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…
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 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…
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…
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 (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 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…
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…
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 (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…
Vascular smooth muscle cells (VSMCs) line blood vessels, providing a structural foundation and controlling vessel constriction and relaxation, which regulates blood flow and pressure. Vascular smooth muscle cell contraction is…
The skin is a multi-layered organ that covers the entire body and serves as a barrier to the outside environment. The outermost layer is called the epidermis and is composed…
Lifeline® offers a large number of primary cells for your research needs, many of which can be efficiently transfected. Importantly, Lifeline® cells can be used as normal control cells for…
Where do Human Airway Cells Come From? Oxygenated air enters through the mouth or nose and passes into the trachea. The trachea branches into two bronchi, which lead to…
The kidneys are an important component of the renal system. Blood is carried to the kidneys where waste products are filtered in structures called nephrons. Each nephron is composed of…
The Circulation System and Endothelial Cell Function A healthy circulation system is critical for normal physiological function; Arteries, veins, and, capillaries transverse the body providing an essential blood supply to…
Human Female Reproductive System The female reproductive system that supports the fertilization and growth of an embryo includes the vagina, ovaries, fallopian tubes and the uterus. These organs all have…
Human Male Reproductive System The male reproductive system includes external organs such as the penis and scrotum and internal organs such as the epididymis, vas deferens, and accessory glands (seminal…
Your skin is your strongest form of protection from a plethora of environmental insults. From bad weather, to pathogens, to UV exposure, to injury, skin is the barrier that not…
