A mature intestinal organoid, grown from human pluripotent stem cells and an artificial growth-promoting hydrogel RICARDO CRUZ-ACUÑ The, GEORGIA TECH To cultivate organoids within culture, scientists bathe them in growth-promoting materials based on mice. But this limits their use in treating individual diseases due to the  risk for zoonotic infections. To resolve this problem, researchers engineered a synthetic gel that can also perform the job.
