Both EGF and TGF were identified in the gastric mucosa and found to promote cell proliferation, mucosal repair, gastroprotection, and healing processes.

In chronic tendon injuries, mechanical loading has also been shown to stimulate fibroblast proliferation and collagen synthesis along with collagen realignment, all of which promote repair and remodeling.

In the PNS (Peripheral Nervous System), glial cells known as Schwann cells promote repair.

The probable cause of the derailment, the board officially concluded today, was the failure of top managers at the railroad "to foster an environment that promoted an adequate inspection, maintenance and repair."

The aim of this study was to investigate whether these nociceptive neurones strengthen mucosal defence against injury or promote rapid repair of the damaged mucosa, or both.

It has also been tested in patients with chronic neurotrophic corneal epithelial defects and found to promote repair.

Also, NGF appears to promote myelin repair.

Instead, for TGF-β1 gene therapy to be effective in promoting repair of damaged cartilage, the level of TGF-β1 will need to be highly regulated as well as expression localized.

Granulocytes destroy viruses and bacteria; macrophages do likewise, but also promote repair of tissues by removing dead and damaged cells, and have been shown to destroy tumor cells.

The Penn researchers have used gene therapy on these mice to produce increased levels of IGF-1, or insulinlike growth factor-1, a protein that promotes muscle growth and repair.
