Can cells grow larger
WebApr 7, 2024 · Some cells can grow to very large sizes through a specialized cell cycle called endoreplication. In this division, the genome is replicated during the S phase but there will be no M phase or cytokinesis. The resulting cell will have many copies of the genome and become polyploid. Polyploidy is a common phenomenon seen in cancer cells. WebJun 20, 2024 · A recent clinical trial has started evaluating the safety and tolerability of a novel therapy involving a virus that can infect and kill human cancer cells. Cancer is a large group of diseases that occur when abnormal cells divide rapidly and can spread to other tissue and organs. These rapidly growing cells may cause tumors.
