Secretome of Olfactory Mucosa Mesenchymal Stem Cell, a Multiple Potential Stem Cell

Figure 7

Molecular functions and biological processes of extracellular proteins identified in OM-MSC conditioned medium. The molecular functions of the identified secreted proteins were composed of several categories, such as antioxidant activity, binding, catalytic activity, enzyme regulator activity, receptor activity, signal transducer activity, structural molecule activity, and transporter activity (a). It indicated that the main functions of secreted proteins are maintaining the homeostasis of extracellular matrix, transmitting signals, and so on. Significantly higher frequencies of genes () were associated with 16 biological processes (b). These proteins were most frequently involved in metabolism, defense response, signaling, and tissue differentiation.
