I was just reading this article and these words struck me:
an optical technique that takes just a few seconds to sculpt complex tissue shapes in a biocompatible hydrogel containing stem cells. The resulting tissue can then be vascularized by adding endothelial cells.
Not only can they render complex 3D structures that becomes living tissue they can vascularize it as well.
Could they also do the same for a lymphatic system?
How are they coaxing the Stem cells to become the tissue types they want?
But the real reason I was given to pause was the young me from the 1950s inside that had it’s little mind blown by that statement. So much has changed in my lifetime. So much science fiction becoming realized.
