Advancements in Bone Regeneration: Using Bioactive Glass as a Scaffolding Material

The video discusses research at Chelsea and Westminster Hospital on regrowing diseased or damaged bone. Professor Julia Pollock and her team tested bioactive glass, a material used in dentistry, on human bone cells. The glass encouraged cell growth by acting as scaffolding. The team aims to develop a treatment combining bioactive glass with a patient's bone marrow, and eventually with stem cells, to treat bone disease without rejection.

What is the main issue with current artificial joints and anchoring techniques?

• They cause allergic reactions.

• They are difficult to manufacture.

• They have a limited lifespan.

• They are too expensive.

What substance did Professor Julia Pollock and her team test on human bone cells?

• Bioactive glass

• Hydroxyapatite

• Calcium phosphate

• Titanium alloy

How does bioactive glass help in bone cell growth?

• By providing nutrients

• By acting as a scaffold

• By increasing blood flow

• By reducing inflammation

What is the proposed combination treatment for bone disease?

• Mixing bioactive glass with antibiotics

• Using bioactive glass with metal implants

• Combining bioactive glass with bone marrow

• Applying bioactive glass with vitamin supplements

What is the ultimate goal of using bioactive glass with human stem cells?
