Recent advances in the use of pluripotent cells allow try growing organs for later transplantation to the donor's own cells.

However it seems that the in vitro cultivation of various organs will present different degrees of difficulty. So we can consider that the formation of the central nervous system or the heart will be the indicators of the state of research in the area of organ culture due to the functional needs of each:

(1) From the central nervous system by the implications for the influence of the size of the ganglion pairs in the abilities of the individual.

(2) Cultivation for the cardiac mechanical activity of the future heart.

The current state of technology has allowed to cultivate a brain organoid than 4-5 mm diameter by the Dr. Knoblick of Vienna and the team of researchers from the University of Edinburgh team from pluripotent human cells.

As technology for cultivation of the heart is known to researchers at the University of Minnesota have achieved cultivate stem cells in a collagen support of a human heart from a donor, obtaining a body capable of beating regularly .

Previously it had news of the cultivation of lungs and livers in mice and urethras and bladders of human urine.
