You quote a second hand source and I quote the collogen biochemist that did the research and he claims to have extracted “bone cells and blood vessels”. So you and your second hand sources know better then the Chief of the Division of Matrix Biology at Beth Israel Deaconess Medical Center that did the research.
“The results confirmed the existence of protein. “Because I am a collagen biochemist, our lab was contacted to perform an independent analysis of this new bone find,” explains Kalluri, who is Chief of the Division of Matrix Biology at BIDMC. “We isolated the proteins – collagen, laminin and elastin – from the bone, and also extracted bone cells and blood vessels from this sample. Our findings demonstrated that it did contain basement membrane matrix.”
“You quote a second hand source and I quote the collogen biochemist that did the research and he claims to have extracted “bone cells and blood vessels”.”
Ridiculous. My source was linked directly from the research institution that performed the analysis.
You quote a biochemist that did an independent review. And you quote him out of context of the analysis performed.
Don’t you ever get tired of making stuff up?
