Embryo-like structures concocted in a lab from skin tissue can help researchers peer into the “black box” of early human development.
Meanwhile, new frontiers in transplant and disease research could be opened by studies that introduce human cells into animals, or those creating tissue from stem cells that mimics organs, like kidneys and even brains.
But how far should this go? Where is the red line not to be crossed?
Guardrails need to adapt to deal with unexpected developments, notes bioethicist Insoo Hyun, who has…
