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. Todaro and Green originally obtained their 3T3 cells from Swiss albino mouse ...
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.
Differentiated adipocytes in a 3T3-L1 cell line stained with Oil Red O. 3T3-L1 is a sub clonal cell line derived from the original 3T3 Swiss albino cell line of 1962. The 3T3 original cell line was isolated from a mouse embryo and propagated for this specific line of 3T3 cells is used to study adipose tissue-related diseases and dysfunctions.
Fibroblasts can also migrate slowly over substratum as individual cells, again in contrast to epithelial cells. While epithelial cells form the lining of body structures, fibroblasts and related connective tissues sculpt the "bulk" of an organism. The life span of a fibroblast, as measured in chick embryos, is 57 ± 3 days. [4]

Shown are nuclei of mouse NIH 3T3, stained with Hoechst and a segmentation in red. [8] Segmentation of cells is an important sub-problem in many of the fields below (and sometimes useful on its own if the goal is only to obtain a cell count in a viability assay). The goal is to identify the boundaries of cells in a multi-cell image.
The nucleus of senescent cells is characterized by senescence-associated heterochromatin foci (SAHF) and DNA segments with chromatin alterations reinforcing senescence (DNA-SCARS). [19] Senescent cells affect tumour suppression, wound healing and possibly embryonic/placental development and a pathological role in age-related diseases. [20]
In biology, tissue is an assembly of similar cells and their extracellular matrix from the same embryonic origin that together carry out a specific function. [1] [2] Tissues occupy a biological organizational level between cells and a complete organ.
