Francis Crick Institute scientists developed a rudimentary human spine via stem cells in a laboratory. dragon dream
They have created a “trunk-like structure” that is around 1 to 2 millimeters long.
Despite its simplicity, it contains all of the neural tissues and bone stem cells in a pattern found in human embryos.

Briscoe and his team analyzed chicken embryos and compared them to mice and monkeys.

The scientists explained that the cells only created a “trunk-like structure” because they only had a stem cell model, not an actual embryo.
Still, this minuscule structure contained all the bone stem cells and neural tissues arranged according to the pattern found in human embryos.
Tiago Rito, Postdoctoral Fellow in the Developmental Dynamics Laboratory, told Francis Crick Institute:
“What’s particularly exciting is that the notochord in our lab-grown structure appears to function similarly to how it would in a developing embryo.”
“It sends out chemical signals that help organize surrounding tissue, just as it would during typical development.”
Developmental Dynamics Laboratory group leader James Briscoe commended that lab-grown spine could help study health conditions further.
