A photo of human embryonic stem cells (the cell colonies in the center). Spindle cells surrounding the stem cell colony are MEFs. Mouse Embryonic Fibroblasts (MEFs) are a type of fibroblast prepared from mouse embryo. MEFs show a spindle shape when cultured in vitro, a typical feature of fibroblasts. The MEF is a limited cell line.
A fibroblast is a type of biological cell typically with a spindle shape [1] that synthesizes the extracellular matrix and collagen, [2] produces the structural framework for animal tissues, and plays a critical role in wound healing. [3] Fibroblasts are the most common cells of connective tissue in animals.
3T3 cells are several cell lines of mouse embryonic fibroblasts. The original 3T3 cell line (3T3-Swiss albino) was established in 1962 by two scientists then at the Department of Pathology in the New York University School of Medicine, George Todaro and Howard Green .
As the cell divides, the telomeres on the end of a linear chromosome get shorter. The telomeres will eventually no longer be present on the chromosome. This end stage is the concept that links the deterioration of telomeres to aging. Top: Primary mouse embryonic fibroblast cells (MEFs) before senescence. Spindle-shaped.
Human iPS cells colonies. The spindle-shaped cells in the background are mouse fibroblast cells. Only those cells comprising the center colony are human iPS cells. Induced pluripotent stem cells (also known as iPS cells or iPSCs) are a type of pluripotent stem cell that can be generated directly from a somatic cell.
Immortal cell lines are a very important tool for research into the biochemistry and cell biology of multicellular organisms. Immortalised cell lines have also found uses in biotechnology . An immortalised cell line should not be confused with stem cells , which can also divide indefinitely, but form a normal part of the development of a ...
It is secreted by various cells, primarily fibroblasts, as a soluble protein dimer and is then assembled into an insoluble matrix in a complex cell-mediated process. Fibronectin plays a major role in cell adhesion, growth, migration, and differentiation, and it is important for processes such as wound healing and embryonic development. [6]
Recently, the term "fibrocyte" has also been applied to a bloodborne cell able to leave the blood, enter tissue and become a fibroblast. As part of the more general topic of stem cell biology, a number of studies have suggested that the blood contains marrow derived cells that can differentiate into fibroblasts. These cells have been reported ...
