Concerns about latest researches by Juan Carlos Izpisua’s group

There is no doubting the importance of biomedical research carried out by Juan Carlos Izpisúa and his team (1). Their work is focused mainly on: a) the production of hybrids or human-animal chimeras; b) the development of methods to make the CRISPR technique more efficient (see...

Human–animal hybrid advisability. Human brain gene introduced into monkeys that seems to increase their intelligence

“Genetic changes should not be introduced in higher animals, as this raises bioethical uncertainties.” Chinese scientists have recently produced transgenic monkeys by introducing a human brain gene into the animals during their embryonic development (produci...

Neuroscience. New experiments with brain rekindle the bioethical debate

Neuroscience research, with the ultimate goal of deepening our knowledge of the human brain, about which we still know so little, is advancing rapidly (see HERE). Thus, major projects such as the “BRAIN Initiative” in the United States and the Human Brain Project (HBP) in Europe...

Human-sheep hybrids created for the first time to develop organs

Human-sheep hybrids have been created for the first time by scientists at Stanford University (see New advances and challenges in the production of human-animal chimeras). The scientists grew the embryos in a surrogate sheep, allowing them to gestate up to 3 weeks (see HERE )....
