Microtrabecular lattice of the cytoplasmic ground substance. Artifact or reality.

Microtrabecular lattice of the cytoplasmic ground substance. Artifact or reality

The cytoplasmic ground substance of cultured cells prepared for high voltage transmission electron microscopy (glutaraldehyde/osmium fixed, alcohol or acetone dehydrated, critical-point dried) consists of slender (3-6 nm Diam) strands--the microtrabeculae (55)--that form an irregular three-dimensional lattice (the microtrabecular lattice). The microtrabeculae interconnect the membranous and non...

“Porterplasm” and the microtrabecular lattice

JCB • VOLUME 170 • NUMBER 6 • 2005 864 " Porterplasm " and the microtrabecular lattice eith Porter was to many the father of biological electron microscopy (EM) and even of cell biology. He helped instigate the founding both of this journal and of the K American Society of Cell Biology, and was a key figure in defining the structures of intact and sectioned cells. The latter stages of Keith Por...

The cytoplasmic filament system in critical point-dried whole mounts and plastic-embedded sections

High voltage electron microscopy of intact cells prepared by the critical point drying (CPD) procedure has become an important tool in the study of three-dimensional relationships between cytoplasmic organelles. It has been claimed that critical point-dried specimens reveal a structure that is not visible in sections of plastic-embedded material; it has also been claimed that this structure, in...

Generation Gap: Illusion or Reality?

Values have very important functions in any society. The significance  becomes so clear when a society has been exposed to changes and strengthening social cohesion is viewed as an essential subject. Great changes as the Islamic Revolution and the Imposed War have been happened in Iran during last several decades. In this line, generations can be understood via  direct or indirect experience of...
