--- Artificial womb could allow babies to develop outside the mother’s uterus.

Artificial wombs: medical miracle, legal nightmare.


The fact that the development of the artificial uterus is nearing completion is a mixed blessing. It will provide numerous benefits within the field of pediatric medicine, such as ensuring normal development to term of extremely premature foetuses, but it will pose numerous problems which the law is ill-equipped to handle. The legislature will have to examine the current definition of 'parent' which is based on normal conception practices. It will also have to determine whether only married couples should have access to this technology and under which conditions.


Germline stem cells that produce oocytes in vitro and fertilization-competent eggs in vivo have been identified in and isolated from adult mouse ovaries. Here we describe and validate a fluorescence-activated cell sorting-based protocol that can be used with adult mouse ovaries and human ovarian cortical tissue to purify rare mitotically active cells that have a gene expression profile that is consistent with primitive germ cells. Once established in vitro, these cells can be expanded for months and can spontaneously generate 35- to 50-μm oocytes, as determined by morphology, gene expression and haploid (1n) status. Injection of the human germline cells, engineered to stably express GFP, into human ovarian cortical biopsies leads to formation of follicles containing GFP-positive oocytes 1–2 weeks after xenotransplantation into immunodeficient female mice. Thus, ovaries of reproductive-age women, similar to adult mice, possess rare mitotically active germ cells that can be propagated in vitro as well as generate oocytes in vitro andin vivo.
