UCI Review of Stem Cell Research
All research or clinical investigations that involve the use of pluripotent human stem cells shall be reviewed and approved by the UCI Human Stem Cell Research Oversight Committee (hSCRO) before such activities are initiated by or for UCI.
The following definitions of human pluripotent stem cell shall apply:
- A cell that is capable of: (1) sustained propagation in culture; and (2) self-renewal to produce daughter cells with equivalent developmental potential. This definition includes both embryonic and non-embryonic human stem cell lines regardless of the tissue of origin (CIRM Regulations § 100020).
- Per CDPH Guidelines for Human Stem Cell Research, "Pluripotent" means capable of differentiation into mesoderm, ectoderm, and endoderm.

Activities that require UCI hSCRO review:
All research or clinical investigations that involve the following activities:
- Generation of new lines of human pluripotent stem cells from whatever source and by whatever means.
- Use of human gametes
- human embryos.
- human pluripotent stem cells (iPSC).
- human fetal tissue and/ or human fetal stem cells.
- human embryonic stem cells.
- Transplantation of stem cells into humans (not including Mesenchymal or Hematopoietic stem cells).
- Activities involving the introduction of human adult pluripotent, human fetal tissue, human fetal stem cells, human embryonic stem cells, or their neural derivatives into nonhuman animals at any stage of embryonic, fetal, or postnatal development.
- Activities in which the identity of the donors of blastocysts, gametes, or somatic cells from which human stem cells were derived is readily ascertainable or might become known to the investigator.
hSCRO review is NOT required for the following:
- Adult tissue-derived multipotent or unipotent stem cells
- Mesenchymal cells (e.g., isolated from bone marrow, peripheral blood etc.)
- Hematopoietic stem cells (HSC's)
- Adult stem cells (for example cardiac stem cells)
- Cord blood cells
- Non-UCI collaborator/site/ Sponsor will create pluripotent stem cells from biospecimens collected at UCI. For example, skin biopsy samples are collected at UCI and sent to a non-UCI sponsor to genetically manipulate to obtain induced pluripotent stem cells.
- In vitro generation or use of human iPSC derivatives, that is, differentiation of human iPSCs already approved on an existing hSCRO protocol in the PI’s laboratory into a new multipotent or unipotent cell lineage, unless they meet one of the other requirements above (e.g., in vivo transplantation of neural stem/progenitor cells of any origin).
- Components of stem cells that are not viable and cannot be expanded (i.e., RNA / protein samples) received from a collaborator / company and NOT derived from stem cells grown in your laboratory.
Additional Ancillary Committee requirements:
Activities that are reviewed and approved by the UCI hSCRO may require additional review by the UCI IRB, IACUC, IBC and/or COIOC committees. The review of other regulatory committees will be in parallel with the hSCRO review.
All human pluripotent cells or fetal tissue used or derived must meet the definition of “acceptable research materials” as defined in the Acceptable Research Materials checklist.
Derivation of fetal-tissue origin cells of any kind will require, at a minimum, a non-human subjects determination from the IRB.
Once this research study has received hSCRO approval, any subsequent changes to the research plan, research team or research materials (such as source material or cell lines) will be submitted for review and approval by hSCRO. Exception: updates can be made at the time of continuing review when generation of new cell lines is ongoing from previously verified material if collected under an active UCI IRB-approved protocol
If source materials such as skin biopsies, blood, fibroblast cell lines or any other applicable materials are procured with the intent of creating induced pluripotent cell lines, an amendment must be submitted for hSCRO review and approval PRIOR to generating the iPSCs to ensure the provenance can be verified prior to making the significant efforts to generate iPSCs.
For NIH supported research that includes human fetal tissue obtained from elective abortions collected after June 5th, 2019 from elective abortions, the definition of fetal tissue includes human extra-embryonic cells and tissue, such as umbilical cord tissue, cord blood, placenta, amniotic fluid, and chorionic villi.
Note: if isolated postnatally (following birth), ‘human extra-embryonic cells and tissue, such as umbilical cord tissue, cord blood, placenta, amniotic fluid, and chorionic villi’ are NOT considered FETAL tissue per NIH definition mentioned above.
Investigators should be aware of specific NIH requirements – please visit Use of Human Fetal Tissue in Research.
UCI hSCRO Administrative review of these requirements will be provided to investigators upon request (submit your inquiry to hSCRO@uci.edu) to assist in meeting these requirements.

Activities that are not permitted**
The following (non-exhaustive) list of activities will not be approved by the UCI hSCRO:
- The culture in vitro of any intact human embryo, regardless of derivation method, after the appearance of the primitive streak or after 12 days whichever is earlier. The 12-day prohibition does not count any time during which the blastocysts and/or cells have been stored frozen.
- The introduction of human embryonic stem cells (hESCs) into nonhuman primate blastocysts and/or the introduction of any hESCs into human blastocysts.
- The breeding of an animal into which hESCs have been introduced at any stage of development.
- Introduction of hESCs into a human uterus or equivalent, or any experiments attempting human reproductive cloning.
