AI Article Synopsis

  • Hyaluronan-based microgels with an artificial extracellular matrix were developed using a microfluidic technique and incorporated into a HA/collagen hydrogel, enhancing the retention of noncrosslinked sHA3.
  • The modified gels showed an increased binding capacity for transforming growth factor-β1 (TGF-β1) compared to standard HA/collagen hydrogels.
  • These advancements suggest potential for creating new biomaterials that can control the release of sHA3 and interact with growth factors, which could aid in skin repair by normalizing TGF-β1 levels.

Article Abstract

Hyaluronan (HA)-based microgels generated in a microfluidic approach, containing an artificial extracellular matrix composed of collagen and high-sulfated hyaluronan (sHA3), were incorporated into a HA/collagen-based hydrogel matrix. This significantly enhanced the retention of noncrosslinked sHA3 within the gels enabling controlled sHA3 presentation. Gels containing sHA3 bound higher amounts of transforming growth factor-β1 (TGF-β1) compared to pure HA/collagen hydrogels. Moreover, the presence of sHA3-containing microgels improved the TGF-β1 retention within the hydrogels. These findings are promising for developing innovative biomaterials with adjustable sHA3 release and growth factor interaction profiles to foster skin repair, e.g., by rebalancing dysregulated TGF-β1 levels.

Bone remodelling, important for homeostasis and regeneration involves the controlled action of osteoblasts, osteocytes and osteoclasts. The present study established a three-dimensional human bone model as triple culture with simultaneously differentiating osteocytes and osteoclasts, in the presence of osteoblasts. Since high sulfated hyaluronan (sHA3) was reported as a biomaterial to enhance osteogenesis as well as to dampen osteoclastogenesis, the triple culture was exposed to sHA3 to investigate cellular responses compared to the respective bone cell monocultures.

Corneal scarring caused by epithelial-stromal injury impairs corneal transparency and visual acuity. Excess secretion of transforming growth factor-beta 1 (TGF-β1), which promotes wound closure, penetrates the corneal stroma via defects in the epithelial basement membrane and induces the differentiation of corneal fibroblasts to myofibroblasts, leading to scar formation. Modulating TGF-β1 penetration might alleviate corneal scar formation and restore transparency.

The WNT signaling pathway is a central regulator of bone development and regeneration. Functional alterations of WNT ligands and inhibitors are associated with a variety of bone diseases that affect bone fragility and result in a high medical and socioeconomic burden. Hence, this cellular pathway has emerged as a novel target for bone-protective therapies, e.

Bone in diabetes mellitus is characterized by an altered microarchitecture caused by abnormal metabolism of bone cells. Together with diabetic neuropathy, this is associated with serious complications including impaired bone healing culminating in complicated fractures and dislocations, especially in the lower extremities, so-called Charcot neuroarthropathy (CN). The underlying mechanisms are not yet fully understood, and treatment of CN is challenging.

We examined whether sulfated hyaluronan exerts inhibitory effects on enzymatic and biological actions of heparanase, a sole endo-beta-glucuronidase implicated in cancer malignancy and inflammation. Degradation of heparan sulfate by human and mouse heparanase was inhibited by sulfated hyaluronan. In particular, high-sulfated hyaluronan modified with approximately 2.
