Hepatocyte growth factor (HGF) is the only known growth factor that activates quiescent satellite cells in skeletal muscle.
Hepatocyte growth factor regulates cell growth, cell motility, and morphogenesis by activating a tyrosine kinase signaling cascade after binding to the proto-oncogenic c-Met receptor. Hepatocyte growth factor is secreted by mesenchymal cells and acts as a multi-functional cytokine on cells of mainly epithelial origin.
HGF, produced by some cancer cells, stimulates c-Met, through activation of the autocrine signaling system. Hepatocyte growth factor (HGF) is a paracrine hormone that plays an important role in epithelial-mesenchymal transition. HGF secreted by mesenchymal cells affects many properties of epithelial cells, such as proliferation, motility, and morphology.

The molecule produced by light reactions in plants and used by some bacteria for cellular respiration is oxygen. Photosynthesis occurs only in the light, whereas cellular respiration occurs in both the light and the dark. Complex organic molecules release energy during cellular respiration, but they store energy during photosynthesis.
The majority of autotrophs, or organisms that do not rely on external food sources, obtain the majority of their energy from light reactions. These organisms are known as photoautotrophs. When light is present, chemical reactions known as "light reactions" occur. Photosynthesis is the plant-based light-induced reaction.
This is the process of converting light energy into chemical energy. The sun's light energy is converted into the compounds ATP and NADPH during this process (nicotinamide adenine dinucleotide phosphate).
