A novel isolator-based system promotes viability of human embryos during laboratory processing

, 2012
In vitro fertilisation (IVF) and related technologies are arguably the most challenging of all cell culture applications. The starting material is a single cell from which one aims to produce an embryo capable of establishing a pregnancy eventually ...

Acceptance of donor eggs, donor sperms, or donor embryos in Indian infertile couples

Journal of Human Reproductive Sciences, 2018
Context: The reduction or loss of natural fertility is deeply painful in couples that are considering the use of donor gametes or donor embryos. This is the first study to assess the acceptability of donor gametes or embryos in Indian population.

Increased Risk of Sarcomas in Children With Congenital Anomalies: Findings From the Genetic Overlap Between Anomalies and Cancer in Kids (GOBACK) Registry Linkage Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric sarcomas are a heterogeneous group of tumors that contribute disproportionately to cancer mortality in children. Although congenital anomalies are among the strongest known risk factors for childhood cancer, the risk of specific sarcoma subtypes among affected individuals has not yet been thoroughly evaluated.

Feline Wharton’s jelly-derived mesenchymal stem cells as a feeder layer for oocytes maturation and embryos culture in vitro

Frontiers in Veterinary Science, 2023
IntroductionDue to their capacity to release growth factors and cytokines, co-culture using mesenchymal stem cells has been considered a good alternative to promoting the maturation of the oocytes and the embryo’s development quality in vitro in ...

Morphokinetic behavior of euploid and aneuploid embryos analyzed by time-lapse in embryoscope

Journal of Human Reproductive Sciences, 2016
BACKGROUND: Embryonic aneuploidy may result in miscarriage, implantation failure, or birth defects. Thus, it is clinically necessary to avoid the selection of aneuploid embryos during in vitrofertilization treatment.
