Growing organs from stem cells. Surgeon Paolo Macchiarini, Professor of Regenerative Surgery at Karolinska Institutet is famous for being the first man to grow (and transplant) a fully working human organ using adult stem cells. That was back in 2008 and since then five similar operations have been carried out.
There are several sources of stem cells. Pluripotent stem cells can be isolated from human embryos that are a few days old. Cells from these embryos can be used to create pluripotent stem cell lines âcell cultures that can be grown indefinitely in the laboratory.Pluripotent stem cell lines have also been developed from fetal tissue (older than 8 weeks of development).In late 2007, scientists identified conditions that would allow some specialized adult human cells to be reprogrammed genetically to assume a stem cell-like state. Pluripotent stem cells can give rise to any type of cell in the body except those needed to support and develop a fetus in the womb. 2  Stem cells that can give rise only to a small number of different cell types are called multipotent.
