True or false? Collagen is the most abundant protein in the ECM.

Collagen is indeed the most abundant protein found in the extracellular matrix (ECM) of various tissues in the body. It serves as a primary structural component, providing strength, support, and elasticity to tissues. The ECM plays a crucial role in cellular functions such as adhesion, migration, and differentiation, and collagen is a key player in that functionality.

Collagen exists in various forms and types, each adapted to specific roles in different tissues, such as bone, skin, cartilage, and tendons. The presence of collagen helps to maintain the integrity and organization of these tissues, making it essential for overall structural support. This foundational role confirms that the statement regarding collagen being the most abundant protein in the ECM is true.
