Fertile eggs created from mouse stem cells – Expert Reaction

Sarah-Jane O'Connor posted in on October 18th, 2016.

Japanese researchers have successfully produced functional mouse eggs entirely in cell culture using stem cells. Their study, published today in Nature, resulted in healthy and fertile mouse pups. The researchers say being able to grow viable mouse eggs in the lab will provide clues to aid the development of similar systems in other species. More information […]

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 […]

Human embryo gene editing gets UK go-ahead – Expert reaction

John Kerr posted in on February 2nd, 2016.

A regulatory body in the UK  has approved the first research application to use new ‘gene editing’ techniques on human embryos. The Human Fertilisation and Embryology Authority is the UK’s independent regulator overseeing the use of gametes and embryos in fertility treatment and research. The Authority has today approved a proposal for new research, led by […]

A simpler way to make stem cells? Experts respond

Peter Griffin posted in on January 30th, 2014.

Researchers in the US and Japan have developed a revolutionary new technique for creating pluripotent stem cells by exposing mature cells to environmental stress. The process could be faster and cheaper than existing methods that require manipulation of genes inside a cell’s nucleus. Our colleagues from the UK SMC rounded up comment from UK-based experts. […]

Stem cells induced in living mice – experts respond

John Kerr posted in on September 12th, 2013.

Scientists have reprogrammed adult cells to revert to a stem cell state inside living mice. Induced pluripotent stem cells, which have the potential to differentiate into many mature cell types, have been generated in Petri dishes in the lab, but never before in a living animal. Now, Spanish researchers have shown that the with the […]

World’s first cultured beef burger – experts respond

John Kerr posted in on August 6th, 2013.

In a world first, Professor Mark Post of Maastricht University has revealed a Cultured Beef burger in London today. The burger, which was cooked by frying in a pan, was presented at a live event in front of a audience of some 200 journalists and academics. You can watch a recording of the full event […]

Human liver tissue grown in mice – experts respond

John Kerr posted in on July 4th, 2013.

Japanese scientists have grown functional human liver  tissue –  in mice. The working  human liver made using induced pluripotent stem cells was described in Nature this week. The liver is generated by transplanting liver buds (created in the laboratory) into mice, where the buds mature into tissue resembling the adult liver. Although it remains to […]

Errors noted in stem cell ‘breakthrough’ research – Nature News

John Kerr posted in on May 24th, 2013.

Nature News reports on new developments regarding the stem cell breakthrough published last week: several errors have been noted in the article and critics are unimpressed with incredibly short peer review process. An excerpt (read in full here): Stem-cell cloner acknowledges errors in groundbreaking paper Critics raise questions about rush to publication. A blockbuster paper […]

Human stem cell lines created through “therapeutic cloning” – experts respond

John Kerr posted in on May 16th, 2013.

Scientists have successfully reprogrammed human skin cells to become embryonic stem cells capable of transforming into any other cell type in the body. It is believed that stem cell therapies hold the promise of replacing cells damaged through injury or illness. While scientists have previously been able to make embryonic stem cells using this approach […]
