Human Keratinocytes: First Line of Defense
Keratinocytes are the major cell type of the epidermis (the outermost skin layer) and are also found in the oral mucosa. They form the primary protective barrier between the internal…
Excretory System Epithelial Cells: Bladder and Renal Epithelial Cells
The excretory system processes the body’s waste and excretes waste as urine. The two kidneys filter waste products from the blood, creating urine. The urine is then passed from the…
Epithelial Cells — Guardians of the Internal Environment — and the Latest Cancer Studies
Epithelial cells line multiple organs throughout the body, including the gastrointestinal tract, bladder, uterus, and airway. Epithelial cells are arranged in sheets, each cell closely connected to its neighbors through…
Human Fibroblasts: a Multi-Faceted Cell Type
Fibroblasts are a type of mesenchymal cell most commonly found in the connective tissue of many organs, including the gastrointestinal tract, skin, bladder, uterus, and others. Fibroblasts produce connective tissue…
The Airway Epithelium: Barrier Against Foreign Pathogens
The human airway (including the trachea and bronchi) is lined by a single layer epithelium that serves as the interface between the external and internal environments. It also provides a…
Smooth Muscle Cells in Atherosclerosis and the Latest Research
Smooth muscle cells (SMCs) are found in many organs, including the GI tract, uterus, bladder, and vasculature. In particular, vascular SMCs (VSMCs) are found within vessel walls, and their contractile…
Endothelial Cells and Cardiovascular Disease
Endothelial cells line the blood and lymphatic vessels of the body. They do much more than simply function as a lining, however. Endothelial cells are critical for maintenance of vessel…
Human Female Reproductive Cells — Research Uses and Latest Study

Lifeline® Normal Human Cells have been validated for numerous applications that cover diverse research interests . . . Cancer research. Many Lifeline® normal human cell types are used as normal…
Bladder Anatomy and the Latest Bladder Cancer Research Studies
Following its exit from the kidneys though the ureters, urine enters the bladder, a muscular organ that collects and expels urine through the urethra. The bladder epithelium, or urothelium, is…
Prostate Anatomy, Prostate Cancer, and the Latest Research
The prostate is a small gland that is part of the male reproductive system. It secretes fluid that is part of the semen. Columnar epithelial cells comprise the secretory epithelium,…
Smooth Muscle Cell Studies: The Force Behind Contraction
Smooth muscle cells (SMCs) reside in the outer layers of blood vessels and other contractile organs, including the bladder, uterus, respiratory tract, and gastrointestinal tract. SMCs contract involuntarily, and molecular…
Kidneys: The Body’s Filter – and How Renal Cells are Being Used in Cancer Research
The kidneys are part of the renal system, which is responsible for removing waste from the body. The kidneys have a primary role in filtering wastes from the blood, while…
Research Applications of Lifeline Cells and Culture Media
Many research groups have demonstrated the diversity of our many cell types. A few of the many research applications are highlighted here: Lifeline® Dermal Fibroblasts as normal, non-transformed control cells…
Mesenchymal Stem Cells: Cells with Multipotent Potential
Mesenchymal stem cells (MSCs) are an extremely useful tool to study stem cells and differentiation. MSCs can be isolated from a number of organ sites that include the bone marrow,…
Endothelial Cells: Master Regulators of Vascular Function
Endothelial cells line blood vessels and are crucial for maintaining proper vessel homeostasis and blood flow. They are essential for regulating thrombosis (blood clotting), vessel growth, and angiogenesis (formation of…
Gingival Structure, Function, and the Latest Research
The gingiva (or gums) is the tissue that surrounds and protects the teeth and underlying bone. The gingiva is attached to the tooth, forming a seal that protects the underlying…
Dermal Fibroblasts Used to Study Induced Pluripotent Stem Cells and UV Radiation
The skin is the body’s first level of defense against the external environment. It is composed of multiple tissue layers that are held together by connective tissue, which supports and…
Mesenchymal Stem Cells Latest Research Studies
Mesenchymal stem cells (MSCs) are stromal cells that are primarily found in the bone marrow, but can be isolated from other locations, including adipose, the umbilical cord as well as…
