger RNA in preimplantation mouse embryos.
We have estimated the average half-life of embryonic messenger RNA in mouse embryos at two stages of preimplantation development. Embryos were collected at 48 and 75 h post-hCG and cultured overnight in the presence of [3H]uridine. Beginning at 65--68 h (morulae) or 92--94 h (early blastocysts), the label was withdrawn and replaced with unlabelled uridine, and samples were taken at intervals th...
متن کاملI-13: Transcriptome Dynamics of Human and Mouse Preimplantation Embryos Revealed by Single Cell RNA-Sequencing
Background: Mammalian preimplantation development is a complex process involving dramatic changes in the transcriptional architecture. However, it is still unclear about the crucial transcriptional network and key hub genes that regulate the proceeding of preimplantation embryos. Materials and Methods: Through single-cell RNAsequencing (RNA-seq) of both human and mouse preimplantation embryos, ...
متن کاملMessenger characteristics of nascent bacteriophage RNA.
The proteins initiated in vitro by nascent bacteriophage f2 RNA strands attached to isolated replicating structures have been analyzed. The observations confirm that coat protein is the major product initiated and completed. Nascent strands direct the initiation of viral maturation protein in amounts similar to the maximum levels observed in vivo; this synthesis is independent of translation of...
متن کاملEffect of Li+ on preimplantation mouse embryos.
Two-cell mouse embryos were cultured in vitro for different periods in a medium in which NaCl was partially replaced by LiCl at concentrations ranging from 1 to 30 mM. The relative cell number diminished according to increasing LiCl concentrations but the onset of blastulation was not affected, thus resulting in blastulae with fewer cells than normal and with a reduced or absent inner cell mass...
متن کاملPreimplantation development of gynogenetic diploid mouse embryos.
Diploid gynogenetic mouse embryos were produced in a three-step procedure: fertilization in vitro, suppression of the 2nd polar body formation by Cytochalasin B, and microsurgical removal of the male pronucleus. The operated eggs were transplanted to the oviduct of recipient females for 72 or 96 h. The overall recovery rate was 73%, but compacted morulae and blastocysts constituted only 28.6% o...
