NIH3T3 Cell Line:
The mouse fibroblast cell line NIH 3T3 has been extensively employed in multiple studies and is considered one of the most frequently used fibroblast cell lines. NIH3T3 are derived from a cell line of a Swiss mouse embryo established in 1962 by two scientists at the Department of Pathology in the New York University School of Medicine. The 3T3 cell line has become the standard fibroblast cell line. Mouse embryonic fibroblasts NIH3T3 is a type of murine embryonic fibroblast cells (MEF). MEFs are often used as feeder cells in human embryonic stem cell research and for the maintenance of embryonic stem cells in the undifferentiated state. Feeder cells serve as a basal layer for other cultures and have been utilized to support the nourishment and proliferation of other cell types including stem cells. Cell layers of feeder cells cannot divide, but they secrete growth factor to the culture media, supporting the growth of target cells. MEF cell line is an excellent host for studies related to mammalian embryonic tissue, frequently employed as a transfection host in cell and molecular biology research. Many various MEF cell lines exhibit slightly different characteristics. MEF cells are also used for titration of viruses from mouse organs and tissues in lab studies. NIH3T3 cells are utilized in the cultivation of keratinocytes, with the 3T3 cells secreting growth factors favorable to keratinocytes. It has been found that NIH3T3 cells are inhibited by benzodiazepines. The 3T3 designation is an abbreviation of “3-day transfer, inoculum 3 x 10e5 cells“. NIH3T3 cells line is a good transfection host susceptible to sarcoma and leukemia viruses. Altogen Biosystems offers lipid-based transfection reagent kits for the NIH-3T3 cell line that yield high transfection efficiency, as detected by qRT-PCR.
Figure 1. GAPD mRNA levels were quantified using real-time RT-PCR in NIH3T3 cells transfected with siRNAs targeting GAPD or non-silencing siRNA. Forty-eight hours post-transfection, the cells were harvested and analyzed by real-time RT-PCR for GAPDH mRNA expression levels. Data were normalized against the 18S rRNA signal. Control samples were either mock-transfected or untreated. Values are normalized to untreated sample. Data are means ± SD (n=3).
Figure 2. Protein expression of GAPDH in NIH3T3 cells. DNA plasmid expressing GAPDH or siRNA targeting GAPDH were transfected into NIH3T3 cells following Altogen Biosystems transfection protocol. At 72 hours post-transfection the cells were analyzed by Western Blot for protein expression levels (normalized by total protein, 10 µg of total protein loaded per each well). Untreated cells used as a negative control.
