intussusceptiivinen
Intussusceptiivinen is a Finnish adjective used in biology and medicine to describe processes that involve inward folding or insertion of tissue, structures, or membranes. In practice the term is most often applied to intussusceptive angiogenesis, a mode of blood vessel formation where new vessels arise by internal partitioning of existing ones rather than by sprouting from new tips.
Intussusceptive angiogenesis differs from sprouting angiogenesis in that it relies on the formation of transvascular pillars
The term is used primarily in vascular biology, developmental biology, and pathology. It is important to distinguish
Intussusceptive mechanisms occur in various contexts, including embryonic development, organ remodeling, wound healing, and tumor-associated angiogenesis.
