Interviews with our collagen experts

Collagen plays an important role in the regeneration of tissue. This is why Geistlich Pharma has devoted itself to collagen expertise.Eleven scientists working at Geistlich Pharma have dedicated themselves exclusively to collagen research. Niklaus Stiefel,  Head Material Research Biochemistry, advances with his team the company’s 160 years of collagen expertise with their work.

How can one modify a protein so that it has either this or that property?

Many people think that it has something to do with which one of the 30 different types of collagen one uses, but in fact it is a question of the original tissue and how it is processed. It’s like when you are looking for a house. You can either buy a complete, ready-built detached house, or you can buy the individual bricks and assemble something completely new.

What do you think are the most important aspects for a clinician using Geistlich collagen membranes or matrices?

...that the outcome is predictable, that no surprises will occur, and that he will be able to send his patient home happy. That’s why we do our research: to push for successful outcomes, no matter how experienced a clinician might be.

One last question: What is a collagen researcher’s dream?

In principle, all tissue can be regenerated using the right collagen. It really would be a dream come true to be able to facilitate this: to be able to help cells so that they themselves can regenerate tissue that has been lost or destroyed, like skin, heart or liver tissue. In this regard, we hope to “turn back the clock” – to encourage tissues to regenerate to their former, healthy states.
