2 Fig. 1 Photomicrograph of microvascular environment demonstrates a central capillary surrounded by a mast cell (MC), fibroblast (F), and a macrophage (MP). Original magnification, 4300×.

3 Fig. 2 Presence of a well-developed perivascular cuff (PC) in a patient with class 6 CVI. Lymphatic vessel is at edge of perivascular cuff. Long arrow points at macrophage that appears to be entering lymphatic lumen (LL). Cell near this macrophage is a fibroblast. Short arrow indicates pericuff macrophage. F denotes a pericuff fibroblast. Original magnification, 4300×.

4 Fig. 3 Section through an endothelial cell in a patient with class 4 CVI. Nucleus presents a euchromatic (EU) appearance and a prominent nucleolus (long arrow). Note abundance of ribosomes (short arrows) in the cytoplasm. Original magnification, 18,125×.

5 Fig. 4 Section through an endothelial cell in a patient with class 4 CVI. Note abundance of ribosomes (short arrows). Some ribosomes are free in the cytoplasm, whereas others are attached to endoplasmic reticulum. Original magnification, 18,125×.

6 Fig. 5 Section through a capillary in a patient with class 6 CVI. Note collapsed capillary lumen. A well-developed perivascular cuff (PC) surrounds the capillary. Fibroblasts (F) and migrating tails of macrophages (arrows) from an envelope around perivascular cuff. Original magnification, 4300×.

7 Fig. 6 Demonstration of message for TGF-β1 in skin biopsy from a class 5 CVI patient. TGF-β1 mRNA by RT-PCR and electrophoresed in a 2% agarose gel. Note that TGF-β1 is present in biopsy from class 5 CVI patient (CVI lane) but is absent in normal skin biopsy (NS lane). Housekeeping gene glyceraldehyde-3-phosphate dehydrogenase (G3PDH) served as control for PCR amplification. Ladder lane serves as index of base pairs (molecular weight). NC, Negative control; PC, positive control. TGF-β1 mRNA denotes lanes in which TGF-β1 cDNA samples were loaded for electrophoresis.
