Dermal fibroblast fibroblast and a corneal fibroblasts are placed in the same concentrations of fibroblast growth factor, dermal fibroblast will not differentiate or change. As noted by Dr. J. Lewis and Dr. A. Johnson authors of "Microbiology of the Cell", "fibroblasts from the skin are different" and behave differently from other fibroblast cells to identical chemical stimuli. Furthermore, dermal fibroblasts are less likely to replicate in either "in vivo" and "in vitro" environments than are other fibroblast types. Dermal fibroblasts require far higher concentrations of fibroblast growth factor (FGF) in order to undergo cell replication. Dermal fibroblasts are responsible for creating the
Embodied cognitive science can have an understanding of the human body. So the argument goes that if one lacked a human body, they could not possibly know what up or down could mean, or how it could relate to emotional states. ‘[I]magine a spherical being living outside of any gravitational field, with no knowledge or imagination of any other kind of experience. What could UP possibly mean to such a being?' While this does not mean that such beings would be incapable of expressing emotions in other words, it does mean that they would express emotions differently from humans. Human concepts of happiness
