Regeneration results in the complete restitution of lost or damaged tissue; repair may restore some original structures but can cause structural derangements. 1. [1] [70] [71] Repair means incomplete regeneration . Modulation of the immune system can both help and hinder repair and regeneration. Differences i n collagen . The process of repair is generally employed when tissue framework is damaged as it is in deep wounds. A broad generalization is that the same or similar processes are involved in the early stages of life, and in life going on at all ages. The neonate mammalian immune system has impaired pro-inflammatory function, is prone to T-helper type 2 responses and has an immature adaptive immune system skewed towards regulatory T cells.

Cancers have been described as wounds that do not heal, suggesting that the two share common features. What’s the difference between regeneration and restoration? 3. The main difference between repair and regeneration is that repair is the restoration of tissue architecture and function after an injury whereas regeneration is a type of healing in which new growth completely restores portions of damaged tissue to their normal state. Repair responses following Injury/Inflammation 4. The histological differences between repair and regeneration in the MRL/MpJ mouse shown at two different time points during healing. • Repair of damaged tissues occurs by two types of reactions: regeneration by proliferation of residual (uninjured) cells and maturation of tissue stem cells • deposition of connective tissue to form a scar.
