Structural analysis of the Pimelodus maculatus (Lacépède, 1803) embryogenesis (Siluriformes: Pimelodidae)

open access: yesNeotropical Ichthyology
The fish embryonic development comprises the events between the egg fertilization up to larvae hatching, being useful for the identification of viable eggs in productivity and survival studies as well as in raising experiments of several species.

Electroporation and in vitro culture of early rabbit embryos

open access: yesData in Brief, 2018
The functional interrogation of factors underlying early mammalian development is necessary for the understanding and amelioration of human health conditions. The associated article [1] reports on the molecular characterization of markers of neural crest

A deficiency in SUMOylation activity disrupts multiple pathways leading to neural tube and heart defects in Xenopus embryos

open access: yesBMC Genomics, 2019
Background Adenovirus protein, Gam1, triggers the proteolytic destruction of the E1 SUMO-activating enzyme. Microinjection of an empirically determined amount of Gam1 mRNA into one-cell Xenopus embryos can reduce SUMOylation activity to undetectable, but

Oxygen Consumption of the Parts of the Amphibian Gastrula.

open access: yesExperimental Biology and Medicine, 1939
Interest in the organizer has led to the determination of its oxygen consumption and the results of various investigators do not agree. Braehet,1 Braehet and Shapiro,2 and Fischer and Hartwig,3 agree that the dorsal lip exhibits a higher rate, while Waddington, Needham and Brachet,4 and Boell and Needham5 report that the rates of O2 consumption of the ...

Transcriptome Sequencing Reveals Dynamic Gene-Expression Profiles During Early Embryonic Development of Sichuan Taimen (Hucho bleekeri)

open access: yesFishes
The Sichuan taimen (Hucho bleekeri) is a flagship species for the Yangtze River and is classified as critically endangered by the IUCN. Successful artificial breeding and conservation efforts are therefore essential for maintaining population stability ...

Expanded expression of pro-neurogenic factor SoxB1 during larval development of gastropod Lymnaea stagnalis suggests preadaptation to prolonged neurogenesis in Mollusca

open access: yesFrontiers in Neuroscience
IntroductionThe remarkable diversity observed in the structure and development of the molluscan nervous system raises intriguing questions regarding the molecular mechanisms underlying neurogenesis in Mollusca. The expression of SoxB family transcription
