    Summary
    exogenous Tβ4 also increased IL-8 secretion and blocking of IL-8 with neutralizing antibodies decreased Tβ4-induced ASC proliferation, suggesting that IL-8 is a critical mediator of Tβ4-enhanced proliferation.
  4. 04LabIn vitro (cells)Mechanism

    In human adipose-derived stem cells, neutralizing antibodies against IL-8 decreased the Tβ4-induced proliferation.

    In plain wordsIn cells, blocking IL-8 reduced the extra growth that Tβ4 caused in human fat-derived stem cells.
