The investigation of the human lung and its diseases is an important issue for drug development processes, although it is hampered by the availability of suitable in vitro models.

Studying the absorption and toxicity of inhaled drugs or chemicals requires a model reflecting the essential features of the air-blood barrier.

Chondrocytes are the cells that form the cartilage. They produce and maintain the cartilaginous matrix, which consists mainly of collagen and proteoglycans.

Fibroblasts are the most common cells of mammalian connective tissue. InSCREENeX offers an immortalized fibroblast cell line (CI-huFIB) derived from human foreskin.

The endothelium is the thin layer of cells that lines the interior surface of blood vessels and lymphatic vessels, forming an interface between circulating blood or lymph in the lumen and the rest of the vessel wall.

Osteoblasts are responsible for bone formation. InSCREENeX offers human osteoblasts immortalized with the help of the CI-SCREEN technology.

The endothelium is the thin layer of cells that lines the interior surface of blood vessels and lymphatic vessels, forming an interface between circulating blood or lymph in the lumen and the rest of the vessel wall.

Thyroid epithelial cells (also known as follicular cells or thyrocytes) are the major cell type in the thyroid gland and are responsible for the production and secretion of thyroid hormones.
