TISSUE ENGINEERING
TISSUE ENGINEERING Tissue engineering is a multidisciplinary field that aims to repair, replace, or regenerate damaged or diseased tissues and organs using a combination of cells, biomaterials, and growth factors. Here’s an overview of its key components, applications, and challenges: 1. Components Cells: The foundation of tissue engineering; can be sourced from the patient (autologous cells) or from donors (allogeneic cells). Stem cells are often used for their ability to differentiate into various cell types. Scaffolds: Biodegradable materials that provide structural support for cells to grow and organize into functional tissues. Scaffolds can be made from natural or synthetic materials, designed to mimic the extracellular matrix (ECM). Growth Factors: Proteins that stimulate cell proliferation, differentiation, and tissue regeneration. These factors can be incorporated into scaffolds or delivered through controlled-release systems. 2. Types of Tissue En...
