Gingival and Scleral Fibroblasts Fibroblasts are a spindle-shaped cell present in the connective tissue of the body. Their main function is to produce elements of the extracellular matrix, a tissue…
The Circulatory System: The Blood Delivery System The circulatory system delivers the blood and oxygen that all tissues of the body require for normal operation. In particular, the arteries, veins,…
The Airway Epithelium and Damage from Smoking Every time we take a breath, the epithelial cells that line the airway and lungs are exposed to potential pollutants in the air.…
Adult Stem Cells: A Critical Factor in the Maintenance of Adult Tissues Adult stem cells are capable of self-renewal and multipotent differentiation (differentiation into multiple, but limited, cell types). In…
The ultimate goal of culturing cells in vitro is to create a model system that mimics the in vivo environment as much as possible. Perhaps the most important part of…
A Recap of Lifeline® Products in 2019 It’s that time of year again! As you are winding down 2019 and preparing for 2020, don’t forget to check out the Lifeline®…
Fibroblasts and Wound Healing Fibroblasts are located in the connective tissue and produce the extracellular matrix, a supportive network that surrounds various cell types throughout the body. In addition to…
Smooth Muscle Cell Function Smooth muscle cells (SMCs) are specialized cells found especially in hollow organs with contractile function like the arteries and bladder. Contraction and relaxation of SMCs regulates…
The Excretory System and Diabetes The excretory system consists of the kidneys and urinary tract, which together, filter and eliminate waste from the body. As blood circulates throughout the body,…
Endothelial Cells and Peripheral Arterial Disease Endothelial cells comprise the innermost later of blood vessels, forming a barrier between the circulating blood and the tissues of the body. In particular,…
The Female Reproductive System The female reproductive system produces the female gametes, or germ cells, called eggs. Once fertilized by a sperm cell, the male gamete, the resultant zygote develops…
Bladder Anatomy and Function The bladder is responsible for collecting and storing the urine produced by the kidneys until it is voided from the body during urination. The inner epithelial…
The prostate is a walnut-shaped male organ responsible for secreting prostatic fluid, which is an important component of seminal fluid. This year, the American Cancer Society estimates that 31,620 men…
Multipotent, Pluripotent, and Totipotent Stem Cells and Induced Pluripotent Stem Cells Stem cells are undifferentiated cells that have two characteristics: they give rise to different mature cell types and have…
Keratinocytes: The Key Supporter of the Skin Barrier Keratinocytes are the most common cell type of the skin. They are present in the epidermis, which is the outermost layer of…
Endothelial Cells and the Extracellular Matrix (ECM) Endothelial cells line the vessels of the circulatory system and provide important support for vessel homeostasis, wound repair, and the inflammatory response. The…
Lifeline® Products in Research Studies in First Half of 2019 It’s that time again! Time for our mid-year review, where we look back on the last six months and review…
Small Airway Epithelial Cells The airway is lined by a layer of epithelial cells with multiple functions. In addition to providing a protective barrier function, the airway epithelium also secretes…
Function and Differentiation of Keratinocytes Keratinocytes make up the majority of cells in the epidermis, the outer layer of the skin. The progenitor cells that give rise to keratinocytes are…
Melanoma: Causes and Prevention Melanoma is a type of skin cancer that arises from melanocytes, the pigmented cell type of the skin found in the outer layer of the skin…
