Bone Tissue Regeneration

Bone Tissue Regeneration

Part of: GS Prelims and GS -III – Biotechnology; Science and tech

In news: A nano biomaterial with a stable link between two molecules was recently synthesized at Savitribai Phule Pune University, India. The development may soon help in tissue regeneration. 

What is a Biomaterial?

• It is a biological or synthetic substance which can be introduced into body tissue as part of an implanted medical device or used to replace an organ, bodily function, etc.

About Bone tissue regeneration 

• Critical size bone defects due to trauma or disease. These are very difficult to repair via the natural growth of host tissue. 
• Therefore, there exists a need to fill these defects with a bridging (usually porous) material (termed scaffold), which should also, in combination with relevant cells and signaling molecules, promote the regeneration of new bone tissue. 
• The biomaterials of choice for the development such scaffolds should exhibit bioactive properties i.e. react with physiological fluids and form tenacious bonds for bone formation.
