Somatic and Stem Cell Bank to study the contribution of African ancestry to dementia: African iPSC Initiative.
Article in Alzheimer's & dementia : the journal of the Alzheimer's Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionAfrica, home to 1.4 billion people and the highest genetic diversity globally, harbors unique genetic variants crucial for understanding complex diseases like neurodegenerative disorders. However, African populations remain underrepresented in induced pluripotent stem cell (iPSC) collections, limiting the exploration of population-specific disease mechanisms and therapeutic discoveries.
methodsTo address this gap, we established an open-access African Somatic and Stem Cell Bank.
resultsIn this initial phase, we generated 10 rigorously characterized iPSC lines from fibroblasts representing five Nigerian ethnic groups and both sexes. These lines underwent extensive profiling for pluripotency, genetic stability, differentiation potential, and Alzheimer's disease and Parkinson's disease risk variants. Clustered regularly interspaced palindromic repeats (CRISPR)/CRISPR-associated protein 9 technology was used to introduce frontotemporal dementia-associated MAPT mutations (P301L and R406W). DISCUSSION: This collection offers a renewable, genetically diverse resource to investigate disease pathogenicity in African populations, facilitating breakthroughs in neurodegenerative research, drug discovery, and regenerative medicine. HIGHLIGHTS: We established an open-access African Somatic and Stem Cell Bank. 10 induced pluripotent stem cell lines from five Nigerian ethnic groups were rigorously characterized. Clustered regularly interspaced palindromic repeats (CRISPR)/CRISPR-associated protein 9 technology was used to introduce frontotemporal dementia-causing MAPT mutations. The African Somatic and Stem Cell Bank is a renewable, genetically diverse resource for neurodegenerative research.
