Description
Abstract
A study was undertaken to analyze the
spatio-temporal pattern of mesenchymal cell
proliferation in the developing palate of quail. Quail
embyros were grown in shell-less culture. The
developing palates were labelled with 3~-thymidine
between culture days 2-6 (which corresponded in vivo
incubation days 5-9), and processed for light
microscopic autoradiography. Percent labelled
mesenchymal cells were determined. The data showed
that, as in mammals, a high rate of random cell
proliferation in mesenchyme was a major component of
early palate development in quail. As the palate
morphogenesis advanced, the rate of cell proliferation
declined. Segmental analysis, however, indicated that, in
contrast to mammals, the mesenchymal cell proliferation
rates continually changed in various regions of quail
palate during morphogenesis. It was suggested that the
spatio-temporal changes in the distribution of dividing
cells may reflect differences in the timings of cell cycles
between various segments, thus resulting in a
heterogeneous population of cells in the developing
palate of quail. Further, the differences in the segmental
pattern of cell proliferation between birds and mammals
may form the basis for differences in the morphogenesis
of their palates.
