Email. The cartilage and bones form a supporting framework for the body. The ability to construct whole organs for therapeutic use remains a daunting challenge, requiring billions of cells to be rapidly organized into functional microarchitected units that are supplied with nutrients via pervasive vascular channels ().Without a readily perfusable circulatory network, engineered human tissues are limited to several hundred micrometers in thickness (2-10). There's considerable excitement that 3D printing technology might one day allow scientists to produce fully functional replacement organs from one's own cells. Types of Tissue in Digestive System: Muscular Tissue - Lines organs, expands and contracts to push food. Tissue engineering is distinguished from cell biology by the focus on the emergent function that arises from the organization of large numbers of cells into higher-order structures, variously called tissues or organs, depending on the level of anatomical complexity and structural integration. Recent works have demonstrated the need to better understand the in-vitro and in-situ processes during tissue formation, in order to regenerate complex, functional organs with desired cellular organization and tissue architecture. An organ is made of several types of tissue and therefore several types of cells Cells Often thought of as the smallest unit of a living organism, a cell is made up of many even smaller parts, each with its own function.
