regulates regulation of satellite cell activation involved in skeletal muscle regeneration Any process that modulates the frequency, rate or extent of satellite cell activation. The satellite cell activation is the process that initiates satellite cell division by causing it to move from quiescence to the G1 stage of the cell cycle. The cell swells and there are a number of other small changes. The cells then start to divide. Following cell division the cells will differentiate.
