The chemotactic response of human gingival fibroblasts to platelet-derived growth factor (PDGF) was investigated in 48-well modified Boyden chambers. Results were quantified using computer-assisted image analysis of propidium iodidestained cells and were compared with results obtained using the conventional method of quantification by direct counting. Quantification by image analysis was found to be rapid and accurate, and correlated closely with results obtained by direct counting. Bromodeoxyuridine (BrdU)-labeled proliferating cells were double stained with propidium iodide and fluorescein isothiocyanate (FITC)-conjugated anti-BrdU antiserum. The cycling cells showed a markedly reduced chemotactic response to PDGF, whereas cells in S-phase of the cell cycle did not show any response. This method of quantification of results of Boyden chamber assays is simple and reliable, and allows the use of double labels to investigate the chemotactic response of subpopulations of cells within a heterogeneous population of cells.
