What are the classifications of Primary Fibroblasts?

Question

Fibroblast is a type of cell that synthesizes extracellular matrix and collagen, which form the basic framework structure of biological connective tissue in animals and play an important role in tissue repair. As well as being present as fibroblasts, these cells exist in an alternative state, as fibrocytes. Fibroblast is the term used to describe these cells when they are in an activated state.
