Scientists in Cambridge and London have developed a catalogue of DNA mutation ‘fingerprints’ that could help doctors pinpoint the environmental culprit responsible for a patient’s tumour – including showing some of the fingerprints left in lung tumours by specific chemicals found in tobacco smoke.
Researchers say that new ‘mini-placentas’ – a cellular model of the early stages of the placenta – could provide a window into early pregnancy and help transform our understanding of reproductive disorders. Details of this new research are published today in the journal Nature.
Would you eat a burger that had been grown in a lab? It may not be long before this is a choice at your local supermarket. Given the environmental cost of rearing cattle for meat, this is a development that cannot come soon enough.
A team of scientists at the University of Cambridge has developed an artificial mouse embryo-like structure capable of forming the three major axes of the body. The technique, reported today in the journal Nature, could reduce the use of mammalian embryos in research.
The creation of artificial embryos has moved a step forward after an international team of researchers used mouse stem cells to produce artificial embryo-like structures capable of ‘gastrulation’, a key step in the life of any embryo.
Almost 30 years on from the discovery of the genetic defect that causes cystic fibrosis, treatment options are still limited and growing antibiotic resistance presents a grave threat. Now, a team of researchers from across Cambridge, in a major new centre supported by the Cystic Fibrosis Trust, hopes to turn fortunes around.
The past few years has seen an explosion in the number of studies using organoids – so-called ‘mini organs’. While they can help scientists understand human biology and disease, some in the field have questioned their usefulness. But as the field matures, we could see their increasing use in personalised and regenerative medicine.
Scientists have shown in mice that skin cells re-programmed into brain stem cells, transplanted into the central nervous system, help reduce inflammation and may be able to help repair damage caused by multiple sclerosis (MS).
Scientists have created mini biological models of human primary liver cancers, known as organoids, in the lab for the first time. In a paper published in Nature Medicine, the tiny laboratory models of tumours were used to identify a new drug that could potentially treat certain types of liver cancer.
