Untersuchungen zum Problem der WachstumsregulationArchiv für Entwicklungsmechanik der Organismen - Tập 156 - Trang 1-19 - 1965
Heinz-Joachim Pohley
A growth-regulation-system is defined in mathematical terms in order to interpret the observed behavior of regenerating and growing imaginal disks of the wings inEphestia kühniella. It is assumed that the growth-rate of an imaginal disk depends upon two variables, a variablek which is interpreted as the concentration of the moulting hormone and a second variablez representing the size of the disk ...... hiện toàn bộ
An in vitro study of teratogenicity in the rat due to antibody-induced yolk sac dysfunctionArchiv für Entwicklungsmechanik der Organismen - Tập 195 - Trang 236-242 - 1986
Stuart John Freeman, Nigel Andrew Brown
An antiserum was prepared in rabbit against rat visceral yolk sac endoderm. The initial injection was of a ConA-Sepharose purified fraction of endoderm, and subsequent injections were of whole endoderm. The antiserum was found to be a potent rat teratogen in vivo, the most common defects observed being anophthalmia and hydrocephaly. Using rat whole embryo culture, the antiserum was demonstrated to...... hiện toàn bộ
kitb, a second zebrafish ortholog of mouse Kit Archiv für Entwicklungsmechanik der Organismen - Tập 215 - Trang 470-477 - 2005
Eve M. Mellgren, Stephen L. Johnson
The large numbers of duplicated pairs of genes in zebrafish compared to their mammalian counterparts has lead to the notion that expression of zebrafish co-orthologous pairs in some cases can together describe the expression of their mammalian counterpart. Here, we explore this notion by identification and analysis of a second zebrafish ortholog of the mammalian Kit receptor tyrosine kinase (kitb)...... hiện toàn bộ
