Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

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 ...

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

Researchers have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. This is ...

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 ...

A new study from the MRC Laboratory of Medical Sciences (LMS) in London, UK reveals how ancient viral DNA once written off as "junk" plays a crucial role in the earliest moments of life. The research, ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...
