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.
Nanobots that patrol our bodies, killer immune cells hunting and destroying cancer cells, biological scissors that cut out defective genes: these are just some of technologies that Cambridge researchers are developing which are set to revolutionise medicine in the future.
In the centenary year of the publication of a seminal treatise on the physical and mathematical principles underpinning nature – On Growth and Form by D’Arcy Wentworth Thompson – a Cambridge physicist has led a study describing an elegantly simple solution to a puzzle that has taxed biologists for centuries: how complex branching patterns of tissues arise.
Artificial bile ducts grown in lab and transplanted into mice could help treat liver disease in children03 Jul 2017
Cambridge scientists have developed a new method for growing and transplanting artificial bile ducts that could in future be used to help treat liver disease in children, reducing the need for liver transplantation.
It is almost impossible for an injured heart to fully mend itself. Within minutes of being deprived of oxygen – as happens during a heart attack when arteries to the heart are blocked – the heart’s muscle cells start to die. Sanjay Sinha wants to mend these hearts so that they work again.
Scientists have shown how the precursors of egg and sperm cells – the cells that are key to the preservation of a species – arise in the early embryo by studying pig embryos alongside human stem cells.
