Fig. 6From: A differential response to newt regeneration extract by C2C12 and primary mammalian muscle cellsp21 expression is downregulated by treatment with newt extract (see also Table 1). In control cells, p21 expression is seen in myoblasts, as they exit the cell cycle, and in MHC-expressing myocytes. In extract-treated cultures, the extensive p21 expression in mononucleated cells appears to be lost. However, larger myotubes retain p21 expressionBack to article page
