Cytolysis, or osmotic lysis, occurs when a cell bursts due to an osmotic imbalance that has caused excess water to diffuse into the cell. Water can enter the cell by diffusion through the cell membrane or through selective membrane channels called aquaporins, which greatly facilitate the flow of water. It occurs in a hypotonic environment, where water moves into the cell by osmosis and cause… WebJun 21, 2024 · Although signs of cytopathic effects and cell degeneration remained prominent in the cultures, evidence of cellular proliferation in the scarce islands could be observed. ... metabolic functions enabling the cells to continuously survive and grow without actively undergoing apoptosis or cytolysis, despite active intra-cellular propagation of …
