  7. 5. Identifying Graph Characteristics in Growing Vascular Networks

    Master-uppsats, Uppsala universitet/Tillämpad beräkningsvetenskap

    Författare :Christopher Finn Plummer; [2024]
    Nyckelord :Anigogenesis; Vascular Networks; Network Science;

    Sammanfattning : One of the ways that a vascular network grows is through the process of angiogenesis, wherebya new blood vessel forms as a branch from an existing vessel towards an area which isstimulating vascular growth. Due to the demands for nutrients and waste transport, growingtumour cells will access the surrounding vascular network by inducing angiogenesis. LÄS MER
