Key result
8-methyltryptanthrin enhances stem cell differentiation into beating cardiomyocyte-like cells compared to control.
Why the study?
Enhancement of cardiac differentiation is critical to stem cell transplantation therapy for severe ischemic heart disease.
Population
P19CL6 mouse embryonal carcinoma cells
Comparison
1 μM 8-methyltryptanthrin vs 1% dimethyl sulfoxide or vehicle
Design
Preclinical cell culture study

Tryptanthrin derivatives may promote cardiomyocyte differentiation in vitro; hypothesis-generating and should not yet inform clinical stem cell therapy.
8-methyltryptanthrin successfully differentiates P19CL6 mouse embryonal carcinoma cells into spontaneously beating cardiomyocyte-like cells, suggesting potential utility in stem cell therapies for ischemic heart disease.
Seya et al. (2014) studied Severe ischemic heart disease. 8-methyltryptanthrin vs. 1% dimethyl sulfoxide (DMSO) was evaluated on Differentiation into beating cardiomyocyte-like cells (number and area of beating aggregates). A 1 μM concentration of 8-methyltryptanthrin significantly increased the differentiation of P19CL6 cells into spontaneously beating cardiomyocyte-like cells compared to 1% DMSO.
