WebThe fact that we see metastasis is that one cell or lump of cells detached from the tumor and via blood/lymphoid system reached a new destination (let's say lungs) and now grows in the lungs. It is not that one cancerous cell transformed lung cell into cancerous, but original cancerous cell divides and eventually outnumber lung cells. 2 comments WebThe amount of apoptosis that occurs in developing and adult animal tissues can be astonishing.

WebApoptosis can be initiated through one of two pathways. In the intrinsic pathway the cell kills itself because it senses cell stress, while in the extrinsic pathway the cell kills itself because of signals from other cells. Weak external signals may … WebExplain how apoptosis occurs. Cellular agents chop up the DNA and fragment the organelles and other cytoplasmic components. The cell shrinks and becomes lobed, a changed called "blebbing," and the cell;s parts are packaged up in vesicles that are engulfed and digested by specialized scavenger cells.
