Cytobiology
At different levels (microscopic, ultramicroscopic and molecular levels), it mainly studies cell structure and function, cell proliferation, differentiation, ageing and apoptosis, cell signal transduction, eukaryotic gene expression and regulation, cell origin and evolution. The main contents of its research include the study of the nucleus, chromosome and gene expression, the study of biofilm and organelles, the study of cytoskeleton system, cell proliferation and its regulation, cell differentiation and its regulation, cell ageing and apoptosis, cell origin and evolution, and cell engineering.
The cell is the basic unit of the organization and function of an organism and the basic unit of life activities. All organisms from single cells to higher animals and plants are composed of cells. Cells are the basic unit of all animals and plants, and all cells come from existing cells. Cell biology is a science that uses modern technology and methods to study the basic rule of cell life activities from different levels such as cells, ultrastructure and molecules. Medical cell biology is a subject based on cell biology and molecular biology to explore and study the relationship between human cell genesis, development, appreciation, ageing, death, abnormal cell structure and function and human diseases. Molecular cell biology is a subject that mainly studies the structure and function of cells and the laws of various life activities at the molecular level. It represents the mainstream and level of the development of modern cell biology and is the latest stage of the development of cell biology.
