Isolation of different cell types from one sample by fluorescence activated cell sorting is standard but expensive and time consuming. Magnetic separation is more cost effective and faster by but requires substantial effort. An innovative pluriBead-cascade cell isolation system (pluriSelect GmbH, Leipzig, Germany) simultaneously separates two or more different cell types. It is based on antibod...

The catenin p120 is involved in many processes, including cell-cell adhesion and cancer. Recent work explores whether p120 independently regulates two key binding partners, RhoGTPase and cadherin.

Three studies by Danielson et al. (2017), GoodSmith et al. (2017), and Sensai and Buzsáki (2017) distinguish in vivo firing properties of dentate mossy cells from granule cells during behavior. Robust spatial remapping of mossy cells, in contrast to sparse firing of granule cells, suggests differential involvement in pattern separation.

Proper centrosome separation is a prerequisite for positioning the bipolar spindle. Although studies demonstrate that microtubules (MTs) and their associated motors drive centrosome separation [1], the role of actin in centrosome separation remains less clear. Studies in tissue culture cells indicate that actin- and myosin-based cortical flow is primarily responsible for driving late centrosome...

anxiety is one common disorder during childhood. in curing anxiety disorders, there are different types of psychological remedies, pharmotherapy, family therapy, and music therapy that can improve the individual’s anxiety, but we need some other remedies to improve social and emotional relationship and interactions. considering the importance of curing the anxiety disorders, the effect of sand ...

It has been unclear how cells complete cell division and resolve membrane connections to bring about cell separation. Recent work has shown that targeted secretion to the midbody is required to complete cell division.

This paper addresses the issue of cell loss and its consequent effect on video quality in a packet video system, and examines possible compensative measures. In the system's enconder, adaptive spectral separation is used to develop a two-layer coding scheme comprising a high priority layer to carry essential video data and a low priority layer with data to enhance the video image. A two-step er...

Background Sperm preparation before assisted reproductive techniques is very important for obtaining successful fertilization and pregnancy. During ICSI technique, sperms are selected based on viability and morphology. But this selection did not guarantee integrity of sperm DNA. Therefore, novel sperm selection procedures are introduced for selection of sperm with low DNA damage. One of these p...

Dictyostelium has played an important role in unraveling the pathways that control cell movement and chemotaxis. Recent studies have started to elucidate the pathways that control cell sorting, morphogenesis, and the establishment of spatial patterning in this system. In doing so, they provide new insights into how cell movements within a multicellular organism are regulated and the importance ...

Within epithelial tissue, cells are held together by specialized lateral junctions. At particular stages of development and in pathological processes such as metastasis, cells break down the intercellular junctions, separate from the epithelial sheet and migrate individually. Despite the importance of these processes, little is understood about the regulatory mechanisms of active cell separatio...
