- Gangrene
- A complication of necrosis (cell death) characterized by the decay of body tissues, which become black (and/or green) and malodorous. It is caused by infection or ischemia.
- Glycosaminoglycan
- Long linear highly charged polysaccharide composed of a repeating pair of sugars. Mainly found linked to a protein core in extracellular matrix proteoglycans, such as hyaluronic acid.
- Glycoprotein
- A protein, which has attached branching carbohydrates. Many plasma membrane proteins are glycoproteins and these may function in cell-cell recognition, such as in human blood groups and immune system response.
- Golgi complex
- Membrane-bounded organelle in eucaryotic cells where the proteins and lipids made in the endoplasmic reticulum are modified and sorted. Also referred to as Golgi apparatus.
- Gram-negative
- Bacteria that stain red with Gram's stain, e.g. Escherichia coli (survive under wet conditions).
- Gram-positive
- Bacteria that stain blue with Gram's stain, e.g. Staphylococcus aureus (survive under dry conditions).
- Granulation
- The bright red tissue formed from new capillary loops during the proliferative phase of healing.
- Ground substance
- A term that is often used for the gel-like water containing polysaccharides and proteoglycans in the extracellular matrix.
- Growth factors
- Growth factors are a subset of cytokines, cell signals, which have a number off functions including regulation and coordination of cell and tissue growth and development, and processes such as wound healing. There are numerous different growth factors with different functions, which have the potential to enhance wound healing through several mechanisms (see wound healing module). Examples of growth factors involved in wound healing are EGF (epidermal growth factor), PDGF (platelet-derived GF), FGF (fibroblast GF). See also Cytokines.
