Dermal fibroblast altering their actin gene expression (which is silenced in dermal fibroblasts). When dermal fibroblasts express actin, the cells can slowly contract. This contraction plays a critical role in wound healing and fibrosis. By pulling tissues closed differentiated myofibroblasts, seal the skin after an injury (thereby, preventing infection but inducing scar formation. Myofibroblasts can also be derived from non-fibroblast sources. Based on evidence of α-SMA expression from lung injuries, myofibroblasts can "arise de novo" directly from mesenchymal stem cells. Unlike other fibroblast cell types, dermal fibroblasts are far less likely to change into other cell types. For example, when a dermal
Body-to-body communication Body-to-body communication Body-to-body communication is a way of communicating with others through the use of nonverbal communication, or without using speech or verbalization. It can include "body language", facial expressions, and other bodily gestures in order to communicate with others without the need of verbal communication. Body-to-body communication accounts for postures, body language, positioning in the environment, nonverbal language, gestures, movements and in general the people as a whole. This form of communication accounts for roughly up to sixty percent of human conversation and can be expressed in many different forms. Body-to-body communication can be used in collaboration with, as
