  Bone is a remarkable material, strong enough to withstand impressive forces without fracturing. Despite decades of research, however, our understanding of the molecular mechanisms underlying bone’s fracture resistance has remained incomplete. It has long been hypothesized that collagen degradation occurs following bone fracture. Until recently, this hypothesis lacked empirical evidence due to a...

  Chronic kidney disease (CKD) progressively impairs kidney function, affecting millions. Beyond kidney-related complications, patients often experience muscle weakness and reduced mobility, begging the question: does muscle fibrosis contribute to those limitations? Figure 1 demonstrates a significant increase in collagen deposition within the vastus lateralis muscle of CKD patients. Histochemical analysis using picro-sirius red...

Collagen Hybridizing Peptides (CHPs) are revolutionizing the study of scleral inflammation.  See how CHPs are used to visualize collagen degradation and uncover new insights into diseases like scleritis.

(b) Confocal micrographs of heart tissue sections from Ccr2-RFP × Cx3cr1-GFP mice 10 days post-ischemia-reperfusion (I–R) injury show the infarct border zone versus remote myocardium. A biotin-conjugated CHP, detected with a streptavidin-conjugated Alexa 647 secondary antibody (purple), visualized immature or denatured collagen, pinpointing areas of active ECM remodeling. Stem cell therapy has long been...

Antioxidant-loaded small extracellular vesicles (sEVs) enhance muscle regeneration and accelerate collagen turnover, offering a promising cell-free therapy for skeletal muscle atrophy. Using Collagen Hybridizing Peptides (CHPs), researchers quantified collagen remodeling and showed how sEVs stimulate recovery in atrophic muscles. Learn how this innovative approach combines antioxidant-loaded sEVs and CHPs to drive tissue repair and...

UV light exposure causes skin damage, leading to wrinkles, roughness, and accelerated aging. While retinoids are effective anti-aging treatments, they often cause skin irritation. This study highlights a breakthrough alternative using retinal (RAL), combined with plant-derived retinol analogs like bakuchiol (BAK) and Vigna aconitifolia extract (VAE). Research on UV-damaged skin demonstrated that this combination...

Metformin pre-treatment enhances extracellular matrix (ECM) remodeling and reduces muscle fibrosis during bed rest, with critical insights provided by collagen hybridizing peptides (CHPs). By increasing type I myofiber size and decreasing cellular senescence markers, metformin promotes healthier muscle recovery and improves collagen turnover. This approach, supported by CHP technology, shows promise as an anti-inflammatory...

While chimeric antigen T (CAR-T) cells have shown immense promise as a cancer therapeutic, they have limited efficacy in treating solid tumors. This is due to immune exclusion, whereby physical barriers such as stromal cells woven into dense extracellular matrices prevent anti-cancer immune cells from reaching the tumor.
