Stem Cells to Brain Cells?!

Lets talk about weird cloning in the Dolly world....
Hell that didn't even make sense to me! So lets se if I can unravel it a bit.

Scientists at the Centre for Regenerative Medicine were able to make brain cells using stem cells from people suffering from schizophrenia, bipolar disorder and other mental illnesses. Why? To study the neurons and specifically to look at standard psychological medicines, such as lithium, to see how they affect these cells in the laboratory.

It seems that many of the drugs used to treat mental illness are well documented as to their effication but little is truly known as to how the drugs actually affects the brain cells of the patient.

The article goes on to say

• Scientists also hope to work on multiple sclerosis, Parkinson's disease and motor neuron disease.

Now scientists create a sheep that's 15% human

Scientists have created the world's first human-sheep chimera - which has the body of a sheep and half-human organs.

The sheep have 15 per cent human cells and 85 per cent animal cells - and their evolution brings the prospect of animal organs being transplanted into humans one step closer.

Professor Esmail Zanjani, of the University of Nevada, has spent seven years and £5million perfecting the technique, which involves injecting adult human cells into a sheep's foetus.

He has already created a sheep liver which has a large proportion of human cells and eventually hopes to precisely match a sheep to a transplant patient, using their own stem cells to create their own flock of sheep.

Inkjet printing with live stem cells: "bio-inks"

Researchers at Carnegie Mellon University and the University of Pittsburgh have successfully directed adult stem cells from mice to develop into bone and muscle cells with the aid of a custom-designed ink-jet printer and the use of "bio-inks." These inks consist of anything from proteins to individual cells printed in microscopic patterns. By printing layer upon layer of cell patterns, scientists may one day be able to "print" whole tissues or organs for replacement therapies.
