Back to top How often should I subculture a cell line?
ATCC: Frequently Asked QuestionsAnswer: Subculture refers to the transplantation of cells from one vessel to another. The term subculture is synonymous with the terms passage and split. The subculture interval is the time between subsequent subcultures. The subculture number is simply the number of times a culture has been transferred from one vessel to another. Adherence-dependent cell lines are generally subcultured either at or near confluency.
Related QuestionsWhat is a stem cell line?
jwsoccergurly's Xanga SiteObtained for research or other uses, a stem cell line is a living colony of stem cells in a laboratory. A stem cell line comes from either a human or animal tissue and it is continuously dividing the population of cells. Even thought they deteriorate, another name for it is ?mmortal?cell lines because these lines are established from the embryos shortly after fertilization. The government will be affected by making the decision.
Related QuestionsHow should I subculture a monolayer?
ATCC: Frequently Asked QuestionsAnswer: Refer to the product sheet included with your ATCC cell line for the subculturing procedure recommended for that particular cell line. Anchorage-dependent cell lines are usually subcultured by disaggregation of the cell sheet with proteolytic enzymes such as trypsin. Ethylenediaminetetraacetic acid (EDTA), a chelating agent, may be added to the dissociation solution to enhance the activity of the trypsin by removing calcium and magnesium from the surfaces of the cells.

Related QuestionsHow many students currently have land-line service, as opposed to cell phones?
Stanford Residential Computing: For Students: Services: In-R...In 2004-05, as of Winter quarter, 38% of undergraduate rooms and 60% of graduate rooms on campus had land-line service, or about 50% of all rooms on campus. Since a majority of students live in doubles, triples, or quads, the number of students, as opposed to the number of rooms, served by land-line telephones is higher than that. We estimate that 50% of undergraduates and 75% of graduate students on campus have land-lines in their rooms.
Related QuestionsWhat is the gothic subculture in the UK?
FAQThe word "gothic" is derived from the name of an early European tribe called the Visigoths, who enjoyed pillaging and raping and were famous for being uneducated and lacking in artistic taste. The term was also used from the middle ages onwards to describe a type of architecture; in particular cathedral arches with a sharp high point in the centre. Around the Victorian era, the label was also applied to horror novels by authors such as Edgar Allan Poe, Mary Shelly and Bram Stoker.
Related QuestionsBack to top Can a cell line be cured of mycoplasma contamination?
ATCC: Frequently Asked QuestionsAnswer: Yes, several lines in our collection have been cured of mycoplasma (e.g., ATCC CCL-229, ATCC HB-175). However, this process is time consuming and does not always work; discarding the culture and starting over is always the preferred method. As with other microbial infections, one should first identify the contaminant and select a suitable antibiotic, preferably by testing the contaminating mycoplasma for its antibiotic sensitivity.
Related QuestionsBack to top What are some factors that I must consider when depositing my cell line at ATCC?
ATCC: Frequently Asked QuestionsAnswer: Some factors to consider before submitting a new line are: 1) the cells should exhibit some unique characteristics or uses not exhibited by cells already in the collection; 2) the cell line should be documented in literature; 3) the cells must have a "useful" life expectancy in vitro, that is at least 15 to 20 doublings beyond the culture supplied; and 4) the cells should be free of contaminating microorganisms.

Growing embryonic stem cells in the laboratory is known as cell culture. The cells divide and spread over the surface of the culture dish, which is coated with connective tissue cells that have been treated so they will not divide. After stem cells replicate for several days, they crowd the dish. They are removed gently and replated into several fresh culture dishes.Related Questions
What is Cyberpunk, the Subculture ?
alt.cyberpunk FAQSpurred on by Cyberpunk literature in the mid-1980's, certain groups of people started referring to themselves as Cyberpunk, because they correctly noticed the seeds of the fictional "techno-system" in Western society today, and because they identified with the marginalized characters in Cyberpunk stories. Within the last few years, the mass media has caught on to this, spontaneously dubbing certain people and groups "Cyberpunk".
Related QuestionsBack to top How can I adapt a monolayer cell line to grow in suspension culture?
ATCC: Frequently Asked QuestionsAnswer: Not all cell lines can be adapted to suspension growth. In general, normal diploid anchorage-dependent (must be attached to a substrate to grow) cells cannot be adapted without the use of microcarrier beads to which they can attach. Lines such as L-929 (ATCC CCL-1) and HeLa (ATCC CCL-2) which are not anchorage-dependent can be adapted and variants that grow in suspension already exist.

Graduate School of Biomedical Sciences | Stem Cell Research ...A stem cell is an uncommitted cell that has the potential to develop into cells of a specific tissue (such as the hematopoietic stem cell developing into all of the blood cells). Within the fetus and the adult, stem cells are found in various areas of the body. Embryonic stem cells are the precursors to all stem cells as well as all other tissues of the body.

Related QuestionsWhat is the difference between primary cells and cell line?
Frequently Asked QuestionsCell cultures may be derived from primary explants or dispersed cell suspensions. Because cell proliferation is often found in such cultures, a confluent monolayer or a dense cell suspension is formed. According to the traditional definition, the first harvesting and subculturing of this cell population is called primary cells [Freshney, R.I. (1987). Culture of Animal Cells. A Manual of Basic Technique. (New York, Alan R. Liss, Inc.)].
