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

B12 injections are also used to treat people with malabsorption (gastrointestinal conditions that prevent proper absorption of B12 from the gut), for example, people with atrophic gastritis (stomach inflammation) and intrinsic factor deficiency (pernicious anemia) or those who have undergone surgical procedures such as gastrectomy or small bowel resection (stomach or intestine removed), autoimmune diseases, etc
