A young woman had gone through a painful divorce. She had lost her job. Her child had suffered injury in an accident. Then she was diagnosed with a severe illness. She asked her minister, referring to God, “Could you please ask him to get off my back?” Sometimes, when one setback piles up on another, people start to feel that they are being punished. They wonder how life can be so cruel. Faith starts to crumble and hope ebbs away. Some even admit “I’ve lost all hope”.

Brain Cells hope for sufferers …

British scientists are claiming to have made a major breakthrough after creating brain tissue from human skin.

(The cerebral cortex is the part of the brain that is responsible for most of the major high-level thought processes such as memory, language and consciousness.)

The researchers have for the first time generated crucial types of human brain cells in the laboratory by reprogramming skin cells, which they say could speed up the hunt for new treatments for conditions such as Alzheimer’s disease, epilepsy and stroke.

Until now it has only been possible to generate tissue from the cerebral cortex, the area of the brain where most major neurological diseases occur, by using controversial embryonic stem cells, obtained by the destruction of an embryo.

This has meant the supply of brain tissue available for research has been limited due to the ethical concerns around embryonic stem cells and shortages in their availability.

Scientists at the University of Cambridge, however, now insist they have overcome this problem after showing for the first time that it is possible to re-programme adult human skin cells so that they develop into neurons found in the cerebral cortex.

Initially brain cells grown in this way could be used to help researchers gain a better understanding of how the brain develops, what goes wrong when it is affected by disease and it could also be used for screening new drug treatments.

Eventually they hope the cells could also be used to provide healthy tissue that can be implanted into patients to treat neurodegenerative diseases and brain damage.

DrRickLivesey, who led the research at theUniversityofCambridge’s Gurdon [corr] Institute, said: “The cerebral cortex makes up 75% of the human brain, is where all the important processes that make us human take place. It is, however, also the major place where disease can occur.

“We have been able to take reprogrammed skin cells so they develop into brain stem cells and then essentially replay brain development in the laboratory.

“We can study brain development and what goes wrong when it is affected by disease in a way we haven’t been able to before. We see it as a major breakthrough in what will now be possible.”

The cerebral cortex is the part of the brain that is responsible for most of the major high-level thought processes such as memory, language and consciousness.

While human brain cells have been created from stem cells before, this has relied upon embryonic stem cells. Attempts to make them from skin cells have produced neurons that are not found in the cerebral cortex.

DrLiveseyand his colleagues were able to create the two major types of neuron that form the cerebral cortex from reprogrammed skin cells and show that they were identical to those created from the more controversial embryonic stem cells.

DrLivesey, whose findings are published in the journal Nature Neuroscience, said this may eventually lead to new treatments for patients where damaged tissue could be replaced by brain cells grown in the laboratory from a sample of their skin.

He said: “You don’t need to rebuild damage to recover function as the brain is quite good at recovering itself – it does this after stroke for example. However, it may be possible to give it some extra real estate that it can use to do this.

“We can make large numbers of cerebral cortex neurons by taking a sample of skin from anybody, so in principal it should be possible to put these back into the patients.”

DrSimonRidley, head of research at Alzheimer’s ResearchUK, which funded the study alongside theWellcomeTrust, added: “Turning stem cells into networks of fully functional nerve cells in the lab holds great promise for unravelling complex brain diseases such as Alzheimer’s.”

Where is Your Hope?

“Be strong and take courage, all you whose hope is in the Lord”.  Ps 31:24 NEB

It isn’t easy to be hopeful in today’s world. Almost every day we hear of terrorist groups letting off bombs somewhere in the world. Revolts, crime and theft on a massive scale abound. Bribery is rife. Evil rulers exploit the poor and the weak. In this situation some people give up hoping that things will ever get better. They give in to despair and ask, “What’s the point?”

Following  harrowing experiences you might well succumb to despair as well. But don’t. Out of pain you emerge purified, strengthened and deepened. And look forward in hope. Your future is in your hands. Trust in your own strength and powers from now.

Whether you give in to despair or live in hope will make a huge difference. In fact if you decide to hope, that alone will give you some of the strength and the courage that you need to survive in this evil world. Hope gives you the positive attitude that you need to face and overcome setbacks, disappointments, failures, conflicts, hardship and illness. Rev yourself up with hope  and look forward to the future.
