TLR-induced production of hematopoietic growth factors by B cells. Purified B cells were stimulated as in Fig. 1. Supernatants were collected and examined for the production of G-CSF and GM-CSF by multiplex biomarker immunoassay. Both G-CSF and GM-CSF were produced predominantly in response to TLR1/TLR2 agonist
