This study defines the developmental potency of stem cells, focusing on pluripotent stem cells that can generate all cell types. It proposes methods to evaluate stem cell identity and provenance using molecular and functional hallmarks.
Area of Science:
- Cell Biology
- Developmental Biology
- Genomics
Background:
- Stem cells possess self-renewal and differentiation capabilities, varying in developmental potency.
- Pluripotent stem cells generate all organismal cell types, unlike lineage-specific multipotent or unipotent stem cells.
- Evaluating stem cell potency requires functional assays and analysis of transcriptional, epigenetic, and metabolic states.
Purpose of the Study:
- To define functional and molecular hallmarks of pluripotent stem cells.
- To propose a checklist for evaluating stem cell potency.
- To demonstrate the use of forensic genomics in validating stem cell provenance.
Main Methods:
- Functional assays to assess stem cell capabilities.
- Analysis of transcriptional, epigenetic, and metabolic profiles.
- Application of forensic genomics techniques.
Main Results:
- Identification of key molecular and functional characteristics distinguishing pluripotent stem cells.
- Development of a comprehensive checklist for stem cell evaluation.
- Validation of stem cell origin using forensic genomics.
Conclusions:
- Pluripotent stem cells have distinct molecular and functional signatures.
- A standardized checklist can aid in accurate stem cell identification.
- Forensic genomics offers a robust method for verifying stem cell provenance.

Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...
