She said that in the last few decades, biomedical engineers have been trying to make blood stem cells in laboratory dishes to solve the problem of donor blood stem cell shortages. (scitechdaily.com)
Though ostensibly developed to facilitate reproduction in individuals for whom this capability is impaired or unavailable, the use of laboratory produced eggs and sperm represent an opening for the routine production and commercialization of "designer babies. (independentsciencenews.org)
