In-depth review on the impending reality of 3D printed organs

Being able to 3D print a full-sized adult human heart just got much closer

Growth pattern. Forty-two hours after they began to differentiate, embryonic cells are clearly segregating into endoderm (red), mesoderm (blue) and ectoderm (black). Researchers say the key to achieving this patterning in culture is confining the colonies geometrically.

Using geometry, researchers coax human embryonic stem cells to organize themselves
