HeLa-S3 Cell Line:
The HeLa S3 cell line is a derivative of the immortal HeLa cell line and is also considered immortal, sharing many similar properties with the HeLa cell line, as a result. The difference between the famous HeLa cell line and the HeLa S3 cell line is that S3 represents the third clone isolated and propagated from the original HeLa culture. The letter S was used in honor of Dr. Florence Rena Sabin, though this cell line originated in the lab of Dr. Theodore Puck. HeLa S3 was established in 1955 and has been used for studies in cloning of mammal cells. It also has similar properties to the famous HeLa cell line, named after Henrietta Lacks, from which it was derived. The HeLa cell line was established using cervical cancer cells taken in 1951 from Henrietta Lacks, a patient who eventually died of her cancer later that year. The HeLa cell line considered an “immortal” cell line and had been used in a wide variety of scientific research. These cells have received a lot of media attention, due to the controversy surrounding patient’s rights. HeLaS3 cells are very similar to the original HeLa cells in terms of their morphology, growth characteristics, and genetic makeup. However, there are some important differences between the two cell lines. HeLaS3 cells tend to be more homogeneous in their growth and morphology, making them easier to work with in certain types of experiments. They also have a different karyotype (chromosome number and arrangement) than the original HeLa cells. HeLaS3 cells have been used in a wide variety of research areas, including cancer biology, virology, and drug discovery. Like the original HeLa cells, they are known for their ability to grow rapidly and continuously in culture, making them an ideal model system for studying the effects of drugs, toxins, and viruses on human cells. They have been used to study the mechanisms of tumor development and progression, to develop new cancer therapies, and to study the life cycles of viruses such as HIV and human papillomavirus (HPV). The HeLa cell line was in fact the first human cell line to be able to establish itself and be successful in a cell culture. In addition to being an indispensable tool in conducting a wide variety of specialized biomedical applications, the HeLa S3 is beneficial for mammalian cloning research. The HeLa S3 transfection reagent kit for cervical adenocarcinoma offered by Altogen Biosystems, among many other transfection products, yields high transfection efficiency of siRNA delivery. Besides, it produces high-level recombinant protein expression with minimal disruption of cell function and has low cytotoxicity.
Figure 1. Cyclophilin B silencing efficiency was determined by qRT-PCR in the Hela-S3 cells transfected by Cyclophilin B siRNA or non-silencing siRNA control following the recommended transfection protocol. Cyclophilin mRNA expression levels were measured 48 hours post-transfection. 18S rRNA levels were used to normalize the Cyclophilin B data. Values are normalized to untreated sample. Data are presented as means ± SD (n=6).
Figure 2. Protein expression of Cyclophilin B in HeLa-S3 cells. DNA plasmid expressing Cyclophilin B or siRNA targeting Cyclophilin B were transfected into HeLa-S3 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.
