Abstract

Bone tissue is the structural component of the body, which allows locomotion, protects vital internal organs, and provides the maintenance of mineral homeostasis. Several bone-related pathologies generate critical-size bone defects that our organism is not able to heal spontaneously and require a therapeutic action. Conventional therapies span from pharmacological to interventional methodologies, all of them characterized by several drawbacks. To circumvent these effects, tissue engineering and regenerative medicine are innovative and promising approaches that exploit the capability of bone progenitors, especially mesenchymal stem cells, to differentiate into functional bone cells. So far, several materials have been tested in order to guarantee the specific requirements for bone tissue regeneration, ranging from the material biocompatibility to the ideal 3D bone-like architectural structure. In this review, we analyse the state-of-the-art of the most widespread polymeric scaffold materials and their application in in vitro and in vivo models, in order to evaluate their usability in the field of bone tissue engineering. Here, we will present several adopted strategies in scaffold production, from the different combination of materials, to chemical factor inclusion, embedding of cells, and manufacturing technology improvement.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • One drawback associated with natural materials is the lack of tunable degradation that can be achieved with synthetic polymers or the need for chemical modification of the natural polymers to achieve tunable degradation.

    “One drawback that has been associated with natural materials is the lack of tunable degradation that can be achieved with synthetic polymers or the need for chemical modification of the natural polymers to achieve tunable degradation [13].”

    From Keratin Scaffold Formulation Impacts rhBMP-2 Biodistribution and Bone Regeneration in a Rat Femur Defect Model (2025) · cites this paper as [13]

    Section 3 (Natural Polymers; page not provided) identifies reduced tunability and uncontrollable degradation rate as drawbacks of natural polymers. Section 4 (Synthetic Polymers; page not provided) says synthetic polymers can have their degradation rates adjusted. The passages do not establish that natural polymers need chemical modification to achieve tunable degradation. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
