Biologically relevant, three-dimensional extracellular matrix is an essential
component of in vitro vasculogenesis models. WI-38 fibroblasts assemble a 3D
matrix that induces endothelial tubulogenesis, but this model is challenged by
fibroblast senescence and the inability to distinguish endothelial cell-derived
matrix from matrix made by WI-38 fibroblasts. Matrices produced by
hTERT-immortalized WI-38 recapitulated those produced by wild type fibroblasts.
ECM fibrils were heavily populated by tenascin-C, fibronectin, and type VI
collagen. Nearly half of the total type I collagen, but only a small fraction of
the type IV collagen, were incorporated into ECM. Stable hTERT-WI-38
transfectants expressing TagRFP-fibronectin incorporated TagRFP into ~90% of the
fibronectin in 3D matrices. TagRFP-fibronectin colocalized with tenascin-C and
with type I collagen in a pattern that was similar to that seen in matrices from
wild type WI-38. Human Umbilical Vein Endothelial Cells (HUVEC) formed 3D
adhesions and tubes on WI38-hTERT-TagRFP-FN-derived matrices, and the
TagRFP-fibronectin component of this new 3D human fibroblast matrix model
facilitated the demonstration of concentrated membrane type 1 metalloprotease and
new HUVEC FN and collagen type IV fibrils during EC tubulogenesis. These findings
indicate that WI-38-hTERT- and WI-38-hTERT-TagRFP-FN-derived matrices provide
platforms for the definition of new matrix assembly and remodeling events during
vasculogenesis.
