Researchers began a study of a cultured cell line. their preliminary observations showed them that the cell line did not exhibit either density-dependent inhibition or anchorage dependence. what could they conclude right away?

The correct answer will be - cells are cancerous or tumor forming cells

Explanation:

The cells show the property of differentiation, dedifferentiation and redifferentiation usually but cells which forget to differentiate and show continuous growth become cancerous.

The cancerous cells due to uncontrolled division can form a tumour in which cells lack the density-dependent inhibition or the inhibition of growth reaching the limit.  The cells also lack the property of anchorage dependence which is the ability of the cells to adhere themselves to each other and communicate.

Thus, cells are cancerous or tumour-forming cells is the correct answer.
