Genetically engineered fibers of the protein spidroin, which is the construction material for spider webs, has proven to be a perfect substrate for cultivating heart tissue cells, MIPT researchers found. They discuss their findings in an article that has recently come out in the journal PLOS ONE.
The cultivation of organs and tissues from a patient’s cells is the bleeding edge of medical research – regenerative methods can solve the problem of transplant rejection. However,it’s quite a challenge to find a suitable frame, or substrate, to grow cells on. The material should be non-toxic and elastic andshould not be rejected by the body or impede cell growth.
