In vitro study of cell differentiation by two type mouse embryo stem cells on mono- and multilayer nanocarbon tubes
The effects of nanomaterials on human reproduction and development remain unknown. The risks of nanomaterials for future generations should be elucidated. Thus, it is important to establish an experimental method to accurately examine embryotoxicity. We previously investigated the myocardial cell differentiation of ES-D3 cells using monolayer (SWCNTs) and multilayer (MWCNTs) nanocarbon tubes. As a result, in spite of having the same carbon composition, the effects on the cell differentiation levels differed between the tubes. We investigated their cell differentiation and cytotoxic effects on EL M3 and ES-R1-EGFP B2/EGFP cells, which require feeder cells. As a result, myocardial pulse rates differed between the presence of SWCNTs and MWCNTs even when feeder cells existed between the samples and cells. The different surface structures of SWCNTs and MWCNTs may have influenced ES cell differentiation. (C) 2012 Elsevier B. V. All rights reserved.
