Treatment of 10T1/2 cells with promoting phorbol ester drasticly enhanced migration studied fibroblasts in a serum-supplemented medium.The same cells when exposed to ionomycin or TPA in a serum-free medium did not show any migration.The addition of 1% of serum induced spontaneous and TPA stimulated migration.Also EGF and PDGE separatly or together induced the migration of 10T1/2 cells.Parallel studies of protein kinase C documented low enzymatic activity after treatment with TPA, whereas transcripts of PKC were shown independently of TPA treatment.
