A New TGF-β Mimetic, XEP™-716 Miniprotein™, Exhibiting Regenerative Properties Objectivized by Instrumental Evaluation.
Abstract
Skin aging, which results from intrinsic and extrinsic factors, is characterized by a rough, uneven and wrinkled appearance of the skin at the macroscopic level. At the microscopic level, aging shows lowered keratinocyte turnover, flattened dermal-epidermal junction and reduced collagen fiber density; however, use of skin biopsies to evaluate characteristic properties of these microscopic changes is too limiting for panelists and rarely used. The development of non-invasive techniques is an opportunity to be considered for such evaluations. Our objective was to demonstrate the rejuvenating effects of XEP™-716 Miniprotein™ on skin, a miniprotein having TGF-β beta-like properties, in vitro on normal human fibroblasts and at the clinical level.

Research summary
The paper investigates the rejuvenating effects of a TGF-β mimetic on skin aging, which is directly related to the biological processes of aging. However, while it presents a novel approach to skin rejuvenation, the findings appear to be more focused on symptomatic treatment rather than addressing the root causes of aging. Thus, while it contributes to the field of regenerative medicine, its overall impact is limited and more incremental than groundbreaking.
