Research conducted by Derrick Rossi at Boston’s Children Hospital had a huge breakthrough. By programming an RNA messenger (mRNA) a certain way, they can safely insert genetic switches into a cell without changing the DNA with virus vectors! PhysOrg said that these induced pluripotent stem cells (iPSC) are “apparently identical to human embryonic stem cells, the initial building blocks of all the organs of the body.”
This solves not one major problem but all three problems since induced pluripotent stems were discovered back in 2007. Shinya Yamanaka deserves a Noble Prize for his discovery and the progress made by Rossi is simply, “awesome” and perhaps he too in the future deserves a Nobel Prize!
“Because the mRNA carries genetic instructions, but does not enter the DNA of the target cells, the resulting tailored cells should be safe to use in treating patients, Rossi said, unlike the iPS cells now being created around the world.
“Our findings address three major impediments to clinical translational use of iPS cells,” Rossi said in an interview. “The method: does not in any way breach genomic integrity as it does not necessitate integrating genes or viruses into the target cells’ DNA; it is orders of magnitude more efficient at producing iPS cells than conventional iPS methods, which were notoriously inefficient; and it gives us a way to directly program and direct the fate (development) of the iPS cells towards clinically useful cell types.”
This is not the only breakthrough happening in adult stem cell research, recently there were some researchers at the Royal Prince Alfred Hospital and the University of Sydney that “found a way to increase the number of blood-forming stem cells when growing them outside of the body.”
“By using a unique stretchy surface that allows the cells to pull on it, the researchers found they could generate up to three times more stem cells than using current methods alone. Published today in the leading biotechnology journal Nature Biotechnology, lead author Professor John Rasko from the Centenary Institute and RPA Hospital announced these findings could significantly improve the outcomes of stem cell transplants.”
Huge breakthrough here because the more that can be grown in the lab, the less they have to harvest from the body like umbilical cords, bone marrow, and other areas and thus, the more patients can benefit! On another breakthrough this time coming from the University of Buffalo, researchers have found a way to keep adult stem cells from aging!
In science daily…
“UB scientists created the new cell lines — named “MSC Universal” — by genetically altering mesenchymal stem cells, which are found in bone marrow and can differentiate into cell types including bone, cartilage, muscle, fat, and beta-pancreatic islet cells. The researchers say the breakthrough overcomes a frustrating barrier to progress in the field of regenerative medicine: The difficulty of growing adult stem cells for clinical applications.”
This discovery could help speed up the development of cost-effective treatments for diseases including heart disease, diabetes, immune disorders and neurodegenerative diseases! Also, lowering costs of stem cell therapies and being able to produce individually-tailored cell lines. And finally this latest breakthrough adult stem cell research “electrified the field,” because of the new ability to reprogram adult stem cells to behave just like embryonic stem cells!
This is great science! A science who’s research is not getting more complex with fifty different explanations due to falsifications in the data that in itself is mere speculation while many of them cannot be tested nor verified. But in instead this research is producing a better understanding for the improvement of mankind!
