Engineered cells with 'built-in genetic circuit' prevent tumour growth

Engineered cells with 'built-in genetic circuit' prevent tumour growth
Researchers at the University of Southampton have engineered cells with a 'built-in genetic circuit' that produces a molecule that inhibits the ability of tumours to survive and grow in their low oxygen environment. The genetic circuit produces the machinery necessary for the production of a compound that inhibits a protein which has a significant and critical role in the growth and survival of cancer cells. This results in the cancer cells being unable to survive in the low oxygen, low nutrient tumour micro-environment.

Pluripotent stem cells grow human intestines in a lab

Pluripotent stem cells grow human intestines in a lab
Scientists report in Nature Medicine using human pluripotent stem cells to grow human intestinal tissues that have functioning nerves in a laboratory, and then using these to recreate and study a severe intestinal nerve disorder called Hirschsprung's disease. The findings describe an unprecedented approach to engineer and study tissues in the intestine - the body's largest immune organ, its food processor and main interface with the outside world.

Scientists create blood from skin cells

Researchers in Singapore have artificially generated new mouse blood and immune cells from skin cells. This is a significant first step towards the eventual goal: the engineering of new human blood cells from skin cells or other artificial sources. One of the major challenges of regenerative medicine is to manufacture new blood and immune cells for patients in need.

Engineers make nanoscale 'muscles' powered by DNA

Engineers make nanoscale 'muscles' powered by DNA
The base pairs found in DNA are key to its ability to store protein-coding information, but they also give the molecule useful structural properties. Getting two complementary strands of DNA to zip up into a double helix can serve as the basis of intricate physical mechanisms that can push and pull molecular-scale devices. Engineers at the University of Pennsylvania have developed nanoscale "muscles" that work on this principle.

3D imaging technique maps migration of DNA-carrying material

3D imaging technique maps migration of DNA-carrying material
Scientists have mapped the reorganisation of genetic material that takes place when a stem cell matures into a nerve cell. Detailed 3D visualisations show an unexpected connectivity in the genetic material in a cell's nucleus, and provide a new understanding of a cell's evolving architecture. These unique 3D reconstructions of mouse olfactory cells, which govern the sense of smell, were obtained using X-ray imaging tools at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab).

Synthetic cells can isolate genetic circuits

Synthetic cells can isolate genetic circuits
Synthetic biology allows scientists to design genetic circuits that can be placed in cells, giving them new functions such as producing drugs or other useful molecules. However, as these circuits become more complex, the genetic components can interfere with each other, making it difficult to achieve more complicated functions. MIT researchers have now demonstrated that these circuits can be isolated within individual synthetic “cells,” preventing them from disrupting each other.

C dots can induce cell death in tumours

C dots can induce cell death in tumours
Nanoparticles known as Cornell dots, or C dots, have shown great promise as a therapeutic tool in the detection and treatment of cancer. Now, the ultrasmall particles – developed more than a dozen years ago by Ulrich Wiesner, the Spencer T. Olin Professor of Engineering – have shown they can do something even better: kill cancer cells without attaching a cytotoxic drug.

Stem cell ‘heart patch’ moves closer to clinic

The promise of stem cells to treat cardiovascular disease may soon be a step closer to clinical application as scientists from three institutions seek to perfect and test three-dimensional “heart patches” in a large animal model. In theory, the heart patches, engineered tissue composed of the several different types of cells that make up heart muscle, would be implanted to replace diseased or damaged tissue and would perform all the functions of healthy, beating heart muscle.

Stem cells grown into 3D lung-in-a-dish

Stem cells grown into 3D lung-in-a-dish
By coating tiny gel beads with lung-derived stem cells and then allowing them to self-assemble into the shapes of the air sacs found in human lungs, researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have succeeded in creating 3D lung "organoids." The laboratory-grown lung-like tissue can be used to study diseases including idiopathic pulmonary fibrosis, which has traditionally been difficult to study using conventional methods.

DNA-altering technology tackles diseases

DNA-altering technology tackles diseases
Researchers in Singapore have developed a protein that can alter DNA in living cells with much higher precision than current methods. The ability to alter DNA accurately will open more doors in the development of personalised medicine that could help to tackle human diseases that currently have few treatment options. Examples of diseases that have unmet therapeutic needs include neurodegenerative diseases like Huntington's disease, muscular dystrophies, and blood disorders like sickle cell anaemia.
