Blood can be processed in various ways to obtain cell preparations, which can then be used directly in biological assays or further processed to isolate more specific cell subsets. Whole blood is composed of plasma, red blood cells RBCs; or erythrocytes , platelets, and nucleated white blood cells, also referred to as leukocytes.
The leukocytes can be further categorized into mononuclear cells and polymorphonuclear cells or granulocytes. Here we outline different techniques to obtain peripheral blood mononuclear cells PBMCs , polymorphonuclear cells, leukocytes, or specific cell subsets.
Isolation of specific cell types for functional studies or downstream assays may require RBC depletion during the cell preparation step. There are several ways to deplete RBCs, including:. After the RBC depletion is complete, the resulting sample will contain all nucleated white blood cells leukocytes that can be used for downstream assays or further processed to isolate a specific cell subset. PBMCs include lymphocytes i. T cells, B cells, and NK cells , monocytes, and dendritic cells, and are defined as white blood cells with round nuclei.
Preparation of a PBMC fraction from whole blood is a common step prior to the isolation of specific immune cell subsets. The most common PBMC isolation method involves using a density gradient medium e. This method takes advantage of the differences in density between the cells in blood and the density gradient medium. Whole blood is first diluted with phosphate buffered saline PBS and then carefully layered over the density gradient medium. During centrifugation, the cells with higher densities i.
The PBMCs settle at the interface between the density gradient medium and the plasma, from which they can be carefully collected. This fast isolation method results in purified PBMCs in as little as 20 minutes and works on whole blood, cord blood, bone marrow, buffy coats, and leukapheresis products.
Alternatively, you can purchase frozen PBMCs. After obtaining PBMCs, immunomagnetic cell separation and other cell isolation techniques can be used to isolate specific cell subsets. Find protocols and tools to help you isolate, source, freeze, and thaw human PBMCs in your research.
Polymorphonuclear cells, also known as granulocytes, are a collection of immune cell subsets with enzyme-containing granules that can be released upon cell activation. To obtain a population of polymorphonuclear cells from whole blood, you can do any of the following:. A buffy coat is a concentrated suspension of leukocytes and results when erythrocytes and plasma are separated from the leukocyte fraction by low speed centrifugation.
This procedure allows you to concentrate large sample volumes and remove donor-specific soluble serum factors, which helps to reduce donor variability. Some cell separation technologies e. Apheresis is a process in which whole blood is drawn from an individual, separated into components, and reinfused back into the individual with a certain component e. Leukapheresis is a form of apheresis where leukocytes are collected from a donor's circulating blood. Leukopaks , which are enriched leukapheresis products containing higher concentrations of leukocytes per volume compared to whole blood or buffy coat, are an ideal starting source of mononuclear cells that can be used for immune cell isolation.
Depending on the method you choose, you can prepare a Leukopak for cell separation by either isolating the PBMC fraction from it or simply depleting RBCs prior to cell isolation. Plateletpheresis is another form of apheresis where thrombocytes, commonly called platelets, are separated from the rest of the blood.
LRSCs are usually discarded after routine donor plateletpheresis, but are an excellent source of leukocytes that can be used as an alternative source of PBMCs for research purposes. Cord blood can be collected from the placenta and umbilical cord after birth. Immune cells found in cord blood can be isolated to study early-life immune responses. To isolate specific cell populations from cord blood, you can first prepare mononuclear cells by using density gradient medium e.
Depleting RBCs from cord blood requires special considerations. Standard ammonium chloride lysis may be too harsh for the hematopoietic or immune progenitor cells contained in cord blood. Another factor to keep in mind is that cord blood can have very high platelet counts, which may facilitate the formation of clots. It is important to use suitable anticoagulants, like acid citrate dextrose ACD or EDTA, and to follow the manufacturer's instructions pertaining to cord blood when processing samples.

To obtain a population of polymorphonuclear cells from whole blood, you can do any of the following: Perform density gradient centrifugation followed by ammonium chloride lysis. You can then isolate specific granulocyte populations such as neutrophils, basophils, or eosinophils using immunomagnetic cell separation technologies.
This approach allows you to quickly and easily obtain pan-granulocytes or one of the more specific granulocyte subsets e.

Do Blood Test Results Differ When Processed at Different Labs?
Torched forests and cities burned to the ground. Colleagues with severed limbs. Bombardments so relentless the only option is to lie in a trench, wait and pray. In interviews with The Associated Press, some complained of chaotic organization, desertions and mental health problems caused by relentless shelling.

Plans to design a smart phone app that can detect leukaemia will be among the innovations presented by Northumbria University researchers at the Centre for Life this weekend. It would work by taking a magnified image of a blood slide via a microscopic lens attached to the smart phone, which the app would then be able to screen for evidence of leukaemia — a blood cancer. Fellow Northumbria colleagues will also exhibit, including demonstrations of 3D printing, targeted drug delivery and an app that helps research the effect of the Himalayan Balsam plant on British bees. Billed as the greatest show-and-tell on Earth, it is a two-day celebration across the spectrum of science, engineering, art, performance and craft. A family-friendly gathering of tech enthusiasts, crafters, hobbyists, engineers, artists and more, the event aims to inspire and enthuse people of all ages. In , approximately , children and adults around the world developed some form of leukaemia with a similar number dying from the cancer. Once his project is complete, Worawut hopes it will help to prevent unnecessary deaths from the disease caused by delayed diagnosis and treatment due to poverty or living in remote areas far away from large hospitals and laboratories. More than Makers will exhibit their work during the international event in front of an anticipated audience in excess of 10, Highlights of Maker Faire UK include RoboHand, a huge hydraulically-powered robotic hand able to crush small cars in its grip, and Roboknit — a life-sized humanoid knitting robot.

T he COVID pandemic has led to a steep drop in blood donations, leading blood centers in the US to raise the alarm about critical shortages , laying bare the fragility of the current blood supply. For years, scientists anticipating disruptions to the blood supply—due to issues such as emerging pathogens that can be transmitted through blood or the rapidly aging population, which could drastically reduce the number of potential donors in the future—have been working on developing ways to produce blood in factories in order to provide an alternative source of the vital substance. Oh and his colleagues set out with the mission of finding ways to manufacture RBCs—which alone are sufficient for blood transfusions—from iPSCs at scale in At the time, Oh says, the available approaches were unable to develop enough high-quality immature blood cells, called erythroblasts, to expand and mature in large bioreactors—one of the reasons being that scientists were primarily using monolayer cultures, which limited how much the cells could grow. To do so, they attached the iPSCs derived from various tissues to supportive structures called microcarriers that enable their growth, then placed them in cell cultures that were under constant agitation by shaking or stirring, for example. Growing dense cell cultures requires high levels of nutrients and oxygen, and a continuously agitated environment offers more of those critical components to reach the growing cells than a static environment does, Oh explains. Oh has patents for the techniques used in this study, and is the founder of Zenzic Labs and SingCell, two Singapore-based biotechnology companies working with stem cells. Throughout this process, different cocktails of cytokines were added at various stages to induce differentiation into erythroblasts.
