When mammalian cells die, they do not simply dissolve away. Instead, they are actively deconstructed and destroyed in defined and organized ways by various regulated cell-death mechanisms. One of ...

This study provides valuable insights into the role of the NF-kB and IKK signaling pathways in γδ T cell development and survival, using robust genetic mouse models. While the research is ...

Chimpanzee naive pluripotent stem cells (PSCs) can now be grown in cellular cultures, reveals a recent study. They successfully created chimpanzee early embryo models, called 'blastoids,' and found ...

In addition to endodermal and mesodermal cells, alcohol causes changes in DNA methylation in ectodermal cells (in blue), from which the nervous system and brain develop. During the tightly regulated ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

During animal development, cells divide and arrange themselves in a coordinated way, eventually forming the embryo. The cells communicate with one another during this process through cell-surface ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

Bioengineering researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a soft, thin, stretchable bioelectronic device that can be implanted into a ...
