Allelic Composition Genetic Background
Chp1em1(IMPC)Tcp/Chp1em1(IMPC)Tcp embryos are developmentally delayed, show abnormal allantois and fragile allantois attachment, impaired embryo turning, abnormal head shape with failed cranial neural tube closure, abnormal heart development, and yolk sac defects.Chp1em1(IMPC)Tcp/Chp1em1(IMPC)TcpC57BL/6NCrl-Chp1em1(IMPC)Tcp/TcpMmucd
Chp1em1(IMPC)Tcp/Chp1em1(IMPC)Tcp placenta shows a diminished spongiotrophoblast layer, impaired chorioallantoic attachment, multiple labyrinth zone defects, and impaired chorioallantoic branching.Chp1em1(IMPC)Tcp/Chp1em1(IMPC)TcpC57BL/6NCrl-Chp1em1(IMPC)Tcp/TcpMmucd
Chp1em1(IMPC)Tcp/Chp1em1(IMPC)Tcp embryos show delayed development at E8.5.Chp1em1(IMPC)Tcp/Chp1em1(IMPC)TcpC57BL/6NCrl-Chp1em1(IMPC)Tcp/TcpMmucd
By E9.5, AlleleSymbol(MGI:6388376|0)/Chp1em1(IMPC)Tcp embryos are all severely dysmorphic and smaller despite normal neural tube patterning and presence of all 3 germ layers.Chp1em1(IMPC)Tcp/Chp1em1(IMPC)TcpC57BL/6NCrl-Chp1em1(IMPC)Tcp/TcpMmucd
