Methods for lineage tracing on the organism-wide level

Area of Science:

• Developmental Biology
• Genomics
• Cell Biology

Background:

• Determining cell lineage origin is crucial for understanding development and diseases like cancer.
• Traditional lineage tracing methods include microscopy and genetic labeling.
• These methods have limitations in scale and multiplexing capacity.

Purpose of the Study:

• To review the emerging approach of using high-throughput sequencing data for lineage analysis.
• To highlight the potential of sequencing-based methods for large-scale lineage tracing.
• To discuss the integration of lineage analysis with single-cell RNA sequencing.

Main Methods:

• Review of existing literature on lineage tracing techniques.
• Focus on high-throughput sequencing-based lineage analysis.
• Discussion of complementary methods like inducible recombinases and fluorescent reporters.

Main Results:

• High-throughput sequencing enables lineage analysis of large cell numbers.
• This approach allows for organism-wide lineage tracing.
• Simultaneous transcription profiling via single-cell RNA sequencing is possible.

Conclusions:

• High-throughput sequencing represents a significant advancement in lineage tracing.
• This technology enhances multiplexing capacity for large-scale studies.
• It integrates lineage information with cellular identity through transcriptomics.
