Generation of an induced pluripotent stem cell line from a healthy adult indigenous Nigerian participant

Genetic backgrounds contribute to cellular phenotypes, drug responsiveness, and health outcomes. However, the majority of human induced pluripotent stem cell (iPSC) lines are derived from individuals of European descent. Thus, there is a major, unmet need in the generation, characterisation, and distribution of iPSCs from diverse ancestries. To begin to address this need, we have generated iPSCs from dermal fibroblasts isolated from a healthy 60-year-old indigenous Nigerian male belonging to the Babur ethnic group. The iPSCs were generated using Sendai virus, and copy number variation (CNV) analysis revealed no new major abnormalities compared to the parental fibroblasts. The iPSCs have been characterised for pluripotency markers and morphology and successfully differentiated into neural progenitor cells and astrocytes. This iPSC line could serve as a healthy control in comparative studies and can be used in disease modelling, toxicity assessments, genetic analyses, and drug discovery processes within an African genetic background. To bolster the inclusion of African models in biomedical research, this iPSC line will be made available to the broader scientific community. Ongoing efforts focus on generating more lines from diverse indigenous populations towards creating a dedicated open-access African iPSC biobank.
