When two germ cells form a zygote, the "weak" one is assimilated by the stronger one, like food digestion. [5] This theory also explains vegetative hybridization, as the heredity in the scion may diffuse into the stock, resulting in a change in the stock's offspring. The vegetative hybridization theory was further tested on animals by injecting ...
Cell potency is a cell's ability to differentiate into other cell types. [1] [2] The more cell types a cell can differentiate into, the greater its potency.Potency is also described as the gene activation potential within a cell, which like a continuum, begins with totipotency to designate a cell with the most differentiation potential, pluripotency, multipotency, oligopotency, and finally ...
The three spent time in the "good" cell where they received clothing, beds, and food denied to the rest of the jail population. After an estimated 12 hours, the three returned to their old cells that lacked beds. Guards were allowed to abuse their power to humiliate the inmates.
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1] [2] All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. [3] Cell biology is the study of the structural and functional ...
The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope.
Confocal microscopic image of a colony of human induced pluripotent stem cells derived from a patient with oculocutaneous albinism. Red indicates transcription factor Oct-4, green the protein SSEA4, and blue the nuclei of the cells. Human iPS cells colonies. The spindle-shaped cells in the background are mouse fibroblast cells.
Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.
By using human embryonic stem cells to produce specialized cells like nerve cells or heart cells in the lab, scientists can gain access to adult human cells without taking tissue from patients. They can then study these specialized adult cells in detail to try to discern complications of diseases, or to study cell reactions to proposed new drugs.
