Hepatocyte growth factor (HGF) is a potent mitogen for hepatocytes and a variety of other cells, including endothelial and epithelial cells, melanocytes, and keratinocytes.It also mediates epithelial morphogenesis.

To measure the distance, you can measure your foot and use it as a measuring tool, get a tape measure and use that, or trot your horse around one time and place the poles between where you see the hoof prints.

This shift is always less than one arcsec for any star, which is very small (where a circle is 360 degrees, one degree is 60 arcminutes, one arcminute is 60 arcsecs). The parallax of a star is used to calculate its distance. The angle of the parallax, Î¸, in arcsecs is equal to the distance, D, by the following formula: D = 1/Î¸. here the distance, D, is measured in parsecs, where one parsec equals 3.26 light-years (the distance travels in one year).
