Internalized TF is degraded primarily in lysosomes. Pericytes were treated with MG132 or chloroquine prior to PMA for the indicated times. The mean + SD of 3 independent experiments is shown. **p<0.01, ***p<0.001. A. Relative amounts of internalized TF and expression of total TF were assessed by biotin labeling of cell surface proteins and western blotting as in “Methods”. B. The amounts of internalized TF are expressed as percentages relative to the total amount of TF expressed on the cell surface. C. Relative amounts of total TF expressed by PMA-treated pericytes are shown as percentages of TF expressed by control cells. D. Pericytes were stained for TF (green), the lysosomal marker LAMP-1 (red), and nuclei (blue, DAPI). E. Co-localization of TF and LAMP-1 was determined by calculating Pearson’s Correlation Coefficient with Image J, Fiji Plugin.

PMA shortens the half-life of TF protein while leaving degradation of TF mRNA unaffected. The mean +/− standard deviation (SD) of 3 independent experiments is shown. **p<0.01, ***p<0.001. A. Pericytes were pre-treated with Cyclohexamide (CHX) prior to addition of vehicle or PMA for the indicated times. Degradation of TF protein was assessed by western blot. B. Relative amounts of TF protein expressed by CHX-treated cells are given as a percentage of TF expressed by non-CHX-treated control cells. C. Pericytes were pre-treated with Actinomycin D (ActD) prior to receiving vehicle or PMA for the indicated times. Degradation of TF mRNA was analyzed by qRT-PCR. The amount of TF mRNA expressed by ActD-treated pericytes relative to non-ActD-treated control cells is shown.

PMA increases internalization of TF from the pericyte surface. Where specified, pericytes were pre-treated with either Go 6983 or GFX prior to receiving PMA for the times indicated. The mean +SD of 3 independent experiments is shown. **p<0.01, ***p<0.001. A. Pericyte cultures were fixed and stained for TF (green). Prominent punctate staining for TF was seen 4 hours after PMA while TF was virtually absent 8 hours after PMA. B. The total TF content of pericytes was determined by western blotting of whole cell lysates. Internalized surface TF was determined by labeling cell surface proteins with biotin, isolating biotin-labeled proteins from cell lysates, and assessing their TF content by western blotting. C. Relative amounts of internalized TF are shown as a percentage of the total surface TF. D. Relative amounts of total TF are presented as a percentage of the total surface TF expressed by vehicle-treated control cells. E. Activity of surface TF was determined on whole cells by measuring the rate of FXa generation.
