Objective To convert blastocyst (BL) morphological grade and BL day into a numeric blastocyst score (BS). Design Retrospective cohort study. Setting Academic center. Patient(s) A total of 5,653 BL of known impl
按照双方染色体核型,将PGT-A分为女方染色体多态性变异(女方多态组)、男方染色体多态性变异(男方多态组)、双方染色体多态性变异(双方多态组)和染色体正常组;将IVF患者分为女方染色体多态性变异(女方多态组)、男方染色体多态性变异(男方多态组)和染色体正常...
Sox2 is expressed in the inner cell mass of the blastocyst, and Sox2 deficiency impairs the formation of the pluripotent epiblast, which leads to death in utero25. Together with the transcription factors c-Myc, KLF4 and Oct-4, Sox2 can reprogram differentiated somatic cells into induced ...
The more advanced developmental stage of blastocyst may be a possible reason for these higher rates (3, 7, 8). On the other hand, it is well established that pregnancy rates are affected by the average embryo score and that the chance for a successful outcome diminishes with each successive...
Then cells were trypsinized and 2/3 were frozen for later blastocyst injection while 1/3 was cultured on gelatinized 24-well plates for another 6–10 days for southern blot analysis. Blastocyst injection. Superovulation of 4–8 week old female mice was achieved by i.p. injection of 7...

CUMULATIVE LIVE BIRTH RATE PER RETRIEVAL IS SIGNIFICANTLY HIGHER WITH PGT-A VS. NO PGT-A WITH SINGLE BLASTOCYST TRANSFER IN WOMEN 35 TO 40 YEARS, BUT NOT < 35: AN ANALYSIS OF 56,469 CYCLES FROM SART. P-423美国一研究团队 目的 ...
AURKA is an essential kinase, as the corresponding knock-out mice die before the 16-cell stage. In addition, germ line AURKA deficiency causes embryonic death at the blastocyst stage. AURKA also regulates meiotic maturation and fertilization of mouse oocytes [30]. AURKA is expressed in all somat...
In assisted reproduction by IVF or ICSI, the rate at which embryos develop to the blastocyst stage is influenced by the fertilization method used: a split IVF/ICSI study. J Assisted Reprod Genetics. 2019;36:647–54. 14. Stimpfel M, Jancar N, Vrtacnik-Bokal E, Virant-Klun I. ...
Once the targeted mESC clone is verified, the cells can either be injected into the cavity of embryon- ic day E3.5 blastocyst stage embryos or aggregated with 1260 GENES & DEVELOPMENT E2.5 morula stage embryos (Behringer et al. 2014). Because not all chimeras have mESC...
