Tissue engineering and regenerative medicine have emerged as crucial disciplines focused on the development of new tissues and organs to overcome the limitations of traditional treatments for tissue damage caused by accidents, diseases, or aging. Strontium ion (Sr) has garnered significant attention for its multifaceted role in promoting regeneration medicine and therapy, especially in bone tissue regeneration. Recently, numerous studies further confirm that Sr also plays a critical in soft tissue regeneration. This review firstly summarizes the influence of Sr on critical biological processes such as osteogenesis, angiogenesis, immune modulation, matrix synthesis, mineralization, and antioxidative defence mechanisms. Then details the classification, properties, advantages, and limitations of Sr-containing biomaterials (SrBMs). Additionally, this review extends to the current applications of SrBMs in regenerative medicine for diverse tissues, including bone, cartilage, skeletal muscle, dental pulp, cardiac tissue, skin, hair follicles, etc. Moreover, the review addresses the challenges associated with current SrBMs and provides insights for their future designing and applications in regenerative medicine.

3-O-sulfation of heparan sulfate (HS) is the key determinant for binding and activation of Antithrombin III (AT). This interaction is the basis of heparin treatment to prevent thrombotic events and excess coagulation. Antithrombin-binding HS (HSAT) is expressed in human tissues, but is thought to be expressed in the subendothelial space, mast cells, and follicular fluid.

MS4A4A belongs to the MS4A tetraspan protein superfamily and is selectively expressed by the monocyte-macrophage lineage. In this study, we aimed to evaluate the role of MS4A4A+ macrophages in rheumatoid arthritis (RA) pathogenesis and response to treatment. RNA sequencing and immunohistochemistry of synovial samples from either early treatment-naïve or active chronic RA patients showed that MS4A4A expression positively correlated with synovial inflammation.

Histological preparation paraffin embedding is the gold standard method for evaluating tissue structure and composition, whether it is originated from biopsy or engineered . Quite often, deformation and shrinkage occur during the histological preparation, which are difficult to predict and qualify. The present study investigates the morphometric changes in bioprinted hydrogels composed of alginate and gelatine, common tissue engineering materials, focusing on three morphologies: full slabs, porous slabs, and porous cubes.

Wounds with extensive tissue damage are highly susceptible for microbial infections delaying the process of wound healing. Currently, biomaterials with therapeutic molecules emerged as key players in wound repairing. This work developed a novel collagen-based hydrogel loaded with allicin and silver nanoparticles.
