Scientists have discovered a new subset of human embryonic stem cells that closely resemble cells present in the 8-cell human embryo.

Researchers have developed a rapid and controllable method to convert pluripotent stem cells into totipotent embryo-like cells, which could be used in future for regenerative medicine.

Cells “dance” as they draw together during early embryo development. Cells within an 8-cell embryo shown to ‘dance’ to the same rhythm.

Researchers have published their latest work describing a new subset of human embryonic stem cells that closely resemble the cells present at the genomic "wake up call" of the 8-cell embryo stage in ...

8 million cells: virtual embryo shows organs forming in exquisite detail Model used to create a cellular ‘hologram’ of a mouse embryo could be used to visualize development in any species. By ...

Is a human embryo, at its earliest stages, a human life? On the heels of President Bush's first-ever veto of legislation that would have expanded federal funding for embryonic stem-cell research ...

By measuring surface tensions in developing mouse embryos, Maître and colleagues show that compaction of the blastomere stage embryo is driven by downregulation of actomyosin at cell–cell contacts.

Statistical analysis of the successfully integrated data revealed that the iBM cells reprogrammed by Dr. Yoshihara and his team showed the highest similarity to the 8-cell-stage embryo across both ...

During animal development, cells divide and arrange themselves in a coordinated way, eventually forming the embryo. The cells ...

Researchers have discovered a new type of stem cell that resembles cells in the early human embryo during the transition of 'genomic power' from mother to embryo. During this major developmental ...

During embryonic development, thousands of cells divide and move collectively to sculpt the main body axes. Understanding the mechanisms that coordinate this collective behavior remains a significant ...

Scientists have created “synthetic” mouse embryos from stem cells without a dad’s sperm or a mom’s egg or womb. The lab-created embryos mirror a natural mouse embryo up to 8 ½ days after ...
