With the social and economic burden of lung diseases and medications on the rise, lung-on-a-chip model becomes a booming platform for identifying new and possible best therapeutics for individuals apart from an improvement of the health status of the patient. Creative Biolabs' lung-on-a-chip model is a micro-engineered cell culture device that replicates the 3D microarchitecture and microenvironment, breathing movements as well as primary physiological functions of the human lung. Our model will help you in investigating the physiology and disease etiology of human lungs, toxicological studies, and drug screening.
By using microfabrication to process microstructures of specific shapes on microchips composed of polydimethylsiloxane silicon or other high polymer materials, two upper and lower microfluidic channel structures are formed. The top channel is seeded with alveolar epithelial cells. While oxygen is given to make an air-liquid interface, fabricating the alveolar structure; the down channel includes vascular endothelial cells and is infused with culture medium, forming capillary channels and fluid shears. The middle platform is parted by a porous membrane to duplicate the alveolar septum. Side chambers are located on both sides of the organ chip that are linked to two vacuum pumps. By modifying the pressure of the side chambers, the porous membrane is stretched to imitating breathing movement. After this process, the cells form a functional tissue unit.
