Embryo research hits ethical barrier – Expert Reaction

John Kerr posted in on May 5th, 2016.

Scientists have broken through a technical barrier in human embryo research and now face an ethical one. Two separate studies published in Nature and Nature Cell Biology today report on new methods allowing human embryos to cultured and studied in Petri dishes for as long as 13 days. Previous studies have struggled to keep embryos […]

Sperm derived from stem cells – Experts reaction

John Kerr posted in on February 26th, 2016.

Scientists in China have created functioning sperm from mice stem cells in the laboratory. To accomplish this feat, the researchers coaxed mouse embryonic stem cells to turn into functional sperm-like cells, which were then injected into egg cells to produce fertile mouse offspring. The research, published in Cell Stem Cell, provides a platform for generating […]
