âExtracorporeal membrane oxygenation (ECMO) or extracorporeal life support (ECLS) is a cardiopulmonary bypass technique. It provides long-term cardiac or respiratory support in patients with respiratory or cardiac insufficiency. Physicians often use this technology with newborns.
In biology, the extracellular matrix (ECM) is a collection of extracellular molecules secreted by cells that provides structural and biochemical support to the surrounding cells.he components of the glycoprotein matrix help cell walls of adjacent plant cells to bind to each other. The selective permeability of the cell wall is chiefly governed by pectins in the glycoprotein matrix. Plasmodesmata (singular: plasmodesma) are pores that traverse the cell walls of adjacent plant cells.
