Chitosan has been broadly utilized in bone scaffold production because of its antibacterial qualities, low toxicity, biodegradability, biocompatibility, and ability to aid regeneration processes wound healing. In this work, chitosan was produced from crab shell waste through demineralization, deproteination, deacetylation, utilizing HCl 1:7 (v/v), NaOH 3%, 1:10 (v/w), 50%. The aim study is exam...
Performance of PRP Associated with Porous Chitosan as a Composite Scaffold for Regenerative Medicine
This study aimed to evaluate the in vitro performance of activated platelet-rich plasma associated with porous sponges of chitosan as a composite scaffold for proliferation and osteogenic differentiation of human adipose tissue-derived mesenchymal stem cells. The sponges were prepared by controlled freezing (-20, -80, or -196°C) and lyophilization of chitosan solutions (1, 2, or 3% w/v). The pl...
Background and purpose: The use of bioactive glass-ceramics in medicine has been noticed because of their ability in directly connection to bony tissue and bone repairing. Chitosan is also nontoxic material and biologically is compatible with the capability of biodegradation. However, due to the minimally invasive nature of injectable systems and their ability to make scaffold in place of using...
This study used a rat subcutaneous implantation model to investigate gradual in situ pore formation in a self-regulating degradable chitosan-based material, which comprises lysozyme incorporated into biomimetic calcium phosphate (CaP) coatings at the surface to control the scaffold degradation and subsequent pore formation. Specifically, the in vivo degradation of the scaffolds, the in situ por...
A technique for producing micrometer-scale structures over large, nonplanar chitosan surfaces is described. The technique makes use of the rheological characteristics (deformability) of the chitosan to create freestanding, three-dimensional scaffolds with controlled shapes, incorporating defined microtopography. The results of an investigation into the technical limits of molding different comb...
Chitosan hydrogels are of considerable interest in synthetic biomimetic mineralisation strategies due to their favourable characteristics such as the presentation of a large surface area for crystal nucleation within a structured yet responsive scaffold. Chitosan hydrogels were prepared and subsequently calcium carbonate mineralisation was initiated using a method which combines alternate soaki...
