WebAbstract. In the past few years much has been learned about the molecular signals governing apoptosis, or programmed cell death, in lymphocytes and other cells of the immune system. Two major pathways, active and passive apoptosis, have been identified and are discussed in this overview. Active apoptosis, also termed propriocidal cell death … 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 datagridview text alignment
