红腹锦鸡胚胎期羽毛芽发育的研究
Development Characteristics of Feather Bud of Chrysolophus pictus in Embryonic Period
摘要
Abstract
The aims of the present study were to observe the histological structure of feather follicles of Chrysolophus pictus in embryonic period and its morphological changes, and to provide a histological base for the investigation of molecular regulation mechanism of Chrysolophus pictus feather follicles development. The development characteristics of Chrysolophus pictus embryos with 5, 7, 8, 9, 10, 11, 13, 16, 18-day embryonic ages were observed, respectively. The back skin of Chrysolophus pictus embryos with above-mentioned embryonic ages were collected respectively and were used to prepare paraffin sections which were subsequently stained using a standard HE staining method. The morphological structure of feather follicles was observed using an optical microscope. The feather buds development of Chrysolophus pictus embryo with 9-day embryonic age was initially observed, and the pigment deposition in feather follicles was found. In 16-day embryonic age, the development of feather follicles was basically completed, and the body surface of Chrysolophus pictus embryo was covered with feather. The results of the study may provide a histological base for clarifying the molecular regulation mechanism of feather development of Chrysolophus pictus.关键词
