Bounded definition
The cited embryo study reports mosaic and unintended outcomes after CRISPR-Cas9 exposure of non-viable tripronuclear human zygotes. Within this page, that proposition is limited to The constructs, biological systems, protocols, assays, datasets, and comparisons reported in CRISPR/Cas9-mediated gene editing in human tripronuclear zygotes.
Definition and evidence boundary
A boundary between edits confined to treated somatic cells and edits made in embryos or reproductive-line cells that may become heritable. The bounded proposition retained by the canonical record is: The cited embryo study reports mosaic and unintended outcomes after CRISPR-Cas9 exposure of non-viable tripronuclear human zygotes.
The applicable scope is The constructs, biological systems, protocols, assays, datasets, and comparisons reported in CRISPR/Cas9-mediated gene editing in human tripronuclear zygotes. This definition must not be generalized beyond the cited source and exact record boundary.
Claims: urn:maha:claim:somatic-versus-germline-editing
Mechanism and technical context
The study reports CRISPR-Cas9 editing outcomes, mosaicism, and unintended events in non-viable tripronuclear human zygotes under the stated protocol. This is the source-bound technical context for the record; no uncited mechanism is added by the compiler.
The experiment does not establish safe or acceptable reproductive use; germline questions require distinct ethical, legal, clinical, and multigenerational evidence. The mechanism or method is therefore presented as one component of a larger system, not as evidence for every downstream outcome.
Claims: urn:maha:claim:somatic-versus-germline-editing
How to interpret the evidence
There is no universal effect estimate for this method; numerical results remain attached to the source experiment, biological system, assay, and analysis choices. The evidence maturity recorded here is single study, and the claim kind is empirical claim.
This candidate records one bounded source package. Independent replications and contradictory results must be compiled separately before evidence maturity is upgraded. The experiment does not establish reproductive safety, heritable clinical benefit, ethical acceptability, or authorization for germline use. These qualifications travel with the claim whenever it is reused.

What the source supports and what remains unknown
The inspected source supports exactly this: The study reports CRISPR-Cas9 editing outcomes, mosaicism, and unintended events in non-viable tripronuclear human zygotes under the stated protocol. It was read at Abstract; Results; Tables 1–2; Methods; ethical statement.
What remains unknown is everything outside that locator. The experiment does not establish safe or acceptable reproductive use; germline questions require distinct ethical, legal, clinical, and multigenerational evidence. No quantity, comparison, or downstream outcome is established here unless a separately scoped record measures it.

Source identity, locator, and reuse boundary
The bound source is “CRISPR/Cas9-mediated gene editing in human tripronuclear zygotes” by Puping Liang, Yanwen Xu, Xiya Zhang, Chenhui Ding, et al., published by Protein & Cell on 2015-04-18; its declared stable identity is doi:10.1007/s13238-015-0153-5.
The inspected-content locator is Abstract; Results; Tables 1–2; Methods; ethical statement. Reuse is limited to citation-with-paraphrase. Maha paraphrases the source-level result and links to the version of record; no article passage is reproduced. This metadata establishes source identity and inspection scope, not the truth of claims outside the cited locator.

Comparison and calculation boundary
Applicability is decided explicitly, not filled with generic material.
This record carries 1 source-bound proposition and therefore has no second supported side. A comparison would have to be manufactured from an adjacent title rather than from a second inspected claim, which the gate forbids.
The canonical claim declares no reproducible numerical inputs, equation, units, or uncertainty propagation; recorded uncertainty kind is qualitative. Supplying sample values would invent an unsupported quantitative result.
Limitations and prohibited inference
The claim stops where its evidence stops.
- record boundary
The experiment does not establish safe or acceptable reproductive use; germline questions require distinct ethical, legal, clinical, and multigenerational evidence.
- record boundary
A source-bounded mechanism, method, or measurement record does not establish manufacturing yield, economic advantage, safety, clinical benefit, or commercial readiness unless those outcomes are measured in a separately scoped record.
- prohibited inference
Do not treat the somatic versus germline genome editing record as medical advice, a treatment recommendation, or evidence of general clinical readiness.
- prohibited inference
Do not transfer a reported result across hardware, organisms, protocols, datasets, operating conditions, or outcome definitions without a declared comparison contract.
- editorial
This compilation reorganizes an existing inspected claim and its declared source; it does not add a new experiment, measurement, or independent replication.
- editorial
Internal editorial inspection is not external peer review, and no result on this page has been independently reproduced.

Ex-vivo genome-editing workflow
Declared strategic-dependency edge from this record. The edge is navigational and asserts no equivalence or causation beyond the cited source scope.
Selection: bridge edge
When no declared bridge edge is present, related records are linked by shared evidence or canonical domain adjacency. Those links are navigational and do not claim mathematical or physical equivalence.
Connected domain graph
Typed dependencies preserve publication state.
Only independently canonical records receive public links and relation statements. Draft graph topology remains private.
Ex-vivo genome-editing workflow
inbound connection · method
The reported ex-vivo intervention edits somatic hematopoietic cells rather than reproductive-line cells.
Ex-vivo genome-editing workflow
outbound connection · method
The cited ex-vivo hematopoietic workflow targets somatic cells and is not a germline intervention.
