BALB/c is an albino, laboratory-bred strain of the house mouse from which a number of common substrains are derived. Now over 200 generations from New York in 1920, BALB/c mice are distributed globally, and are among the most widely used inbred strains used in animal experimentation.
BALB/c laboratory mice BALB/c is an albino laboratory-bred strain from which a number of common substrains are derived. With over 200 generations bred since 1920, BALB/c mice are distributed globally and are among the most widely used inbred strains used in animal experimentation .
The inbred strain of C57BL mice was created in 1921 by C. C. Little at the Bussey Institute for Research in Applied Biology. [1] The substrain "6" was the most popular of the surviving substrains. Little's supervisor William E. Castle had obtained the predecessor strain of C57BL/6, "mouse number 57", from Abbie Lathrop who was breeding inbred ...
Nude mice were the earliest immunodeficient mouse model. These mice primarily produced IgM and had minimal or no IgA. As a result, they did not exhibit a rejection response to allogeneic tissue. Commonly utilized strains included BALB/c-nu, Swiss-nu, NC-nu, and NIH-nu, which were extensively employed in the research of immune diseases and tumors.
4T1 is a breast cancer cell line derived from the mammary gland tissue of a mouse BALB/c strain. [ 1 ] 4T1 cells are epithelial and are resistant to 6-thioguanine . [ 1 ] In preclinical research, 4T1 cells have been used to study breast cancer metastasis as they can metastasize to the lung, liver, lymph nodes, brain and bone.
Mice are good jumpers, climbers, and swimmers, and are generally considered to be thigmotactic, i.e. usually attempt to maintain contact with vertical surfaces. [citation needed] Mice are mostly crepuscular or nocturnal; they are averse to bright lights. The average sleep time of a captive house mouse is reported to be 12.5 hours per day.
In 1909, Clarence C. Little developed the first inbred strain, the DBA (Dilute, brown non-Agouti) mouse. In 1915, N.M Haldane identified first linkage in mouse between Albino mice and pink eye dilution on chromosome seven. In 1921, C57BL became one of the most widely used mice in genetics and was the first strain to have its genome sequenced.
NIH-3T3 fibroblasts in cell culture.. 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.
