Ex Vivo Expansão e Manipulação Genética de Células-Tronco Hematopoéticas de Camundongos em Culturas à Base de Álcool Polivinílico

Overview

This protocol presents a method for the expansion and genetic manipulation of functional mouse hematopoietic stem cells (HSCs) using an ex vivo polyvinyl alcohol-based culture system. It allows researchers to explore hematopoiesis and provides a versatile platform for genetic and biochemical studies.

Key Study Components

Research Area

• Hematopoietic stem cell biology
• Hematopoiesis
• Gene editing techniques

Background

• The study enhances understanding of HSC functions and genetic manipulation.
• Long-term culture of HSCs supports detailed biological investigations.
