“From a technical perspective, it’s plausible that within a decade, any two people may walk into a fertility clinic, have their cheeks swabbed, and leave as prospective parents. In a lab, their cells would be converted first into stem cells and then into sperm or eggs” : Hank Greely, professeur de droit à l’Université de Stanford et Kira Peikoff évoquent l’hypothèse d’un processus de gametogenèse in vitro, dans une publication du think-Tank The Hastings Center, aux Etats-Unis. La gametogenèse in vitro, fabrication de gamètes en laboratoire à partir de cellules souches pluripotentes induites, elles-mêmes issues de cellules “ordinaires” – de peau par exemple – deviendrait une hypothèse “plausible”.

Définitions:

• Gamètes :  cellules reproductrices, spermatozoïde chez l’homme et ovule chez la femme, qui  s’unissent au gamète de sexe opposé lors de la fécondation.
• Cellules souches pluripotentes induites, découvertes en 2006  : “ the Japanese researcher Shinya Yamanaka showed mouse skin cells could be made into Pluripotent Stem Cells, through a process known as ‘re-programming’. These cells resembled embryonic stem cells and were dubbed adult derived induced pluripotent stem cells (iPSC). These cells, like embryonic stem cells, have the potential to form all cell types of the body, including eggs and sperm. The generation of induced pluriportent stem cells was revolutionary to the stem cell field and medicine as a whole and was awarded the Nobel Prize in 2012 only 5 years after they were successfully made from human cells. Induced pluripotent stem cells have now been made from many cell types in addition to skin – including blood, hair follicles and cells from urine!” https://www.eurostemcell.org/fr/reproduction-and-fertility-how-could-stem-cells-help
