AB  - Our goal was to create bioimitated scaffolding materials for biomedical purposes. The guiding idea was that we used an interpenetrating structural hierarchy of natural extracellular matrix as a “pattern” to design hydrogel scaffolds that show favorable properties for tissue regeneration. Polymeric hydrogel scaffolds are made in a simple, environmentally friendly way without additional functionalization. Gelatin and 2-hydroxyethyl methacrylate were selected to prepare interpenetrating polymeric networks and linear alginate chains were added as an interpenetrant to study their influence on the scaffold’s functionalities. Cryogelation and porogenation methods were used to obtain the designed scaffolding biomaterials. The scaffold’s structural, morphological, and mechanical properties, in vitro degradation, and cell viability properties were assessed to study the effects of the preparation method and alginate loading. Apatite as an inorganic agent was incorporated into cryogelated scaffolds to perform an extensive biological assay. Cryogelated scaffolds possess superior functionalities essential for tissue regeneration: fully hydrophilicity, degradability and mechanical features (2.08–9.75 MPa), and an optimal LDH activity. Furthermore, cryogelated scaffolds loaded with apatite showed good cell adhesion capacity, biocompatibility, and non-toxic behavior. All scaffolds performed equally in terms of metabolic activity and osteoconductivity. Cryogelated scaffolds with/without HAp could represent a new advance to promote osteoconductivity and enhance hard tissue repair. The obtained series of scaffolding biomaterials described here can provide a wide range of potential applications in the area of biomedical engineering.

AB  - The design and evaluation of novel 2-hydroxyethyl methacrylate/gelatin/alginate/
graphene oxide hydrogels as innovative scaffolding biomaterials, which concurrently are the suitable
drug delivery carrier, was proposed. The hydrogels were prepared by the adapted porogen leaching
method; this is also the first time this method has been used to incorporate nanocolloidal graphene
oxide through the hydrogel and simultaneously form porous structures. The effects of a material’s
composition on its chemical, morphological, mechanical, and swelling properties, as well as on
cell viability and in vitro degradation, were assessed using Fourier transform infrared spectroscopy
(FTIR), scanning electron microscopy (SEM), measurements of Young’s modulus, gravimetric method
and MTT test, respectively. The engineered hydrogels show good swelling capacity, fully hydrophilic
surfaces, tunable porosity (from 56 to 76%) and mechanical properties (from 1.69 to 4.78 MPa),
curcumin entrapment efficiency above 99% and excellent curcumin release performances. In vitro
cytotoxicity on healthy human fibroblast (MRC5 cells) by MTT test reveal that the materials are
nontoxic and biocompatible, proposing novel hydrogels for in vivo clinical evaluation to optimize
tissue regeneration treatments by coupling the hydrogels with cells and different active agents to
create material/biofactor hybrids with new levels of biofunctionality.
