Amniotic sac in a dish: Stem cells form structures that may aid of infertility research
The first few weeks after sperm meets egg still hold many mysteries. Among them: what causes the process to fail, leading to many cases of infertility.

Newly identified small RNA fragments defend the genome when it's 'naked'
Our genomes are minefields, studded with potentially damaging DNA sequences over which hundreds of thousands of sentries stand guard. These sentries, called epigenetic marks, attach to the double helix at such spots and prevent ...
What makes stem cells into perfect allrounders
Researchers from the University of Zurich and the University Hospital Zurich have discovered the protein that enables natural embryonic stem cells to form all body cells. In the case of embryonic stem cells maintained in ...
Lab-created antibody could hold the secret to making stem cell therapy safer
Stem cells have paved the way for a new era in regenerative medicine, but their use is fraught with risk. Now, A*STAR scientists have developed an antibody that could make stem cell therapy safer.
Similarities in human and pig embryos provide clues to early stages of development
Scientists have shown how the precursors of egg and sperm cells – the cells that are key to the preservation of a species – arise in the early embryo by studying pig embryos alongside human stem cells.
Two-part system turns stem cells into whatever you want
Whether using embryonic or adult stem cells, coercing these master cells to convert to the desired target cell and reproduce flawlessly is difficult. Now an international team of researchers has a two-part system that can ...
A new method for creating safer induced pluripotent stem cells
Induced pluripotent stem cells (IPSCs) hold great promise in regenerative medicine, personalized medicine and drug discovery. However, while avoiding the ethical controversies associated with embryonic stem cells, they carry ...
Researchers develop a more precise and controlled method of engineering tissues from stem cells
Nothing beats nature. The diverse and wonderful varieties of cells and tissues that comprise the human body are evidence of that.
Stem cells in plants and animals behave surprisingly similarly
A new study from Lund University in Sweden shows that the behaviour of stem cells in plants and animals is surprisingly similar. The researchers were able to produce mathematical equations that reveal very small differences ...
The gene that starts it all
The formation of a human embryo starts with the fertilization of the oocyte by the sperm cell. This yields the zygote, the primordial cell that carries one copy each of the maternal and paternal genomes. However, this genetic ...
