Novel fabricated matrix via electrospinning for tissue engineering

TLDR

Electrospinning is emerging as a practical method to produce novel porous filaments with unique structures and affordable mechanical properties. The study aimed to assess the feasibility of plain‑woven, porous PCL filaments as three‑dimensional scaffold matrices. PCL was dissolved in methylene chloride/N,N‑dimethylformamide mixtures (100/0, 75/25, 50/50 v/v) and electrospun, with the resulting filaments coagulating via phase‑separation to form porous strands that were then woven into plain fabrics. The electrospun filaments ranged from 0.5 to 12 µm in.

Abstract

Abstract Electric field‐driven fiber formation (electrospinning) is developing into a practical means for preparing novel porous filament with unusual structures and affordable mechanical properties. Polycaprolactone (PCL) was dissolved in solvent mixtures of methylene chloride/ N , N ‐dimethyl formamide with ratios of 100/0, 75/25, and 50/50 (v/v) for electrospinning. The filament was formed by coagulation of the spinning solution following the well‐known principle of phase separation in polymer solutions valid in other wet shaping processes. A strand of electrospun porous filament consisted of fibers ranging from 0.5 to 12 μm in diameter. To evaluate the feasibility of three‐dimensional fabric as scaffold matrices, the plain weave, which is the simplest of the weaves and the most common, was prepared with porous PCL filament. The growth characteristics of MCF‐7 mammary carcinoma cells in the woven fabrics showed the important role of matrix microstructure in proliferation. This study has shown that woven fabrics, consisting of porous filaments via electrospinning, may be suitable candidates as tissue engineering scaffolds. © 2004 Wiley Periodicals, Inc.
