5 major types of cells present in this tissue are:Adipocytes: These cells accumulate fat and serve as a reservoir of energy, and help in regulating energy metabolism.Mast Cells: These cells trigger immune and allergic responses by releasing substances like histamines. They also release chemoattractants into the surrounding.Mesenchymal Stem Cells: They help in the production of new fibroblasts and blood vessels.Fibroblasts: These help in synthesising ground substances, anchor and strengthen extracellular matrix, and also help in the repairment of tissues.Macrophages: They perform phagocytosis and destroy foreign pathogens.
