"Artificial organs?"
He Ao gazed at the Kors before him, "Are they from animals... or... "
"Human organs," Kors continued He Ao's question, "To be precise, human cloned organs."
He glanced at He Ao and went on to explain,
"We all know that the human body develops from a single fertilized egg cell.
"During the whole development process, the fertilized egg continuously divides and multiplies.
"The multiplying cells differentiate into different limbs and organs. For instance, some become skin cells, kidney cells, while others become red blood cells, white blood cells.
"Through this environmental adaptation of differentiation, we finally construct the complex structure of the human body as we know it.
"Generally speaking, it's almost impossible for highly differentiated cells to change into entirely different types of functional cells. For example, skin cells directly transforming into kidney cells is virtually impossible.
