Which type of cues is essential for harvested cells to form healthy tissues?

The formation of healthy tissues from harvested cells relies on a combination of structural, chemical, and mechanical cues. Each of these types of cues plays a critical role in guiding the behavior and function of the cells as they reorganize and form tissue.

Structural cues provide the physical architecture that cells need to adhere, migrate, and differentiate. The three-dimensional arrangement of the extracellular matrix (ECM) influences how cells interact and how they form connections. Without a proper structural framework, cells may not be able to organize correctly or perform their intended functions.

Chemical cues, including growth factors, hormones, and signaling molecules, provide information that directs cellular activities such as proliferation and differentiation. These biochemical signals are crucial for indicating to the cells what type of tissue they should become and how they should respond to their environment.

Mechanical cues relate to the physical forces and stability in their environment. Cells can sense mechanical properties such as stiffness and the strain that occurs during tissue formation. This mechanical environment greatly influences cellular behavior, including how they migrate, adapt, and organize into the required tissue structure.

Since healthy tissue formation is a complex process that requires the influence of all these cues to ensure that cells differentiate appropriately, adhere correctly, and function well, identifying "all of the above" is essential
