| Sumario: | Christian Drapeau,1 Kathleen F Benson,2 Gitte S Jensen2 1Biomx Stemceuticals, Austin, TX 78765, USA; 2NIS Labs, Klamath Falls, OR 97601, USA Purpose: The aim of this study was to evaluate the effects of a proanthocyanidin-rich extract of sea buckthorn berry (SBB-PE) on the numbers of various types of adult stem cells in the blood circulation of healthy human subjects. Study design and methods: A randomized, double-blind, placebo-controlled, cross-over trial was conducted in 12 healthy subjects. Blood samples were taken immediately before and at 1 and 2 hours after consuming either placebo or 500 mg SBB-PE. Whole blood was used for immunophenotyping and flow cytometry to quantify the numbers of CD45dim CD34+ CD309+ and CD45dim CD34+ CD309- stem cells, CD45- CD31+ CD309+ endothelial stem cells, and CD45- CD90+ mesenchymal stem cells. Results: Consumption of SBB-PE was associated with a rapid and highly selective mobilization of CD45dim CD34+ CD309- progenitor stem cells, CD45- CD31+ CD309+ endothelial stem cells, and CD45- CD90+ lymphocytoid mesenchymal stem cells. In contrast, only minor effects were seen for CD45dim CD34+ CD309+ pluripotential stem cells. Conclusion: Consumption of SBB-PE resulted in selective mobilization of stem cell types involved in regenerative and reparative functions. These data may contribute to the understanding of the traditional uses of SBB for preventive health, regenerative health, and postponing the aging process.
