Figure 2

Diagrammatic model to present the interrelationship of the main components of skeletal muscle in beef cattle. The green arrow represents a stimulative effect. The yellow arrow represents a secretion process. The red “T” symbol represents an inhibitory effect. The shade of symbol represents the intensity of the corresponding biological function or process. The location of FAPs and pericytes, the nature of two types of pericytes and their fates, resources of ECM, genes related to the filling process of preadipocyte, as well as the effect of HGP treatment on the myogenic lineages are based on the published literature [12,17,30,31,33,65-71].
