The pitfalls of PGT-A and scoring of mosaic embryos

The pitfalls of PGT-A and scoring of mosaic embryos

Preimplantation genetic testing for aneuploidies (PGT-A) or formerly known as preimplantation genetic screening (PGS), is genetic testing for numerical (aneuploidy) and structural chromosomal aberrations in IVF-embryos. Most aneuploidies including several structural chromosomal aberrations are not compatible with

Blood vessels regulate fetal brain growth

Millions of neurons are generated during fetal development from progenitor cells that reside inside the embryonic brain. These neural progenitor cell (NPC)s divide many times to generate new neurons in a process termed ‘neurogenesis’. At each cell

A new role for a well-known hematopoietic factor (G-CSF) in placenta

Multiple growth factors produced in our organism by different types of cells promote a variety of biological responses related to cell proliferation, differentiation, survival, migration or death. The granulocyte colony stimulating factor (G-CSF) is a protein that

Tunicates : Can the study of obscure marine animals shed light on evolution?

Scientists agree that the current biological diversity on earth is the result of evolution: present life forms evolved from their ancestors by progressive modifications. The shape and behavior of an animal or a plant – what scientists

Maternal diabetes negatively affects the development of embryonic heart

Diabetes in pregnancy may negatively affect the developing fetus, neonate, and child. Poorly controlled maternal hyperglycemia before conception and during the first trimester is associated with an increased rate of major birth defects and spontaneous abortion. Cardiovascular
