Human Embryology

An analysis of rhetorical beauties in the interpretation of verses on embryology

The Holy Quran in various verses has explained stages of human development in embryonic period. The Quran describes these stages to prove the possibility of human resurrection after death. The present study seeks to substantiate this point that these verses, which contain scientific hints and wonders, have also rhetorical and phonetic beauty. The literary and scientific interpretation of the ve...

Human Trophoblast Progenitor Cells Express and Release Angiogenic Factors

Trophoblast stem cells develop from polar trophoectoderm and give rise to the cells that generate the placenta. Trophoblast cells are responsible for the uterinal invasion and vascular remodeling during the implantation of the embryo. However this knowledge is not yet to be confirmed for trophoblast progenitor cells (TPCs). In this study, we aimed to demonstrate that human TPCs (hTPCs) express ...

The Effect of Prolonged Culture of Chromosomally Abnormal Human Embryos on The Rate of Diploid Cells

Background A decrease in aneuploidy rate following a prolonged co-culture of human blastocysts has been reported. As co-culture is not routinely used in assisted reproductive technology, the present study aimed to evaluate the effect of the prolonged single culture on the rate of diploid cells in human embryos with aneuploidies. MaterialsAndMethods In this cohort study, we used fluorescence in ...

Human Fertilisation and Embryology Authority (1991- )

In 1991, the United Kingdom established the Human Fertilisation and Embryology Authority (HFEA) as a response to technologies that used human embryos. The HFEA is a regulatory power of the Health and Social Services Department in London, UK, that oversees the implementation of reproductive technologies and the use of embryos in research within the United Kingdom. It establishes protocols by whi...

Human Fertilisation and Embryology Act (1990)

The Human Fertilisation and Embryology Act 1990 established the legal framework that governs infertility [3] treatment, medical services ancillary to infertility [3] treatment such as embryo storage, and all human embryological research performed in the UK. The law also defines a legal concept of the parent of a child conceived with assisted reproductive technologies. Section Five of the Act es...
