Only 5 papers within a Experiment Title: Cytotoxicity Test discussion solution. I want to solve the text of the keyboard. Thank you, Experiment no. 2 sir 1 12:34 PMA Objectives: Study the eytotoxicity and how it is measured. 1- Background Cytotoxicity can lead healthy living cells to three potential cellular fates. 1. Necrosis (accidental cell death): Rapid loss of membrane integrity and cell lysis 2. Apoptosis (programmed cell death): slower, more orderly, and genetically controlled 3. Cytostasis (a decrease in cell viability): cells remain alive but fail to actively grow and divide Importance of measuring cytotoxicity two major reasons 1. Either you want specific cells to die and look for an adequate compound/condition (cancer and immunotherapy) 2. Or you want to exclude cytoloxicity in specific cells (chemicals and drugs)…
