the principal nonmotile cells of connective tissue; fibroblasts are large, flat, elongated (spindle-shaped) cells possessing processes extending out from the ends of the cell body. The cell nucleus is flat and oval. Fibroblasts produce tropocollagen, which is the forerunner of collagen, and ground substance, an amorphous, gel-like matrix that fills the spaces between cells and fibres in connective tissue.
