Abstract Study question What are the subtypes of immune cells present in upper and lower parts uterus at time frozen embryo transfer (FET)? Summary answer Our study is first confirming different cell subsets freshly collected uterine fluid transfer. known already Although endometrial receptivity a key factor influencing implantation both naturally conceived assisted reproductive technology (ART...

Embryo implantation requires healthy uterine endometrium for natural or assisted reproductive technology conception. However, in presence of any endometrial anatomical abnormality disease, is affected. Uterine polyps are over growths cells that extend into the cavity. They usually noncancerous. There can be one many polyps. range size from a few millimeters to several centimeters larger. may ca...

The developmental capacity of (a) single blastomeres of 4-cell embryos, (Jb) pairs of blastomeres of 8-cell embryos and (c) single blastomeres of 8-cell embryos was studied. The blastomeres were inserted into evacuated foreign zonae pellucidae, embedded in agar, transferred to ligated oviducts of dioestrous ewes, and recovered when their total age was 5-Jto 6̂ days. At lecovery the majority of e...

Exosomes are nanoparticles (∼100 nm diameter) released from cells, which can transfer small RNAs and mRNA via the extracellular environment to cells at distant sites. We hypothesised that exosomes or the slightly larger microvesicles (100-300 nm) are released from the endometrial epithelium into the uterine cavity, and that these contain specific micro (mi)RNA that could be transferred to eithe...
