Cells show increased proinflammatory factor and decreased hematopoietic factor gene expression and enhance KOBA cell proliferation at the cost of supporting normal hematopoiesis

OP9/L cells display elevated proinflammatory issue and reduced hematopoietic element gene expression and boost KOBA mobile proliferation at the value of supporting regular hematopoiesis. (a) OP9, OP9/L, and OP9/P cells have been analyzed for the expression of indicated cytokine genes with quantitative RT-PCR. The means and SEs of triplicate determination are revealed. P Most pancreatic injuries in China are due to blunt abdominal trauma, such as motor vehicle crashes, falls, bicycle handlebar injuries hematopoiesis, such as Scf, Cxcl12, and Angpt1, was significantly decreased (Fig 4A). Again, the effects were specific for KOBA cells, and OP9/P cells barely showed such changes, except for a rather increased Angpt1 expression. We confirmed that OP9/L cells secreted significantly more Ccl5 and OPN and much less Cxcl12 and Scf than OP9 cells (Fig 4B). The altered cytokine pattern was unaffected by DAPT and was apparently independent of Notch activation (Fig 4B). Further, unlike the Cdkn repression via Notch activation, the effects on cytokine genes lasted longer, for at least 3 days after the depletion of KOBA cells with imatinib (S3B Fig). OP9/L cells showed significantly increased expression of a series of genes related to adipocyte differentiation including Cebpb and adipokines (S4 Fig) and thus, the diverse effects on cytokine expression may be partly associated with adipocytic differentiation of OP9 cells.
