And, in cell culture in the laboratory, cells can change shape or may lose specific properties such as protein expression—which processes are also termed dedifferentiation. [ 17 ] Some hypothesize that dedifferentiation is an aberration that likely results in cancers , [ 18 ] but others explain it as a natural part of the immune response that ...
Metaplasia occurs when a cell of a certain type is replaced by another cell type, which may be less differentiated. It is a reversible process thought to be caused by stem cell reprogramming. Stem cells are found in epithelia and embryonic mesenchyme of connective tissue. A prominent example of metaplasia involves the changes associated with ...
Overview of signal transduction pathways involved in apoptosis. Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, as in programmed cell death, or may result from factors such as diseases, localized injury, or the death of the organism of which the cells are part.
Newer cell fate determination techniques include lineage tracing performed using inducible Cre-lox transgenic mice, where specific cell populations can be experimentally mapped using reporters like brainbow, a colorful reporter that is useful in the brain and other tissues to follow the differentiation path of a cell.
Morphogenesis (from the Greek morphê shape and genesis creation, literally "the generation of form") is the biological process that causes a cell, tissue or organism to develop its shape. It is one of three fundamental aspects of developmental biology along with the control of tissue growth and patterning of cellular differentiation .
Routine plant maintenance is anecessary part of raising healthy,happy flowers and shrubs.Two of the most common types of manualcare include deadheading and pruning.As its name implies, deadheading ...
Cell damage (also known as cell injury) is a variety of changes of stress that a cell suffers due to external as well as internal environmental changes. Amongst other causes, this can be due to physical, chemical, infectious, biological, nutritional or immunological factors.
Deadheading your plants—clipping off the spent blossoms—is a super-easy way to encourage flowers to bloom more. Here are some tips on how to deadhead correctly.
