In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a ...

The image shows centromeres (white) at the edge of the nucleus (blue) shortly before meiosis begins in a mouse germ cell (Huang et al., 2026). In our cells, our DNA carries chemical or ‘epigenetic’ ...

Even in the best-case scenario, when fertility clinics transfer chromosomally normal embryos into a would-be mother’s uterus, the procedure only leads to a live birth half of the time. Some embryo ...

New stem cell-based embryo model reveals previously unknown communication between early tissues that become the spine and muscles in the central part of the body. From the moment an embryo starts to ...

During early development, tissues and organs begin to form through the shifting, splitting, and growing of many thousands of cells. A team of researchers headed by MIT engineers has now developed a ...

Cancer cells are known to reawaken embryonic genes to grow. A new study reveals the disease also hijacks the proteins, or "editors," that control how those genes are read. The findings, published in ...

The method could one day become a treatment for infertility A decade of further research needed, scientists say The process overcomes an obstacle that stymied previous attempts Significant safety ...

Creating human eggs from adult cells just got one step closer to reality. A technique used in cloning combined with fertilization and a bit of chemical coaxing caused human skin cells to produce eggs ...
