What is fetal cow blood used for?

FBS is the liquid portion that remains after blood is drawn from bovine fetus coagulates. It's the most widely used serum supplement for in-vitro cell culture (for eukaryotic cells). Additionally, it plays a vital role in the research of human and veterinary vaccines and has applications in stem cell research.

What is fetal blood used for?

The serum which is obtained from fetal blood, is used for scientific purposes such as vaccine production. RSPCA Australia advocates the use of non-animal alternatives instead of blood being collected from fetuses and for these to be developed as quickly as possible.

What is Fetal Bovine used for?

Fetal bovine serum is the most widely used serum-supplement for the in vitro cell culture of eukaryotic cells. This is due to it having a very low level of antibodies and containing more growth factors, allowing for versatility in many different cell culture applications.

How do they extract fetal bovine serum?

Fetal bovine serum (FBS) is a common component of animal cell culture media. It is harvested from bovine fetuses taken from pregnant cows during slaughter. FBS is commonly harvested by means of a cardiac puncture without any form of anaesthesia.

Why is fetal calf serum used in mammalian cell and tissue culture?

Benefits of fetal bovine serum

Serum is added to culture medium at a concentration of 2-10% to provide attachment factors, nutrients, and hormones for mammalian cells, as well as to be a buffer against disruptions like pH changes and endotoxins.

Who uses fetal bovine serum?

Fetal bovine serum (FBS) is a byproduct of harvesting cattle for the meatpacking industry—it's used extensively by both academic and industrial researchers as a supplement to basal growth medium in cell culture applications. FBS is the liquid portion that remains after blood is drawn from bovine fetus coagulates.

Is fetal bovine serum ethical?

Fetal bovine serum is both a scientifically and a morally problematical product. Its application in cell culture experiments represents a scientific problem, as FBS is undefined, and changes in its composition may interfere with the outcome of experiments.

Why is FBS so expensive?

The extra market has created a more significant burden on the serum supply, pushing up pricing. The limitation of the available supply from USDA-approved sources to the United States has increased U.S. pricing.

What is the difference between fetal calf serum and fetal bovine serum?

Fetal Bovine Serum is the same as Fetal Calf Serum. There is no difference and semantics have no place in science, and anyone working with cells should know that.

Is fetal bovine serum safe?

Out of all bovine blood products, Fetal Bovine Serum is considered the safest one since sourced from an unborn animal.

What is bovine blood?

Bovine blood is made up of 80.9% water, 17.3% protein, 0.23% fat, 0.07% carbohydrate, and 0.62% minerals (Alencar, 1983). Blood composition is similar to meat composition except for the iron (36.3 mg/100 g of blood), which is ∼10 times the concentration in meat (Wismer-Pedersen, 1979; Alencar, 1983).

What does Foetal bovine serum contain?

Fetal bovine serum contains a sparse amount of gamma globulin, higher levels of growth factors, and fewer complement proteins than both calf and adult bovine serum.

What is present in fetal bovine serum?

There are 1000+ components found in FBS, including proteins, electrolytes, lipids, carbohydrates, hormones, enzymes, and other undefined constituents, which are necessary in many culture conditions to support cell growth.

How can I get fetal blood?

Fetal blood sampling is a procedure used to diagnose, treat or monitor various fetal problems. Using a very small needle, specialists in Maternal-Fetal Medicine are able to remove a tiny amount of blood from the fetus during pregnancy.

Why is bovine serum albumin used in vaccines?

Bovine serum albumin (BSA) is a major component of fetal bovine serum (FBS), which is commonly used as a culture medium during vaccine production. Because BSA can cause allergic reactions in humans the World Health Organization (WHO) has set a guidance of 50 ng or less residual BSA per vaccine dose.

Can I use FBS instead of horse serum?

Fetal calf serum and Fetal Bovine serum are the same,but horse serum is different in growth factors. Conventionally, Fetal calf serum ismostly used for growing cells and depending on the type of cell and your protocol that will determine the FCS concentration.

Can I use FBS instead of FCS?

There is no difference between FBS and FCS, it is the same serum with name preference. However, the 'F' for fetal is very important, and catalog numbers from different companies are critical for cell culture.

Why does fetal bovine serum promote cellular proliferation?

FBS has very low level of antibodies and contains more growth factors than calf and adult bovine serum, thus allowing the propagation of most types of human and animal cells.

Does lab-grown meat use FBS?

In reality, it turns out that many lab-grown meat products actually contain a shocking amount of blood. More specifically, they often rely on fetal bovine serum (FBS), or blood taken from unborn cow fetuses, Mother Jones reports.

Is cell based meat vegan?

Cell-cultured meat is definitely controversial, particularly in the vegan community. While it is (allegedly) cruelty-free, it is still an animal and not a plant. So eating it is technically not vegan. But it does skip over the process of factory farming and the slaughter of animals, so it could be considered ethical.

Can meat be grown in a lab?

Lab-grown meat isn't artificial meat. It's real animal flesh. It just happens to grow in a lab, not on a factory farm. Scientists are even working to ensure that lab-created muscle tissue mimics the exact texture of traditionally-grown meat.

Why is fetal bovine serum bad?

One of the major concerns is the risk of contamination of FBS/media with harmful pathogens such as prions, viruses, Mycoplasma, or other unidentified zoonoses that can be transmitted to the host, causing detrimental immune reactions from the MSC therapy.

How long can FBS be stored at?

Liquid FBS and other serum may be stored refrigerated (2 to 8 °C) up to four weeks.

What growth factors are in fetal bovine serum?

Bovine serum albumin is the major component of FBS. Growth factors in FBS are essential for the maintenance and growth of cultured cells [1, 2]. FBS also contains a variety of small molecules like amino acids, sugars, lipids, and hormones. FBS is used in a wide range of applications.
