Microscopy and supporting data for osteoblast integration within an electrospun fibrous network

Area of Science:

• Biomaterials Science
• Tissue Engineering
• Cell Biology

Background:

• Poly(d,l-lactide-co-glycolide acid) (PLGA) electrospun nanofiber membranes are promising for bone regeneration.
• Understanding cell-material interactions is crucial for optimizing scaffold design.

Purpose of the Study:

• To provide supplementary data on the degradation of PLGA electrospun fibers.
• To detail the methodology for 3D imaging and analysis of osteoblast cell integration with PLGA scaffolds.
• To present quantitative data on cell growth within these nanofiber membranes.

Main Methods:

• Degradation analysis of PLGA fibers in medium and air.
• Focused Ion Beam (FIB) microscopy and Scanning Electron Microscopy (SEM) for "slice and view" tomography.
• 3D reconstruction and image analysis of cell-fiber interactions.
• Quantification of osteoblast cell growth.

Main Results:

• Fiber diameter distribution histograms illustrating degradation patterns.
• Detailed protocols for FIB-SEM tomography and 3D reconstruction.
• Visualizations of osteoblast cell integration within the electrospun nanofiber network.
• Quantitative data on cell proliferation and distribution.

Conclusions:

• The provided data enhances the understanding of PLGA nanofiber degradation and cell integration.
• The detailed imaging and analysis methods enable robust 3D visualization of cell-scaffold interactions.
• This data serves as a valuable resource for researchers in bone tissue engineering and regenerative medicine.
