Embryonic Stem Cells

Embryonic Stem Cells

Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Background:

Embryoid bodies (EBs) derived from embryonic stem cells (ESCs) are used in 3D differentiation to mimic early human development.
The fidelity of in vitro-derived cells to actual embryonic cells remains a key question.

Purpose of the Study:

To develop and present a deep learning (DL) framework for assessing the developmental accuracy of in vitro stem cell models.
To provide researchers with tools to classify and evaluate cell types generated in vitro.

Main Methods:

Leveraged single-cell RNA sequencing (scRNA-seq) data from early human development.
Employed scvi-tools for data integration and cell type classification.
Developed a DL model to assign cell identities and reliability scores (entropy) to in vitro cells.

Main Results:

Successfully integrated diverse scRNA-seq datasets to create a comprehensive model of early human development.
The DL tool accurately classifies in vitro cell types and quantifies classification confidence.
Publicly available DL models and protocols are provided for interrogating stem cell-derived embryo models.

Conclusions:

The developed DL tools offer a robust method for evaluating the developmental recapitulation by stem cell-based embryo models.
This resource enhances the ability to assess the fidelity of in vitro systems in developmental studies.
Facilitates more accurate interpretation of phenotypes and cell types derived from in vitro differentiation protocols.
