For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Scientists are using human stem cells to create a structure that mimics a pre-embryo and can serve as a research alternative to a real one. They say these “blastoids” provide an efficient, ethical way ...

Our body's "blood factory" consists of specialized tissue made up of bone cells, blood vessels, nerves and other cell types. Now, researchers have succeeded for the first time in recreating this ...

Every year, more than 100 million animals are used globally in biomedical research, yet over 90% of drugs that appear effective in animal trials fail during human clinical testing. 1 This staggering ...

Animal models are established, important tools for preclinical safety and efficacy testing. Companies are advancing more “humanized” models to better reflect human responses, while at the same time ...
