Kronos scRT

Kronos scRT performs single-cell replication timing analysis to determine cell-type-specific order of genome replication and its relationship to transcription and chromatin organization.

Key Features:

• Platform independence: Operates on asynchronous cell datasets without requiring cell sorting.
• scWGS support: Processes single-cell whole-genome sequencing (scWGS) data, including droplet-based scWGS.
• Large-dataset compatibility: Scales to analyze thousands of single cells from human and mouse cell lines.
• Single-cell resolution: Provides per-cell replication timing information to observe cell-to-cell variation during S phase.
• Population analysis: Analyzes both homogeneous and heterogeneous cell populations.

Scientific Applications:

• Replication–transcription–chromatin relationships: Investigates correlations between replication timing, transcriptional activity, and chromatin organization across cell types.
• Developmental biology: Studies replication timing dynamics during development at single-cell resolution.
• Cancer research: Examines replication timing variability and heterogeneity in cancer cell populations.
• Stem cell studies: Characterizes replication timing patterns and heterogeneity in stem cell populations.

Methodology:

Analyzes published datasets alongside droplet-based single-cell whole-genome sequencing (scWGS) data generated in the study to compute replication timing across thousands of cells and assess consistency and stochastic variation across S phase.
