Studies of Human and Tunicate Cellulose and of their Relation to Reticulin

D. A. Hall, Hedwig Saxl

Abstract

The cellulose-containing fibres which have been reported as normal constituents of mammalian dermis, have been compared with the other example of animal cellulose-tunicin- and deductions made concerning the possible evolutionary significance of these observations, especially in relation to the phylogenetic development of reticulin. The genetical significance of their incidence in ageing aortic tissue and in pathological conditions of the dermis has been studied and further evidence obtained on the basis of which it is possible to correlate their formation both in vivo and in vitro with the degradation of connective tissue proteins.
