Replacement Heart Parts From Adult Stem Cells
The future of extremely long life for humans is less than 3-5 years away thanks to the miracle of adult stem cells (as opposed to the murder of human beings using embryonic stem cells). This breakthrough comes as scientists have been able to grow replacement heart valves from adult patient bone marrow cells:
Growing replacement tissue from stem cells is one of the principal goals of biology. If a damaged part of the body can be replaced by tissue that is genetically matched to the patient, there is no chance of rejection. So far, scientists have grown tendons, cartilages and bladders, but none of these has the complexity of organs, which are three-dimensional structures of dozens of different types of cells.
…
By using chemical and physical nudges, the scientists first coaxed stem cells extracted from bone marrow to grow into heart valve cells. By placing these cells into scaffolds made of collagen, Dr Chester and his colleague Patricia Taylor then grew small 3cm-wide discs of heart valve tissue. Later this year, that tissue will be implanted into animals – probably sheep or pigs – and monitored to see how well it works as part of a circulatory system.
If that trial works well, Prof Yacoub is optimistic that the replacement heart tissue, which can be grown into the shape of a human heart valve using specially-designed collagen scaffolds, could be used in patients within three to five years.
The snakeoil salesmen pushing the embryonic stem cell BS have been finally proven wrong – and way too late. In 3-5 years not a dime will need to go to killing young humans. Not a dime. There will be no fake promises left to make.
And embryonic stem cell projects depend on cell theft from the youngest human lives. Think Dr Frankenstein.
UK Scientists Grow Heart Tissue…
A British research team has grown part of a human heart from stem cells for the first time, the Guardian newspaper reported on Monday.
