have so far not included measurements of other (neuro)‐humoral factors such as
angiotensin, endothelin, and vasopressin. This information will clarify whether the
interstitial phenomena observed in the present experiments directly depend on
modulation of sympathetic activity rather then being mediated via the recruitment of
other systems known to influence extracellular matrix biology.
