Cell cycling properties of LmnaDhe/+ fibroblasts.

1Means and standard deviations for cultures from three mice are reported.2Culture growth over four days measured by static adhesion assay.3Proportion of all cells positive for SA-β-gal fluorescence versus total cells counted by flow cytometry.4Cycling cells identified by Ki-67 immunostaining.5Apoptosis measured by Annexin V labeling and flow cytometry.6Mitotic indices determined from cells stained with anti-Lamin A and anti-α-Tubulin antibodies and DAPI.7p-values were computed using Student's t-test.
