High Content Screening Analysis to Evaluate the Toxicological Effects of Harmful and Potentially Harmful Constituents (HPHC)

12.7K
The objective of the study was to assess the biological impact of 15 cigarette smoke constituents using a combination of an impedance-based real time cell analyzer and a high-content screening (HCS)-based platform for toxicological assessment in vitro. This study provides information on effective doses, toxicity and modes of action of the tested compounds.

Preventing the Spread of Malaria and Dengue Fever Using Genetically Modified Mosquitoes

12.9K
In this candid interview, Anthony A. James explains how mosquito genetics can be exploited to control malaria and dengue transmission. Population replacement strategy, the idea that transgenic mosquitoes can be released into the wild to control disease transmission, is introduced as well as the concept of genetic drive and the design criterion for an effective genetic drive system. The ethical considerations of releasing genetically-modified organisms into the wild are also...

Resumen
Este resumen es generado por máquina.

Desarrollamos Microwell-seq, una plataforma rentable para la secuenciación de ARN de una sola célula (scRNA-seq), para crear un atlas de células de ratón (MCA). Este recurso mapea más de 400.000 células, revelando nuevas jerarquías celulares y permitiendo una definición precisa del tipo de célula.

Área de la Ciencia:

  • La genómica
  • Biología celular
  • La bioinformática

Sus antecedentes:

  • La secuenciación de ARN de una sola célula (scRNA-seq) está revolucionando la clasificación del tipo de célula.
  • Un atlas completo de una sola célula para sistemas complejos de mamíferos sigue siendo difícil de alcanzar.
  • Los métodos existentes de scRNA-seq pueden ser costosos y menos accesibles.

Objetivo del estudio:

  • Desarrollar una plataforma scRNA-seq de alto rendimiento y bajo costo (Microwell-seq).
  • Construir un atlas fundamental de células de ratón (MCA) que cubra los órganos principales.
  • Establecer una tubería computacional para la identificación del tipo de célula utilizando datos de expresión génica digital.

Principales métodos:

  • Desarrollo de la plataforma Microwell-seq utilizando dispositivos sencillos y baratos.
  • Análisis de más de 400.000 células individuales de diversos tejidos de ratón.
  • Creación de un canal de análisis basado en la web para datos de expresión digital de una sola célula.

Principales resultados:

  • Generación exitosa de un conjunto de datos de una sola célula a gran escala para el ratón.
  • Identificación de nuevas jerarquías unicelulares en tejidos no caracterizados anteriormente.
