The shaping of human embryos begins 4 days after fertilization with a process called compaction, during which the 8 to 16 cells of the embryo come into close contact to form a tighter structure. Four ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

Scientists have uncovered a new way embryonic cells divide when conventional mechanisms fail. Cell division underpins all ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

Collaborative work has developed a cell culture system that differentiates human pluripotent stem cells to amniotic ectoderm and surface ectoderm based on cell density. Research conducted by Dr Shota ...

During embryonic stem cell (ESC) development, pluripotent stem cells transition from a naïve state into a primed state before they take their first steps toward a lineage commitment. Jacob Hanna, a ...

Caltech researchers have developed a powerful new method for creating embryo-like structures from stem cells that could transform how we study fertility. Subscribe to our newsletter for the latest sci ...
