Abstract

Bone tissue engineering uses various methods and materials to find suitable scaffolds that regenerate lost bone due to disease or injury. Poly(ε-caprolactone) (PCL) can be used in 3D printing for producing biodegradable scaffolds by fused deposition modeling (FDM). However, the hydrophobic surfaces of PCL and its non-osteogenic nature reduces adhesion and cell bioactivity at the time of implantation. This work aims to enhance bone formation, osteogenic differentiation, and in vitro biocompatibility via PCL scaffolds modification with Hydroxyapatite (HA) and Collagen type I (COL). This study evaluated the osteosupportive capacity, biological behavior, and physicochemical properties of 3D-printed PCL, PCL/HA, PCL/COL, and PCL/HA/COL scaffolds. Biocompatibility and cells proliferation were investigated by seeding human adipose tissue-derived mesenchymal stem cells (hADSCs) onto the scaffolds, which were analyzed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay, and 6-diamidino-2-phenylindole (DAPI) staining. In addition, the bone differentiation potential of the hADSCs was assessed using calcium deposition, alkaline phosphatase (ALP) activity, and bone-related protein and genes. Although all constructed scaffolds support hADSCs proliferation and differentiation, the results showed that scaffold coating with HA and COL can boost these capacities in a synergistic manner. According to the findings, the tricomponent 3D-printed scaffold can be considered as a promising choice for bone tissue regeneration and rebuilding.

  • PCL scaffold coated with collagen and HA showed enhanced proliferation and differentiation of human adipose tissue-derived mesenchymal stem cells through a synergistic effect.

    “PCL scaffold coated with collagen and HA showed enhanced proliferation and differentiation of human adipose tissue-derived mesenchymal stem cells through a synergistic effect.”

    From Nano-hydroxyapatite/collagen composite as scaffold material for bone regeneration. (2023) · cites this paper as [95]

    The Results (Biocompatibility of scaffolds; page unavailable) report increased proliferation of human adipose-derived stem cells on HA- and collagen-coated PCL scaffolds. The Results (Osteoinductivity of scaffolds; page unavailable) attribute higher ALP activity, a marker of osteogenic differentiation, to a synergistic effect of HA and collagen. The paper does not attribute the proliferation increase to that synergistic effect. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Coating collagen and HA can improve the overall bioactivity of the scaffold.

    “These results also substantiated that the coating of collagen and HA can improve the overall bioactivity of the scaffold.”

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.
