Question

)Judah Folkman performed an experiment in which he found that small tumors floating in the anterior chamber of the eye grew little, whereas a similar tumor implanted directly onto the iris grew to thousands of times its original size. These results supported his idea that continued tumor growth is dependent on requirement of tumor growth for Select an answer and submit.

Answer 1

The correct answer is c angiogenesis.

Step-by-step explanation:

Blood vessels are an important component of the tumor stroma and therefore angiogenesis is a predictor of prognosis in many human neoplasms and so much so that it is considered that there is an important correlation between the number and density of blood vessels with the metastatic states, tumor size, histological type, and consequently degree of tumor malignancy. Angiogenesis is an essential process for progressive tumor growth and the ability to metastasize. New capillaries are formed in response to angiogenic substances secreted by tumor cells, as well as normal tissue infiltrating the tumor (such as fibroblasts and macrophages). Carrying out tumor growth requires new vessels and identification of factors that mediate tumor growth. Angiogenesis allows us to understand this pathological process and the diagnosis of the essential stage of tumor differentiation and organization.
