Summary: This study investigates the effects of Pro-Hyp on the differentiation of ATDC5 chondrogenic cells under hypoxic conditions. The results show that Pro-Hyp significantly promotes the early differentiation of chondrocytes under physiological hypoxic conditions, suggesting its potential role as a remodeling factor or extracellular matrix remodeling signal that regulates chondrocyte differentiation in hypoxic cartilage.

Summary: The study focuses on evaluating the efficacy of pro-resolving factors produced by macrophages after efferocytosis in treating IBD. Reintroduction of these factors was shown to reduce inflammation in colitis models and promote tissue repair, with TGF-beta, IGF-I and VEGF identified as key factors. The administration of these pro-resolving factors released by efferocytic macrophages represents an innovative treatment approach for IBD.

Summary: A novel collagen-like peptide, col4a1, extracted from amputated earthworms has been found to enhance wound healing by promoting fibroblast viability, proliferation, migration, granulation, and collagen deposition. The peptide functions through binding with integrin alpha(2)beta(1) and upregulating the RAS/MAPK signaling pathway.

Summary: Collagen mimetic peptides (CMPs) have promising applications in tissue engineering, regenerative medicine, and biomaterials. This study explores the self-assembly of small CMPs to form large-scale collagen structures, and demonstrates the use of choline chloride (ChCl) to manipulate the stability and aggregation of CMP triple helices. These findings contribute to the understanding of factors responsible for triple helix stability and have potential implications for the discovery of new biomaterials.

Summary: The present study developed a L-proline conjugated chitosan scaffold for wound healing. The scaffold was characterized by various tests and showed no cytotoxicity. In vitro experiments demonstrated that the modified scaffold promoted wound closure and collagen deposition. These findings suggest that the L-proline conjugated scaffold has potential as a wound dressing to improve wound healing.

Summary: The study revealed that Staphylococcus aureus affects dermal fibroblasts, leading to impaired tissue repair functions such as upregulation of pro-inflammatory cytokines and degradation of collagen. This impact is not limited to specific cell sources and affects key mechanisms of wound healing.

Summary: Recruiting key cells to regeneration sites is a promising strategy for promoting functional wound healing. Papillary fibroblasts, with central regulatory roles in skin appendage regeneration, can be recruited using Grass Carp Fishing multifunctional hydrogels, which deliver Lrig1 antibodies and IGF1 to the surface of these fibroblasts. Injectable self-healing multifunctional hydrogels, with sustained release of Lrig1 antibodies and IGF1, were shown to accelerate the migration and proliferation of Lrig1(+) fibroblasts and promote wound healing and skin regeneration.

Summary: In this study, 3D-QSAR analysis was performed to investigate the structure-activity relationship of collagen hydrolysate peptides. The results showed that Hyp, rather than Pro, had a greater impact on improving antiplatelet activity. The predicted peptide EOGE exhibited antiplatelet activity and inhibited thrombus formation.

Summary: This study represents the first individual pharmacokinetics of Gly-Pro-Hyp, Pro-Hyp, and Gly-Pro in vivo. Gly-Pro-Hyp and Pro-Hyp showed a double-peak phenomenon after oral administration, while Gly-Pro had low levels in systemic circulation. Gly-Pro-Hyp tended to exhibit higher first-pass metabolism than Pro-Hyp.
