sounds interesting! wish u good luck. ![]() you'd better have more discussion with biologists, especially with a developmental biology background or cell biology, to design a suitable but valuable model to study (cell type, influencing factor...) Here is one about nanotopographic influences: 1. McMurray, R. J.; Gadegaard, N.; Tsimbouri, P. M.; Burgess, K. V.; McNamara, L. E.; Tare, R.; Murawski, K.; Kingham, E.; Oreffo, R. O. C.; Dalby, M. J., Nanoscale surfaces for the long-term maintenance of mesenchymal stem cell phenotype and multipotency. Nat Mater 2011, 10, (8), 637-644. |

ATP analysis could be used to measured the loss in viability because a decrease in ATP production can be linked to a decrease in cell number. Specifically, ATP could be quantified by measuring the light produced through ATP's reaction with a naturally occurring firefly enzyme-Luciferase using a luminometer. The amount of light produced corresponds proportionally to the amount of live cells present in the sample. |

Are u using multipotent cells like hMSCs? if yes, you could try high-content imaging (see the proliferation) and immunofluorescence Staining (see the expression of alkaline phosphatase (ALP), a marker for early osteogenic differentiation) |

Thank you sir. So the name of this sort of analysis is ' the ATP analysis¡®? Are these reactions you mentioned? luciferin + ATP ¡ú luciferyl adenylate + PPi luciferyl adenylate + O2 ¡ú oxyluciferin + AMP + light But, are these reaction happening in every type of cell like fibroblasts and epithelials, which are likely to be used in my experiments according to articles in this field. |

during differentiation, multipotent stem cells could read their microenvironmental signals, integrate them intracellularly, and make varying decisions accordingly. E.g., mesenchymal stem cells, could differentiate into both fibroblasts and osteoblasts according to the matrix stiffness. These points help to explain the development of different tissues. Question: why do u perform these experiments? what is your novelty of your work? have u read some relevant literatures on this topic? As I know, it is generally not new. See the former work of Christopher Chen and Dennis Discher: Geometric Control of Cell Life and Death Science 30 May 1997: Vol. 276 no. 5317 pp. 1425-1428 D.E. Discher, P. Janmey, Y-L. Wang. Tissue cells feel and respond to the stiffness of their substrate. Science 310:1139-1143 (2005). |

Actually I am planning to bring down the surface topography to nano meter scale, to explore the details how surface structure affect cells. I have read couple dozens of articles, they observed the cells' attachment and proliferation on certain nano-patterns, but I have not looked into how surface structure affect stem cell differentiation. |
