CHU Cardiology Unit Dijon, 21000 Dijon, France Correspondence: [email protected]; Tel.: +33-Received: 18 March 2020; Accepted: 7 April 2020; Published: 9 AprilAbstract: Human skin is composed of 3 layers: the epidermis, the dermis, and the hypodermis. The epidermis has four significant cell layers produced up of keratinocytes in varying stages of progressive differentiation. Skin aging is usually a multi-factorial approach that affects each phase of its biology and function. The expression profiles of inflammation-related genes analyzed in resident immune cells demonstrated that these cells have a powerful ability to regenerate adult skin stem cells and to generate endogenous substances including growth differentiation factor 11 (GDF11). GDF11 appears to be the important to progenitor proliferation and/or differentiation. The preservation of youthful phenotypes has been tied for the presence of GDF11 in distinctive human tissues, and, in the skin, this element inhibits inflammatory responses. The protective part of GDF11 will depend on a multi-factorial process implicating numerous kinds of skin cells such as keratinocytes, CDK4 Formulation fibroblasts and inflammatory cells. GDF11 must be additional studied for the goal of creating novel therapies for the treatment of skin diseases. Keywords and phrases: skin aging; regeneration; growth elements; disease1. Introduction The skin may be the largest organ in the human body. Despite the fact that it can be less than 2 mm thick in most places, it accounts for about 15 of an adult’s total body weight.
