Notochord Guides Neural and Spinal Formation

Scientists have developed human stem cell models containing the notochord, a critical tissue that guides spine and nervous system formation during embryonic development. Using precise chemical signals inspired by natural processes in chicken, mouse, and monkey embryos, the researchers successfully coaxed human stem cells to form a notochord and a miniature trunk-like structure. This innovation mirrors key features of human development and could advance the study of spine-related birth defects and conditions like intervertebral disc degeneration.

Organoids and Embryo Models: Redefining Human Individuality?

Advances in organoids and embryonic models raise questions about human individuality. A new study argues these models can reinforce, not weaken, the concept of human individuality when viewed through personhood and sentience frameworks. Researchers emphasize that current technologies are far from achieving personhood in embryo models or organoids. The ethical focus should remain on the wellbeing of actual persons and sentient beings.

‘Mini Brain’ Organoids Grown in Lab Mature Much Like Infant Brains

Brain organoids, or mini-brains, created from human stem cells appear to develop in much the same way as a human brain. The organoids follow an internal clock that guides their maturation in sync with the timeline for human brain development.

Not ‘brains in a dish’: Cerebral organoids flunk comparison to developing nervous system

Hailed by many as a breakthrough for neuroscience research, a new study reports brain-in-a-dish models may not be as useful as reported previously. The study reports instead of differentiating normally into the brain's distinctive cell types, cerebral organoids often express mixed genes normally found in different kinds of cells.
