Cryopreserved embryos in Argentina: more than 12,000

In Argentina, more than 12,000 “abandonded” embryos (created upon request of an infertile couple but never implanted) are stoed and frozen in crypresearvation facilities and there is no plan for them to be used in assisted reproduction treatment or in research. This is the result of two decades of embryo cryopreservation. In some cases, ambryos

Abnormalities in human pluripotent cells due to reprogramming mechanisms

Researchers from Oregon Health & Science University show that, when pluripotent stem cells (iPSCs) or stem cells created using a process called somatic cell nuclear transfer (SCNT) are compared, the genomic and epigenomic landscapes of the resulting cell types differ with the genomes of stem cells created through SCNT matching those of embryonic stem cells
