After thawing from liquid nitrogen, there is clear morphology till one/two passages. Initially, it consists of a network of type-III collagen, a weaker form of the structural protein that can be produced rapidly. There is growing evidence that activated synovial fibroblasts, as part of a complex cellular network, play an important role in the pathogenesis of rheumatoid arthritis. The dermis is an integrated system of fibrous, filamentous, and amorphous connective tissue that accommodates several cells such as fibroblasts, monocytes/macrophages, mast cells, neutrophils and lymphocytes, nerve and vascular networks, and the appendages formed by the epidermis.

Secondary fibroblasts derived from primary cultures of human dermal fibroblasts fall into seven types, based on morphology and patterns of protein synthesis, that are a function of population doubling number and time kept in secondary culture ( Bayreuther et al., 1988). Many sources of fibroblasts have been demonstrated to support the growth of undifferentiated cells, but the sources most frequently used in the laboratory are mouse embryonic fibroblasts (MEFs) and human foreskin fibroblasts.
