“…48 Furthermore, Moy et al, demonstrated that fibroblasts from nodular and sclerosing BCC, produce more GAGs, when compared with normal fibroblasts. 49 The authors suggested that cells from superficial and nodular BCC types are capable of producing cytokines which alter stromal fibroblast production of GAGs and stimulate collagenase synthesis. 49 In addition, Bertheim et al, demonstrated that in nodular BCC, HA staining of the tumour strands was weak to moderate, denoting increased proliferative activity.…”
