Hi farviewhill,

In my opinion NBS is taking a methodical approach in their response to yesterday's article questioning their VSELs.
Robin Smith is a pretty smart woman and that's why she is sitting in that CEO position.
We can probably expect a response from her very soon.


"Earlier this year, NeoStem announced plans to launch the first human trials of the cells for bone growth.
“We tried as hard as we could to replicate the original published results using the methods described and were unable to detect these cells in either the bone marrow or the blood of laboratory mice,” said lead author Irving Weissman, who directs Stanford’s Institute for Stem Cell Biology and Regenerative Medicine.
Weissman’s study is the first to evaluate the biological potency of the cells, and it found they could not transform into blood cells and contained very little DNA.
Instead, researchers found that what purported to be VSELs — about five micrometers in diameter — were either debris or dead cells.
“A true pluripotent cell would be able to differentiate into any tissue type,” said Weissman. “But we couldn’t confirm that cells of that size or phenotype could generate hematopoietic cells with any reliability.”
In response, NeoStem chairman and CEO Robin Smith said the company has studies in progress that will “confirm whether or not VSEL(s) have characteristics of a pluripotent stem cell.”

I agree with you, it's a pretty hard blow to their VSELs...for now.
