This altered extracellular environment has been hypothesized to result as an effect of reduced gravity - driven forces acting on the cell - fluid system and has been put forth as the biophysical mechanism governing bacterial behavior in space. (sciencedaily.com)
The team reasoned that these aggregations must create their own extracellular environment, which allows the papillae to interact and release signals that ultimately reprogram the recipient skin to grow new follicles. (sciencedaily.com)
Also, it is well - known that body cells alter their extracellular environment by exchanging chemicals, generating heat, and so on.8 (religion-online.org)
