Abstract
In determining the effectiveness of parameters on cells, after treatment of the cells with one or more selected parameters, the results of the treatment can be quickly determined by measuring the number n.sub.0 of cells having a predetermined cell form, subsequently mechanically stressing the cells for a sufficient period of time t to change the cell form substantially, thereafter again measuring the number n of cells having the predetermined cell form, and determining the cell viability .tau.defined by .tau.=t/1n(n.sub.0 /n).
