Fetal #cells can be traced back to the first day of #embryonic development.

Though more than 8 million babies have been born through in vitro fertilization (IVF), 70% of IVF implantations fail. As IVF is becoming a more common route to pregnancy in cases of infertility, there is a need for better understanding of embryonic development at this early stage.

A collaboration between research groups at the University of California, TU Dresden in Germany and Cedars-Sinai Guerin Children's in Los Angeles has identified a mechanism by which embryonic cells organize themselves to send signals to surrounding cells, telling them where to go and what to do. While these signaling centers have been known to science for a while, how individual cells turn into organizers has been something of a mystery.

Bricklayer, banker, teacher—choosing a career is one of the most exciting and important decisions in our lives. At the beginning of embryonic development, our cells are also faced with this decision. Some of them become blood cells, others muscle cells and still others become nerve cells.
"Here, we examine changes in rRNA 2′-O-me during mouse brain development and tri-lineage differentiation of human #embryonic stem cells (hESCs). We find distinct alterations between #brain regions, as well as clear dynamics during cortex development and germ layer differentiation. We identify a #methylation site impacting #neuronal #differentiation."

Number of #DNA copies influences the #cell #death process that shapes organs during #embryonic development: Study.
During embryonic development, the programmed death of certain cells plays an essential role in shaping organs and allowing proper growth. This cell death is in some cases an effect of autophagy, a key cellular process responsible for the degradation and recycling of damaged or unwanted cellular components and which, taken to the extreme, may end up eliminating the cell itself.

Researchers have spotted how specific proteins within the chromosomes of roundworms enable their offspring to produce specialized cells generations later, a startling finding that upends classical thinking that hereditary information for cell differentiation is mostly ingrained within DNA and other genetic factors.
