Spider silk biology for biomedical applications - Anna Rising

Our research is mainly focused on using spider silk technology for various medical applications.

Biomimetic spinning of artificial spider silk

We use spider silk technology for medical applications. One line of our research concerns making artificial spider silk fibers for use in regenerative medicine, mainly cultivation of stem cells. The fibers we make are strong as tendons, are biocompatible and degrade as new tissue is formed.

Another line of research concerns the use of a spider silk protein domain for efficient production of proteins and peptides, in particular for the generation of novel lung surfactant preparations.

Our lab is located at Karolinska Institutet and at the Swedish University of Agricultural Sciences (SLU).

Some of our research problems

  • Will we be able to mimic the mechanical properties in natural spider silk fibers, in artificially made spider silk fibers? 
  • Will we be able to replace damaged tissues and organs by using artificially produced spider silk as implants?
  • Will we be able to produce valuable and aggregation prone proteins with low solubility by using Nature's own solubility increasing domain (NT)?
  • Will we be able to make surfactant preparations that are more resistant to inhibition and can we use Lung surfactant as a drug delivery vehicle?
