Electrospining Machine: Electrospun nanofiber scaffolds for bone tissue engineering applications

 Literature introduction

The treatment of bone defects and bone diseases has been an important area of research in clinical medicine. Although traditional grafting has achieved better results in treating these problems, it still suffers from some limitations. Electrostatically spun nanofibre scaffolds are considered ideal materials in the field of bone tissue engineering due to their unique structural properties and bioactivity.

What are the relevant applications of electrostatic spinning in tissue engineering?

1. Repair of hard bone defects: 

Bone defects, which may be caused by various reasons such as trauma, fracture, tumour resection, etc., seriously affect the quality of life of patients, and electrostatically spun nanofibre scaffolds, as an advanced artificial bone tissue scaffold, can not only significantly improve the speed and quality of bone regeneration, but also customize personalized treatment plans according to the specific size and shape of the bone defects, so as to effectively repair the defects, restore the bone structure and function, and improve the patients' quality of life. quality of life.

2. Cartilage damage repair:

Electrostatically spun nanofibrous scaffolds provide an effective tissue engineering strategy for cartilage injury repair due to their properties of promoting cell adhesion, proliferation and differentiation, as well as customisability and biocompatibility.

3. Interaction of electrostatically spun nanofibre scaffolds with bone-forming cells:

Electrostatically spun nanofibre scaffolds are capable of guiding bone-forming cell differentiation and mimicking bone tissue properties by tuning the chemical composition and micro- and nanostructures to promote cell adhesion, signalling and interaction with bone-forming cells.

4. Delivery of bioactive substances:

Electrostatically spun nanofibre scaffolds promote new bone formation in bone tissue engineering by adsorbing and releasing biologically active substances (e.g. BMPs and FGF), which play a key role in guiding cell migration, proliferation and differentiation, and activate signaling pathways through interactions with cell-surface receptors, thus delivering biostimulation accurately and consistently to improve therapeutic outcomes in bone defect repair

5. Structural Bionic Design:

The electrostatic spinning technique is capable of preparing nanofibrous scaffolds with diverse structures that mimic the microenvironment of natural bone tissue by adjusting the spinning parameters, such as polymer concentration and electric field strength, and this biomimetic design facilitates cell attachment, growth, and enhances bioactivity and bone regeneration efficiency. In addition, the improved electrostatic spinning technique can also prepare three-dimensional PCL/PANI composite nanofibre macrostructures with good biocompatibility and promotion of cell proliferation and differentiation, which provides innovation and possibilities for bone tissue engineering.
