A NEW CHIP COULD BE USED TO FIGHT ALZHEIMER'S ONE DAY !

A new chip reprograms our skin cells to help you heal faster. It affects the entire tissue not just the surface. Developed by researchers, this chip is placed on an injured body part and a small electrical current is applied, and are then programmed  to turn into vascular cells or whatever cells are needed for treatment, helping serious injuries heal within weeks. This chip showed promising results when tested on mice and pigs, which had injured legs lacking blood flow. The device could have other uses too. The technology is not just limited to skin. It can be used on other tissues within the body or  outside the body. Skin is only one example. The tech was even able to reprogram skin cells into nerve cells, helping mice recover from strokes. Researchers believe it could  one day be used to grow brain cells from human skin. Cells could then be harvested and injected in the brain, fighting diseases like Alzheimer's and Parkinson's. Clinical trials are expected to start next year.

New beating 3D heart tissue may improve cardiac treatment

Researchers have created a 3D heart tissue that beats in synchronised harmony, like a heart in love, that will lead to better understanding of cardiac health and improved treatments.

Researchers at York University in Canada have devised a way to stick three different types of cardiac cells together, like Velcro, to make heart tissue that beats as one.

Until now, most 2D and 3D in vitro tissue did not beat in harmony and required scaffolding for the cells to hold onto and grow, causing limitations.

In this research, Professor Muhammad Yousaf and his team from York University made a scaffold free beating tissue out of three cell types found in the heart - contractile cardiac muscle cells, connective tissue cells and vascular cells.

The researchers believe this is the first 3D in vitro cardiac tissue with three cell types that can beat together as one entity rather than at different intervals.

"This breakthrough will allow better and earlier drug testing, and potentially eliminate harmful or toxic medications sooner," said Yousaf.

In addition, the substance used to stick cells together (ViaGlue), will provide researchers with tools to create and test 3D in vitro cardiac tissue in their own labs to study heart disease and issues with transplantation.

"Making in vitro 3D cardiac tissue has long presented a challenge to scientists because of the high density of cells and muscularity of the heart," said Dmitry Rogozhnikov from York University.

"For 2D or 3D cardiac tissue to be functional it needs the same high cellular density and the cells must be in contact to facilitate synchronized beating," said Rogozhnikov.

Although the 3D cardiac tissue was created at a millimeter scale, larger versions could be made, said Yousaf, who has created a start-up company OrganoLinX to commercialize the ViaGlue reagent and to provide custom 3D tissues on demand.

The study was published in the journal Scientific Reports.
