Immunological Labelling of Papillary Fibroblasts in Normal Skin

[0029] Samples of normal skin derived from plastic surgery were embedded in Tissue-Tek, frozen in liquid nitrogen and stored in a freezer at -80.degree. C. 4-micron-thick sections were prepared on a cryostat according to standard techniques. Labelling was performed using a conventional indirect immunofluorescence labelling technique (see Asselineau et al., J.I.D., 86, 181-186, 1986) with 20 ml per section of the PG4 monoclonal antibody in pure state (culture supernatant) (see Sorrell et al., The Histochemical Journal, 31, 549-558, 1999). 20 ml per section of an antibody directed towards mouse antibodies (mouse conjugate), obtained from the company Dako, were then placed on the sections and the sections were incubated according to the manufacturer's recommendation. After rinsing, the sections were contacted with a solution of PBS containing 0.5% propidium iodide, and then rinsed with PBS and mounted for observation under ...

Abstract

Whether or not a sample of skin or of a skin equivalent contains such amount of a papillary fibroblast population as to be considered a normal skin is determined by labelling said skin or skin equivalent with at least one antibody specific for papillary fibroblasts and evaluating the extent of such labelling as a marker for skin or skin equivalent quality.

Description

CROSS-REFERENCE TO PRIORITY APPLICATION[0001] This application claims priority under 35 U.S.C. .sctn.119 of FR-99 / 15292, filed Dec. 3, 1999, hereby expressly incorporated by reference.[0002] 1. Technical Field of the Invention[0003] The present invention relates to the use of at least one antibody specific for papillary fibroblasts as a marker for the quality of skin, in particular of a skin equivalent.[0004] 2. Description of the Prior Art[0005] It is of course well known that human skin consists of two closely linked compartments or strata, namely, the epidermis and the dermis.[0006] The epidermis is principally comprised of three cell types, keratinocytes, which themselves constitute the majority of the cells of the epidermis, melanocytes and Langerhans cells. These cells constitute a keratinized epithelium which is differentiated into superposed layers or strata surmounted by a layer of dead cells forming the stratum corneum.[0007] The dermis provides the epidermis with a solid ...
