You have heard that cotton and silk threads can be woven into beautiful clothes. But have you heard some body cells can be woven into tissues and organs? Well this is exactly what the scientists at the University College London have done.
The team is using a technique of electrospraying to combine a stream of a viscous biodegradable polymer with a suspension of embryonic stem cells. Two stainless needles are used, one inside the other. When voltage is applied to the needles, the polymer and cells become charged and move towards an “earthed” copper ring a short distance beneath, emerging as a single thin thread.
Both sheets and 3D forms can be generated by implementing simple techniques. The polymer’s viscosity acts as adhesive. By DNA amplification methodology it was proved that the after weaving the stem cells maintained intact versions of the genes found in undifferentiated stem cells.
Such weaving of stem cells into synthetic tissues is an important advancement. Again these newly formed fabrics can be transplanted in a wide number of locations with positive results. The experts believe that the synthetic tissue could be a step towards fully functional artificial organs.
