Study Notes
Types of Healing
- There are two types of healing: regeneration and repair.
- Regeneration requires remaining cells to be capable of dividing and the collagen framework tissue to be intact.
- Cell nature and type are important for healing
Cell Types
- There are three types of cell types:
- Labile cells
- Stable cells
- Permanent cells
Regeneration
- Regeneration is the process of replacing damaged tissue with the same type of tissue
- It's possible in tissues with labile cells, like the skin and bone marrow.
Immature Granulation Tissue
- Immature granulation tissue is a type of connective tissue that forms during the healing process
- It is characterized by a high number of fibroblasts, collagen, and blood vessels.
- Immature granulation tissue is essential for wound healing as it provides a scaffold for new tissue formation and helps to fill the wound space.
- Over time, immature granulation tissue matures into scar tissue.
Healing
- There are two types of healing: regeneration and repair
- For regeneration to occur:
- Remaining cells must be capable of division
- The collagen framework tissue must be intact
- Cell nature and type are important for healing.
Cell Types
- There are three main cell types involved in healing:
- Labile cells - continuously dividing and regenerating
- Stable cells - normally in a quiescent state (not dividing) but can re-enter the cell cycle when needed
- Permanent cells - do not divide after birth
Regeneration
- Requires the remaining cells to be capable of dividing
- It requires that the framework of the tissue be intact
- Regeneration is ideal for healing
Immature Granulation Tissue
- Characterized by newly formed capillaries, fibroblasts, and inflammatory cells
- Plays a significant role in tissue repair, forming a foundation for new tissue development
- Eventually develops into scar tissue, which is less functional than the original tissue.
