A research team headed by Prof. Jacob Hanna at the Weizmann Institute of Science has created complete models of human embryos from stem cells cultured in the lab—and managed to grow them outside the ...

The generation of human model systems is critical to reveal the mechanisms underlying the aging processes and to gain insights on interventions that extend the human organism’s health/life span. The ...

For decades, animal models have been the gold standard for preclinical testing of potential drugs. Yet, even the best animal models are not perfect. For example, small rodent species with engrafted ...

Human-based in vitro models, such as organoids and organs-on-chips, may have the potential to replace certain animal models in preclinical research. But how much ‘human’ is needed in these models?
