Document Summary
Looks like a fibroblasts and has all of the characteristics of in terms of its appearance. From a molecular standpoint, it is not a fibroblast (it does not do what a fibroblast does) Mesenchymal stem cells are multi potential cells: they can differentiate in different lineages: they are stem cells. Fibroblast: mesenchymal cell found in collagen-dense connective tissues, elongated morphology, produces extracellular matrix components, degrade/turnover the matrix. There are cells that are not the same: they can look similar histologically but not the same in terms of function. Cannot tell what a cell does based on its morphology because they can look the same when isolated molecular differences exist despite similar morphology. Histology cannot always tell you a lot about what you are looking at from a functional standpoint. Cells can look identical but have completely different functions. Mostly type i collagen, also some elastic and type iii collagen fibers.
