Investigating the factors involved in skin rejuvenation processes, researchers have identified the role of hyaluronan and proteoglycan link protein 1 (HAPLN1) in restoring collagen and hyaluronic acid in aged skin [1]. The most noticeable sign of aging Skin aging, one of the most visible forms of aging, is influenced by both intrinsic and extrinsic factors....

Researchers publishing in Aging Cell have investigated the biology of skin cells taken from people who don't produce the senescence-related compound p16. A necessary evil Why we Age: Cellular SenescenceAs your body ages, more of your cells become senescent. Senescent cells do not divide or support the tissues of which they are part; instead, they...

In Aging, researchers have described how the changing production of skin cells' proteins is a core part of their age-related decline. Understanding why skin cells lose their function In healthy skin, dermal fibroblasts produce the proteins needed to maintain the extracellular matrix (ECM), the network of collagen and elastin that holds soft tissues together [1]....

Scientists have found a way to reprogram fibroblasts without chemicals by culturing them on a surface with specific mechanical properties. Transplanted into aged skin, those cells boosted rejuvenation in a human tissue model [1]. We've all got skin in the game Skin aging might not be the deadliest part of organismal aging, but it certainly...

According to a new study published in Nature Scientific Reports, while both aerobic and resistance exercise improve some aspects of skin aging, only the latter is able to increase skin thickness [1]. Exercise and skin – an overlooked connection Skin is the largest organ of the human body, providing a barrier that keeps us safe...

Scientists have demonstrated that extracellular vesicles loaded with mRNA coding for collagen production can be easily produced and delivered into aging fibroblasts in vitro and in vivo, boosting collagen levels and eliminating signs of skin aging in mice [1]. Superior delivery method Finding a good way to deliver molecular cargo into cells is important. Some...
