These cells lay down collagen (connective-tissue protein) composed of tough, durable fibrils (minute fibres), and, eventually, scar formation ensues. 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. Because it is resized when the size of a picture is changed, it is useful with digital images. As dermal fibroblasts are the major MMP-producing cells in the dermis, reduction of dermal fibroblast size, which is observed in aged human skin, contributes to the elevation of age-related multiple MMPs. Bundles of actin filaments occur in the cytoskeletons of cells such as fibroblasts (mouse embryo fibroblasts shown; cells were stained with a green fluorescent-tagged peptide called phalloidin).
