Uninhibited Angiogenesis is one of the Torso Augmentations in Deus Ex: Mankind Divided.
Description[]
After growing accustomed to the flow of synthetic and supportive growth factors, the Angiogenesis Protein Therapy augmentation finally shuts down all production of growth factor inhibitors. This allows the body itself to guide the continued development of vascular tissue. Eventually, the user's body naturally reaches the maximum threshold of capillary saturation and can now experience massive trauma without bleeding to death or losing organ function. It's not immortality, but it's the closest thing available with current technology.
