Dermal fibroblast wound site perish. Without fibroblasts, the wound site cannot regenerate extracellular matrix and epidermis skin cells cannot proliferate over the wound site. Therefore, without dermal fibroblasts the skin cannot properly recover from injury. Yet, by differentiating mesenchymal stem cells from other regions of the body and injecting them into the wound site, scientists can restore dermal fibroblasts to burned regions of the body. By restoring fibroblasts to the burned regions, the body can restore the ECM within the wound site and recover from the injury. As noted "The injured dermis is also repaired by the recruitment and proliferation of fibroblasts
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.
