The mesenchymals stem cells (MSCs) are cells with the great potential of differentiation are being introduced in the clinic for treatment of several diseases. Mesenchymal stem cells have several advantages including the stability of their phenotype in vitro. BACKGROUND: isolation of MSCs in amniotic fluid, its expansion and the demonstration of the capacity of these cells to differentiate in adipogenic and miogenic cells, without to change the chromosomal stability of the MSCs in culture. METHODS: in order to evaluate the functional change of these cells, were gotten values of the differentiated adipogenic cells and not differentiated through the dosage of triglycerides. The miogenic nature of the differentiated cells was analyzed comparing the creatine kinase - CK, lactic dehydrogenase - LDH and aldolase produced by the cells. RESULTS: the values of triglycerides were significantly higher in differentiated cells, showing intracitoplasmatic granule form after differentiation. All the biochemical characters were significantly higher in differentiated miogenic cells. CONCLUSIONS: this study suggests that the standardized protocol of differentiation can be used in the attainment of cells with characteristics of adipogenic and muscular cells, from amniotic fluid.
