PRP also restores damaged connective tissue by promoting the migration, proliferation and activation of fibroblasts.[15,16] Platelets also host a vast reservoir of over 800 proteins which when secreted act upon SCs, fibroblasts, osteoblasts and endothelial and epithelial cells.[12] The main purpose of using PRP for therapeutics originated from the idea to deliver the growth factors, cytokines and -granules to the site of injury, which acts as cell cycle regulators, and promote healing process across variety of tissues.[8] The PRP preparations are known to contain many growth factors, chemokines and cytokines [Figure 1] which induce the downstream signaling pathways that ultimately lead to synthesis of proteins necessary for collagen, osteoid and extracellular matrix formation.[17] PRP also has numerous cell adhesion molecules including fibrin, fibronectin, vitronectin and thrombospondin that trigger the assimilation of osteoblasts, fibroblasts and epithelial cells
In the case of eWAT, an increase in endogenous fatty acids following adherence to a HFD activates two sensors within adipocytes, Toll-like receptor 4(TLR4) and inflammasomes, which causes an influx of neutrophils to enter the eWAT, leading to increased levels of chemokine and cytokine expression (132)
