Cancer cells stimulate new blood vessel growth by releasing: angiogenic factors. telomerase. autocrine growth factors. lysosomal enzymes.

The correct answer is that cancer cells stimulate new blood vessel growth by releasing angiogenic factors. Angiogenic factors such as the vascular endothelial growth factor or VEGF is released by most cancer cells to stimulate blood vessel growth to supply the tumor's nutritional needs. 

Telomerase is an enzyme that adds nucleotides to telomeres, the structure at the end of chromosomes. This enables the cancer cell to multiply continuously. Autocrine growth factors is the ability of the cancer cell to produce its own growth factors. Lysosomal enzymes are enzymes that are activated by a cell during apoptosis.

angiogenic factors.

Cancer cells are dependent on the natural formation of new blood cells (neovascularization). To stimulate its growth, they need to release angiogenic factors.

the angiogenic factor is a group of substances (most of which are polypeptides— angiogenin, fibroblast growth factor, some lipids) which play a role in blood vessel formation./
