Heterochromatin staining pattern of quall-chicken hybrid lymphocytes

Abstract

Feulgen-Rossenbeck staining of lymphoid cells of quail-chicken hybrids in histologic sections revealed a pattern of heterochromatin arrangement distinguishable from that of either parental type. During interphase, hybrid lymphocytes exhibited combined characteristics of both the parental quail and the parental chicken. Hybrid heterochromatin was arranged in a large central mass as in the quail and in fairly evenly distributed small chromacenters around the periphery of the nucleus similar to the arrangement in the chicken. It is suggested that this pattern of staining can be used as a marker for hybrid cells in studies of genetic interactions.

Comparative Analysis of <italic>Nkx2-5/GATA4/TBX5</italic> Expression in Chicken, Quail and Chicken-quail Hybrids during the Early Stage of Cardiac Development in Embryos

“…To our knowledge, little is known on the molecular mechanism of cardiac development in quail embryos, although there are a few publications on the morphology of cardiac development and even a comparison was made with chicken (Virágh et al, 1993; Saber et al, 2008). Chicken-quail hybrids were produced as early as the 1980s by artificial insemination of chicken sperm to quail (Taksashima et al, 1982; Greenfield et al, 1986). As an interspecies hybrid, it has a significant heterosis for growth rate, body size, meat quality and other production performances (Lucottehttp://www.sciencedirect.com/science/article/pii/0305049177900347 - AFF1#AFF1 et al, 1977; Liao et al, 2012).…”
