Abstract
An in vitro method for screening for candidate compounds for preventing and/or attenuating skin ageing, and/or hydrating skin, includes: a) contacting a test compound with a sample of papillary fibroblasts; b) measuring the expression of a gene selected from PDPN, CCRL1 and NTN1, in the papillary fibroblasts; and c) selecting compounds for which an activation of at least 1.5 fold of the expression of at least one of the genes is measured in the treated papillary fibroblasts compared with untreated papillary fibroblasts. Another in vitro method includes: a) contacting a test compound with a sample of reticular fibroblasts; b) measuring the expression of a gene selected from MGP, PPP1R14A and TGM2, in the reticular fibroblasts; and c) selecting compounds for which an activation of at most 1.0 fold of the expression of at least one of the genes is measured in the treated reticular fibroblasts compared with untreated reticular fibroblasts.
