The cell clinic: Closable microvials for single cell studies
نویسندگان
چکیده
We present the development of a cell clinic. This is a micromachined cavity, or microvial, that can be closed with a lid. The lid is activated by two polypyrrole/Au microactuators. Inside the microvials two Au electrodes have been placed in order to perform impedance studies on single or a small number of cells. We report on impedance measurements on Xenopus leavis melanophores. We could measure a change in the impedance upon cell spreading and identify intracellular events such as the aggregation of pigment granules. The electrical data is correlated to optical microscopy.

Background: One of the main problems in ART is low pregnancy rates. The factors involved in successful pregnancy include; 1. mother related factors such as the status of endometrial receptivity and hormonal status of the mother. 2. embryo related factors such as; number of transferred embryo, embryo scores including: number and size of the blastomeres, and their fragmentation. The aim of the pr...
متن کاملA Graph-Based Clustering Approach to Identify Cell Populations in Single-Cell RNA Sequencing Data
Introduction: The emergence of single-cell RNA-sequencing (scRNA-seq) technology has provided new information about the structure of cells, and provided data with very high resolution of the expression of different genes for each cell at a single time. One of the main uses of scRNA-seq is data clustering based on expressed genes, which sometimes leads to the detection of rare cell populations. ...

: World population has been continuously raised and therefore due to this fact new source of foods, particularly proteins, are in demand. In recent years, single cell protein has been considered as an accepted substitute for animal and plant proteins. In this study, single cell protein production was studied in a batch submerged culture using Aspergillus niger PTCC5012. Experimental design was ...
متن کاملIndium-111 maltolate complex as a cell labeling agent for SPECT imaging
Introduction: Due to the cell labeling potentials of various metal-maltol complexes, the idea of developing a possible cell labeling imaging agent using single photon emission computed chromatography (SPECT) with[111In]-maltolate complex has been investigated. Methods: [111In] labeled 3-hydroxy-2-methyl-4H-pyran-4-onate ([111In]-maltolate) was prepared using f...
