Kinetin Delays the Onset of Aging Characteristics in Human Fibroblasts

Rattan, S.I.S., Clark, B.F.C.·1994·Biochemical and Biophysical Research Communications

Abstract

Kinetin (Kn) is a synthetic cytokinin plant growth hormone having some senescence-retarding effects in plants. Its effects on animal cells have been, until now, best considered as growth inhibitory and anti-tumorigenic. However, we have observed that an addition of 40-200 microM Kn in the culture medium of human diploid fibroblasts can both delay the onset and decrease the extent of many of the ageing characteristics that appear during serial passaging of normal cells in culture. Age-related changes that are affected by Kn include morphological alterations, growth rates, cell size, cytoskeletal organisation, macromolecular synthesis and the intensity of autofluorescence due to the oxidative damage product lipofuscin. These anti-ageing effects of Kn are achieved without any increase in the cell culture lifespan in terms of maximum proliferative capacity in vitro.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
