  • Human CD4+ T Cells (pdf)
    T Cells have a key function in the adaptive immune system. They can either promote growth and differentiation of other immune cells or show suppressive function and down - regulate immune reactions.
  • Human Cryopreserved Activated CD8 T-Cells (pdf)
    CD8+ T cells are recognized as TC cells once they become activated and are generally classified as having a pre-defined cytotoxic role within the immune system. However, CD8+ T cells also have the ability to make some cytokines. Antigen presentation stimulates T cells to become either "cytotoxic" CD8+ cells or "helper" CD4+ cells. A cytotoxic T cell belongs to a sub-group of T lymphocytes that are capable of inducing the death of infected somatic or tumor cells; they kill cells that are infected with viruses (or other pathogens), or are otherwise damaged or dysfunctional. Most cytotoxic T cells express T-cell receptors ) that can recognize a specific antigenic peptide bound to Class I MHC molecules, present on all nucleated cells, and a glycoprotein called CD8, which is attracted to non-variable portions of the Class I MHC molecule. The affinity between CD8 and the MHC molecule keeps the TC cell and the target cell bound closely together during antigen-specific activation.
  • Human Cryopreserved CD14 Monocytes (pdf)
    Monocytes are circulating precursors of macrophages and dendritic cells that migrate from the blood stream across vascular endothelium for immunological surveillance, as well as respond to inflammation. They act as antigen-presenting immune cells and can phagocytize and degrade microbes and particulate matter. Monocytes can differentiate into several different cell types. The most common applications for Monocytes are the in vitro differentiation into monocyte-derived dendritic cells, macrophages, and osteoclasts as well as their use as phagocytic immune cells in immunology and infection biology. CD14 belongs to the family of LPS receptor antigens and is strongly expressed on the majority of Monocytes.
  • Human Cryopreserved CD19 B-Cells (pdf)
    B cells are lymphocytes that play a large role in the humoral immune response. The principal functions of B cells are to make antibodies against antigens, perform the role of antigen-presenting cells (APCs) and eventually develop into memory B cells after activation by antigen interaction. B cells are an essential component of the adaptive immune system.
  • Human Cryopreserved CD56 Natural Killer Cells (pdf)
    Natural Killer cells are large granular lymphocytes that are a type of cytotoxic lymphocyte critical to the innate immune system. They are differentiated from the common lymphoid progenitor and are known to differentiate and mature in bone marrow, lymph node, tonsils, spleen, and the thymus where the y then enter into circulation. NK cells express the surface marker CD56 in humans and provide rapid responses to virally infected cells. They respond to tumor formation and have the ability to recognize stressed cells in the absence of antibodies and major histocompatibility complex, allowing for a much faster immune reaction. Applications include analysis of receptor expression, cytokine secretion, or cell-cell interaction with other cells of the immune system.
  • Human Peripheral Blood Mononuclear Cells (PBMCs) (pdf)
    A peripheral blood mononuclear cell (PBMC) is defined as any blood cell with a round nucleus (i.e. a lymphocyte, a monocyte, or a macrophage). These blood cells are a critical component in the immune system to fight infection and adapt to intruders. The lymphocyte population consists of CD4+ and CD8+ T cells, B cells and Natural Killer cells, CD14+ Monocytes, and Basophils/Neutrophils/Eosinophils/Dendritic cells. These cells are often extracted from whole blood or from Leukopak using Ficoll, a hydrophilic polysaccharide that separates layers of blood, with monocytes and lymphocytes forming a buffy coat under a layer of plasma. This buffy coat contains the PBMCs.
  • Human Umbilical Cord Blood CD34+ Progenitor Cell Manual (pdf)
    CD34 is a well-known marker for primitive and bone marrow-derived progenitor cells, especially for hematopoietic and endothelial progenitors. ZenBio offers CD34+ progenitor cells in a phenotypically undifferentiat ed state. The progenitor cells ar e derived from cord blood of healthy donors and produced at the Zen-Bio facility. Progenitor cells contain two main cellular subpopulations, hematopoietic and endothelial pr ogenitor cells. CD34+ progenitor cells are suitable for a series of studies for directed di fferentiation into more committed types of blood cells and endothelial lineages. Immediately after isolation, the freshly prepared CD34+ progenitor cells are cryopreserved using a serum-free freezing medium. Each vial contains more than 100,000 cells per vial.

    Hepatic stellate cells (HSCs; also called vitamin A-storing cells, lipocytes, interstitial cells, fat-storing cell, Ito cells) exist in the space between parenchymal cells and sinusoidal endothelial cells of the hepatic lobule. Stellate cells store 80% of vitamin A in the whole body as retinyl palmitate in lipid droplets in the cytoplasm and are responsible for Vitamin A homeostasis. Stellate cells are present in extra hepatic organs such as the pancreas, lung, kidney, intestine, spleen, adrenal gland, ductus deferens and vocal cords. Stellate cells of liver and pancreas and have been described in all vertebrates ranging from lampreys (primitive fish) to humans, demonstrating their major importance.

    HUVEC are isolated from the vein of the umbilical cord and are commonly used for physiological and pharmacological investigations, such as macromolecule transport, blood coagulation, angiogenesis, and fibrinolysis. Human umbilical vein endothelial cells (HUVECs) have played a major role as a model system for the study of the regulation of endothelial cell function and the role of the endothelium in the response of the blood vessel wall to stretch, shear forces, and the development of atherosclerotic plaques.
  • Renal Proximal Convoluted Tubule Epithelial Cells (pdf)
    Renal proximal tubule cells play an important role in renal function. They reabsorb nearly all of the glucose and amino acids in the glomerular filtrate, while allowing ot her substances of no nutritional value to be excreted. They are also a major site of injury in a variety of congenital, metabolic, and inflammatory diseases with Polycystic kidney disease being one of the more important diseases. Proximal tubule cells can produce inflammatory mediators such as cytokines and chemokines and actively participate in acute inflammatory processes by affecting and directing leukocyte chemotaxis via the production of IL-8. Proximal tubule cells express IL-2R alpha and MHC class II antigens during inflammation after renal transplantation or in cresentic glomerulonephritis indicating the capacity to participate in pathogenesis of immune renal injury.
