Chromatin distribution pattern and cell functioning

Abstract

Chromatin distribution patterns of the nuclei of the follicular epithelial cell of Dendroctonus pseudotsugae Hopk. (Scolytidae: Coleoptera) were analyzed after creating their digital images. The five cell populations examined consisted of follicular epithelial cells at three different stages of structural and functional differentiation and two populations in which this differentiation was blocked. The results show that chromatin distribution patterns differ when cells are structurally and functionally different but are not different in cells that are structurally, developmentally, and functionally similar. The procedures are capable of detecting minute differences and appear useful for early detection of developmental and functional changes in relation to normal and pathological conditions.
