"extracted cells from leaves flowering plant... stored liquid medium... treated... gel-based medium enriched with nutrients and hormones.... gave rise to new plant cells... by changing hormonal concentration in gel medium... control physical and mechanical properties... plant material that contained high hormone concentrations turned stiff... 3D print custom-designed structures... For three months lab-printed plant material was incubated in dark... grow at a rate twice that of a regular tree"
