Granulation tissue is the vascularized connective tissue that fills the wound bed during the proliferative phase of healing. Its key job is to provide a living scaffold for repair: fibroblasts lay down extracellular matrix, new capillaries grow in to supply blood, and inflammatory cells clean debris. This matrix supports epithelial cells as they migrate across the wound and enables wound contraction by myofibroblasts, promoting closure. Growth factors released by granulation tissue help coordinate healing, but initiating nerve regeneration is not its primary function; nerve regrowth depends more on Schwann cells and neurotrophic signaling. It isn’t a site for adipose storage either. So the best description is that granulation tissue provides a scaffold for repair and helps wound closure.
