Background:

Tissue identification is crucial for crime scene reconstruction but challenging with conventional methods.
Current bulk analysis methods lack sensitivity and accuracy for complex tissue mixtures.
Single-cell RNA sequencing (scRNA-Seq) offers a promising approach for enhanced cell and tissue identification.

Purpose of the Study:

Develop a sensitive, general-purpose single-cell annotation pipeline, scTissueID.
Accurately evaluate single-cell profile quality and determine cell/tissue types from scRNA profiles.
Improve accuracy and efficiency in cell and tissue identification for forensic and biomedical applications.

Main Methods:

Developed scTissueID, a novel single-cell annotation pipeline.
Incorporated a unique reference cell quality differentiation phase.
Validated performance against 8 state-of-the-art pipelines and 6 machine learning algorithms using forensic and Human Cell Atlas data.

Main Results:

scTissueID demonstrated superior and consistent performance in cell and tissue type determination.
The pipeline accurately evaluates single-cell profile quality.
Highlighted the critical role of cell quality differentiation in improving annotation accuracy.

Conclusions:

scTissueID provides an accurate and efficient tool for cell and tissue identification.
The pipeline significantly enhances forensic investigations by improving tissue analysis.
Offers broad applicability for various biomedical research endeavors requiring precise cell typing.
