It has taken more than five years of graft, but at long last approval has been given for the first clinical trial using human embryonic stem cells (hESCs). These cells can develop into all tissues of the body.
Graft here refers to the process of transferring stem cells from one place (source) to a second area where it is hoped they will grow. It is also called 'stem cell transplantation'

@oristarA,
Yes, it means hard work, and is a pun on the scientific method of grafting cells.
Graft: "shoot inserted into another plant," late 15c., from O.Fr. grafe "graft, stylus," from L. graphium "stylus," from Gk. grapheion "stylus," from graphein "to write" (see -graphy). So called on resemblance of a stylus to the pencil-shaped shoots used in grafting.
Stumble It!
