Artificial Embryos Made from Stem Cells Raise Ethical Issues

Stem cells (so-called “master cells”) are unique and important in the body because they can do almost anything, and scientists have only begun to discover their potential. That’s why researchers’ use of them has created controversy, attracting the attention of scientists, policymakers, and bioethicists across the globe. Stem cells can transform into any of the… Read More »

An important step for regenerative medicine: Human blood cells can be directly reprogrammed into neural stem cells

Stem cells are considered to be the all-rounders of our tissues: they can multiply indefinitely and then – if they are pluripotent embryonic stem cells – generate all conceivable cell types. In 2006, the Japanese scientist Shinya Yamanaka recognized that such cells could also be produced in the laboratory – from mature body cells. Four… Read More »
