Authentic human blood that does not originate from a living human donor — metaphorically “orphaned,” as it has no “parent.”

It is the product of advanced tissue engineering that involves the ex vivo (outside the body) production of functioning human organs.

Orphan blood is harvested from a bioreactor, wherein hematogenic stem cells are propagated on a matrix of microscopic polymer scaffolding within a flowing broth of nutrients and vitamins.
