Mapping mouse hemangioblast maturation from headfold stages

Mapping mouse hemangioblast maturation from headfold stages.

The mouse posterior primitive streak at neural plate/headfold stages (NP/HF, ~7.5 dpc-8 dpc) represents an optimal window from which hemangioblasts can be isolated. We performed immunohistochemistry on this domain using established monoclonal antibodies for proteins that affect blood and endothelial fates. We demonstrate that HoxB4 and GATA1 are the first set of markers that segregate independe...

Meiotic maturation of mouse oocytes in vitro: inhibition of maturation at specific stages of nuclear progression.

In vitro studies of meiotic maturation of mouse oocytes have been carried out in the presence of several drugs. The individual steps of nuclear progression, including dissolution of the nuclear (germinal vesicle) membrane, condensation of dictyate chromatin into compact bivalents, formation of the first metaphase spindle, and extrusion of the first polar body, are each susceptible to one or mor...

Third Molar Maturation Stages in Correlation with Cervical Vertebra Maturation Stages in a Saudi Sample

The orthodontic treatment is most favorable and effective during growth and hence the assessment of growth is significant in treatment planning for dental and maxillofacial malocclusion [1,2]. Several features such as body height, weight and sexual characteristics, dental and skeletal development are used to evaluate the pubertal growth. The stage of tooth maturation can determine the dental ma...

Mapping brain maturation.

Human brain maturation is a complex, lifelong process that can now be examined in detail using neuroimaging techniques. Ongoing projects scan subjects longitudinally with structural magnetic resonance imaging (MRI), enabling the time-course and anatomical sequence of development to be reconstructed. Here, we review recent progress on imaging studies of development. We focus on cortical and subc...
