Homunculi instead of guinea pigs

The idea of creating an "artificial human" Homunculus is simple and this makes it even more ingenious: to place human cells on a plate the size of a credit card and combine them with a system of "vessels" in the likeness of a living organism.

Another target for the treatment of diabetic retinopathy

In addition to the already known vascular growth factor, another signaling protein, angiopoietin–4, is involved in the destruction of the retina in diabetes, which is also involved in the appearance of new vessels, and that their blocking successfully prevents the growth of defective capillaries.
