    COX-2 and NeuN double stains 24 hours and one week after tMCAo . The COX-2 IHC was developed with nickel-enhanced DAB (black), whereas NeuN was visualized with NovaRed ® (brownish red). The images 5A and 5B are obtained from a pilot study where the animal was euthanized 24 hours after tMCAo. 5A visualizes a relatively small neocortical infarct in the right hemisphere. The box delineates a part of the ischemic border zone that is shown at forty times magnification in 5B . The penumbra contains large swollen neurons that express the membrane-bound COX-2 enzyme. In the infarct core the neurons tend to be small and star-shaped due to irreversible neuronal death. 5C and 5E are from a saline-treated animal one week after tMCAo. Forty times magnifications of the boxes are shown in 5D and 5F . The neurons in the border zone on Day 8 after ischemic injury showed a perinuclear expression pattern of the COX-2 enzyme ( 5D ). COX-2 + neurons can be found in areas like the neocortex, piriform cortex and the DG of the hippocampus under normal conditions. 5F shows COX-2 expressed in dendrites of neurons in the molecular cell layer of the DG. The scale bar in 5A is 5 mm, whereas the scale bars in 5B , 5D and 5F equals 50 μm.

    BrdU, ED-1 and NeuN stains one week after tMCAo . 9A to 9F show the IHC for BrdU and ED-1. BrdU was developed with nickel-enhanced DAB (black), whereas the activated microglia marker ED-1 was visualized with NovaRed ® (brownish red). 9A shows a representative example of a tMCAo animal one week after surgery. Four and forty time magnifications of the boxes in 9A and 9B are shown in 9B and 9C , respectively. The BrdU + cells are typically found in clusters in the subgranular cell layer in DG. Our counting procedure started with delineating the DG. Hereafter, the BrdU + cells in the whole DG were counted at forty times magnification ( 9C ). We generally observed a very scarce ED-1 expression in the DG unless the hippocampus was directly affected by ischemic injury. 9D to 9I show an example of ischemia affecting the right hippocampus. The boxed area in 9D is shown at higher magnification in 9E . Activated microglia was abundantly seen in a part of the CA-1 and the whole DG. 9F shows a forty time magnification of the box in 9E . Clearly, activated microglia had an intimate relation to an increasing number of BrdU + cells. Panel 9G to 9I show NeuN IHC developed with nickel-enhanced DAB. 9G and 9H correspond to 9D and 9E . The boxed area in 9H of the CA-1 is shown at forty time magnification in 9I . Note the ischemic degeneration of this part of the CA-1. The scale bar in 9A is 5 mm. In 9B the scale bar represents 300 mm, and in 9E and 9H 1 mm. The scale bars in 9C , 9F and 9I equals 50 μm.

    Localisation of uPAR and CD68-positive macrophages in colorectal liver metastases. Adjacent sections from a liver metastasis with desmoplastic growth (a)–(c), a liver metastasis with pushing growth pattern (d)–(f), and a liver metastasis with replacement growth pattern (g)–(i) were stained for uPAR (a), (b), (d), (e), (g), (h) or double stained for cytokeratin and CD68 (c), (f), (i). The uPAR-immunoreactivity was visualised by NovaRed, cytokeratin with Permanent Red, and CD68 with DAB. In the liver metastasis with desmoplastic growth pattern, strong expression of uPAR is seen in macrophages located at the invasive front within the desmoplastic zone (a), (b). Large numbers of macrophages were found at the front of the metastasis (c). In the liver metastasis with pushing growth pattern, uPAR expression is seen in a few macrophages and fibroblast-like cells intermingled with the tumour cells (d), (e). Few macrophages are located at the metastasis/liver parenchyma interface (f). In the liver metastasis with replacement growth pattern, uPAR expression is confined to some macrophages and fibroblast-like cells located between the tumour cells (g)-(h). Few macrophages are located at the metastasis/liver parenchyma interface (i). Black arrows points at the tumour periphery. Black arrowhead in (e) and (g) points at a uPAR-positive neutrophil, which is an internal positive control. Bar a: 100 μ m. Bar b: 50 μ m.

    Immunophenotyping and growth characteristics of 12E2 cells in footpad microinjection model at 1 week. A and B: Microinjection of control medium containing inert carbon failed to influence number or distribution of constitutive FXIIIaDD. C , D , and D inset : In contrast, syngeneic footpads microinjected with 12E2 cells produced a lesion composed of closely-aggregated FXIIIaDD. E: CFSE prelabeling of 12E2 cells before injection and detected immunohistochemically demonstrated that the experimentally introduced 12E2 cells, and not recipient (constitutive) FXIIIaDD, accounted for this lesion. CFSE label was of variable intensity within 12E2 cells, consistent with dilution consequent to proliferation ( E , inset ). F: The in situ growth pattern of 12E2 cells was characterized by interstitial permeation between collagen and smooth muscle fibers by conventional H E staining. G and H: Immunohistochemistry (here for CFSE) permitted detection of envelopment of dermal blood vessels ( G ) and nerves ( H ) by infiltrating 12E2 cells. This pattern differed from that of microinjected 3T3 fibroblasts, which failed to exhibit infiltrative growth. Similar findings were documented in footpads from SCID and allogeneic (CBA) mice, although the latter was associated with a brisk mononuclear cell infiltrate. Arrows indicate particulate carbon deposits ( A and B ). m, smooth muscle fiber ( F ); v, vessel ( G ); n, nerve fiber ( H ).

C to F: Immunohistochemistry of adjacent sections of 12E2 microinjection site (1 week) stained for FXIIIa ( C and E ) and the endothelial marker, CD31 ( D and F ), documenting angiogenesis associated with infiltration of 12E2 cells. G and H: Conventional histology of characteristic human KS lesion. I to L: Immunohistochemistry of adjacent sections of typical human KS lesion stained for FXIIIa ( I and K ) and CD31 ( J and L ). Note histological and immunohistochemical similarities to the 12E2 microinjection sites ( A to F ). *Corresponding adjacent foci in C to F , I and J , K , and L FXIIIa/CD31 pairs. Original magnifications: ×400 ( A , E to G , K , and L ) and ×200 ( B to D , H to J ). H E staining in A , B , G and H . NovaRed chromagen in C to F and I to L .

    Recombinant IFN-γ-induced Ia expression and allostimulatory activity by 12E2 cells in vitro . A to C: 12E2 cells were negative to weakly positive by immunohistochemistry for Ia ( A ), whereas exposure to increasing concentrations of recombinant IFN-γ induced progressively intense immunoreactivity ( B and C ). D: Fixed numbers of naïve B10.BR T cells were combined with decreasing numbers of the respective stimulator cell type (BALB/c-positive control splenocytes (□), unstimulated 12E2 cells (○), 12E2 cells with IFN-γ pretreatment (▪), and IFN-γ-pretreated 3T3-negative control murine fibroblasts (•) to attain the indicated stimulator:responder ratios. Proliferation was measured on day 4 of co-culture and the stimulation index (SI) was calculated (see Materials and Methods). Optimal BALB/c allogeneic control stimulation at higher stimulator:responder cell ratios is shown. However, correlative data could not be generated for 12E2 cells as a result of cell aggregation at these higher ratios. Original magnification, ×400 with NovaRed chromagen ( A to C ).
