Generation of Induced Pluripotent Stem Cells

Area of Science:

• Stem Cell Biology
• Reproductive Biology
• Genetics

Background:

• Induced pluripotent stem cells (iPSCs) are somatic cells reprogrammed to a pluripotent state.
• This reprogramming is achieved through the ectopic expression of specific embryonic transcription factors.
• iPSC technology is crucial for disease modeling and developing human disorder treatments.

Purpose of the Study:

• To provide researchers with background information on iPSCs.
• To detail methods for producing MEF-conditioned medium and preparing MEFs.
• To outline protocols for creating, culturing, and cryopreserving iPSCs.

Main Methods:

• Generating iPSCs via viral vector transduction of reprogramming factors.
• Preparing mitotically arrested mouse embryonic fibroblasts (MEFs).
• Producing MEF-conditioned medium for iPSC culture.
• Techniques for iPSC passaging and cryopreservation.

Main Results:

• Established methods for iPSC generation and maintenance are presented.
• The protocols have been validated in numerous global laboratories.
• The study acknowledges potential limitations with viral vector transduction for certain cell types.

Conclusions:

• The provided methods serve as a reliable starting point for iPSC research.
• Alternative methods for transcription factor delivery may be necessary for specific cell types.
• This chapter equips researchers with practical skills for iPSC utilization.
