What does vascularized mean?
Vascularized is a technical term meaning supplied with blood vessels or possessing an established vascular network. It is used especially in medicine, anatomy, biology, and tissue engineering to describe organs, lesions, grafts, or experimental materials that contain vessels. The term is relevant wherever the presence or development of blood vessels affects healing, circulation, surgery, or the viability of tissue. For example, a tumor described as highly vascularized contains an unusually rich blood supply, while a tissue-engineering scaffold may be vascularized to help it survive after implantation. The word comes from vascular, which refers to blood vessels, and the suffix -ize, which forms words meaning to make or bring into a particular condition. It is distinct from avascular, meaning without blood vessels. British English often spells the word vascularised, whereas vascularized is standard in American English.
Having blood vessels or being supplied with them.
"The graft remained vascularized and developed a functional blood supply."
Common in medical, anatomical, and tissue-engineering contexts.
To furnish tissue or a structure with blood vessels, or to make it vascular.
"The researchers vascularized the engineered tissue before transplantation."
Less common than the adjective use and generally found in specialist biological and medical writing.
A vascularized tissue is not just tissue: it has a living network of vessels carrying oxygen, nutrients, and cells.

Where does vascularized come from?
The word is formed in English from vascular, meaning “of or relating to vessels,” with the suffix -ize meaning “to make” or “to furnish with.” Vascular derives from Latin vascularis, a form of vasculum, “a small vessel” or “vessel,” which is a diminutive of the Latin vas, “vessel.” The resulting forms vascularize and vascularized developed the meaning of making something vascular or supplying it with blood vessels; the spelling vascularised is common in British English.

How vascularized is actually used
This is primarily a formal medical and biological term. American English commonly uses vascularized, while British English often uses vascularised. It may describe an existing blood-vessel network or the process of establishing one.
Easily confused with vascularized
Vascularized specifically indicates that blood vessels are present or have been supplied, whereas vascular more broadly means relating to or involving vessels.
