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, a group of researchers has found. 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, researchers say.
