INTRODUCTION
Africa, 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.
METHODS
To address this gap, we established an open-access African Somatic and Stem Cell Bank.
RESULTS
In 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. CRISPR/Cas9 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.
