Thank you, daouda. Catechin looks especially interesting.
However if you give credit to that study it tells you that the best bang for your buck is probably combining a green tea extract high in catechins + vit D3 + carnosine + a blueberry extract, since the synergy between this coumpounds gives more stem cell proliferation than the sum of their separate effects. I dont know what exactly is that "catechin" talken about in this study, apparently it is a extract from green tea made by "sigma" (found this
http://www.sigmaaldr...ng=fr®ion=FR) but it's a little confusing since it is favorably compared to EGCG (a green tea catechin) and green tea extracts (rich in catechins) for its stem cell proliferating properties.
I personally take NOW foods "EGCG green tea extract" for my stem cell combo
It is said to contain
"min. 98% Total Polyphenols, 80% Total Catechins, and 50% EGCg (Epigallocatechin Gallate) (200 mg)"so 30% of catechins which arent EGCG, amongst which is certainly found the interesting "catechin" compound per the study cited above (i made a mistake talking about "polyphenols" in that sentence you quoted above, I should have written "catechins")
Relevant extract (sorry for the redundance but its probably better shown more complete
Several whole food extracts, herbal extracts, and specific compounds were screened individually for proliferative activity on human bone marrow cells in culture.
Spinach, spirulina, EGCG, epicatechin, withania, somnifera, carao, rehmania glutinosa, and astragulus membranoceaus did not show high activity on proliferation of human bone marrow cells in culture and were not tested further.
Certain whole-food extracts, such as blueberry, green tea, and specific compounds, including catechin, carnosine, and vitamin D3, were found to increase cell proliferation of human bone marrow cells in a dose-dependent manner
A little article to clarify between polyphenols, catechins and EGCG
