Tissue Engineering and Regenerative Medicine
Tissue engineering and regenerative medicine is an interdisciplinary field focused on developing biological substitutes to restore, maintain, or improve tissue and organ function. By combining principles of biology, engineering, and material science, it involves creating scaffolds, using stem cells, and applying bioactive molecules to repair or replace damaged tissues. This innovative approach aims to address limitations of traditional transplants and treatments, offering new hope for healing injuries and degenerative diseases.

❓ Frequently Asked Questions
What is tissue engineering and regenerative medicine?
An interdisciplinary field seeking to create biological substitutes to restore, maintain, or improve tissue and organ function by combining biology, engineering, and materials science.
What is a scaffold in tissue engineering?
A biocompatible 3D framework that supports cell attachment, growth, and organization, often porous and biodegradable to allow tissue formation and eventual replacement by natural tissue.
What role do stem cells play in tissue engineering?
Stem cells can self-renew and differentiate into multiple tissue cell types, providing the building blocks to repair damaged tissue; sources include embryonic stem cells, iPSCs, and adult stem cells.
What other components are used with scaffolds in regenerative strategies?
Growth factors to direct cell behavior, bioreactors for dynamic culture, and scaffolds or decellularized extracellular matrix to provide structure and signals.
