Hypothesis

Can Garcinol, a histone acetyltransferase inhibitor, effectively expand human hematopoietic stem cells ex vivo?

Conclusion

Garcinol significantly increases the number of hematopoietic stem cells and progenitor cells in culture.

Supporting Evidence

  • Garcinol increased the number of CD34+CD38– HSCs/PCs more than 4.5-fold.
  • Isogarcinol, a derivative of Garcinol, expanded HSCs/PCs 7.4-fold.
  • Garcinol expanded the number of SCID-repopulating cells 2.5-fold.

Takeaway

Garcinol helps grow more blood stem cells from umbilical cord blood, which can be useful for treatments.

Methodology

The study screened 92 natural products for their ability to expand hematopoietic stem cells and found that Garcinol increased cell numbers significantly during a 7-day culture.

Participant Demographics

Human cord blood samples were used.
