At just two - and - a - half hours old , a teensy yield - fly ball embryo is bustling with action , and now researchers have captured this developing in a 3D video present a young fertilized egg grow into a 20 - minute - old larva .
" This TV showsa fruit aviate embryofrom when it was about two - and - a - half hours old until it walk aside from the microscope as a larva , 20 hours later , " Lars Hufnagel , from the European Molecular Biology Laboratory ( EMBL ) in Heidelberg , Germany , state in a statement . " It shows all the hallmarks of yield - flyembryonic developmentin three dimensions . "
A fruit-fly embryo at just over an hour old.
The video reveals what looks like a bloblike being covered with diminutive projections , which are in reality various prison cell and cell parts , move across its body . For example , the cell on the embryo ’s belly dive inward to form the so - called adaxial furrow , or an pitting that results in the geological formation of a tube inside the embryo mark the starting line of the gastrulation stage of development ; other cells move around the embryo ’s rear end to its back in a cognitive process call convergent elongation . after in the video , an hatchway appear on the embryo ’s back before hem in jail cell shut this gap ( a cognitive process called dorsal stoppage ) .

The young microscope , called Multi - View SPIM ( MuVi - SPIM ) shines a flimsy sheet of light on the embryo , illuminating one layer of the embryo at a time to forestall light damage . It take four full epitome from unlike angles , which signify scientist do n’t have to rotate the sampling . The range are then flux to create a three - dimensional feeling at the sample , in this case a fruit - fly embryo . This whole process takes just seconds , so the microscope can repeat the process quickly .
As such , the different images that make up the video are taken in such speedy succession that very little has changed in the embryo from one frame to the next ; in that way , scientists can be sure of the location of each cell , or even structures inside cells , and track it throughout the video .
In this new subject area , detail this calendar week in the diary Nature Methods , Hufnagel and colleagues recorded the motion of every cell nucleus inthe embryonot only during the later developmental stages , but also throughout the first three hour ofthe embryo ’s life , when nuclei divide very rapidly .
In the futurity , the scientist hope to use their new microscope to investigate how pipe organ and tissues shape in the fruit fly and other organism .
