AD-SCs have a fibroblastic morphology and MSC-like immunophenotype (CD34+/CD105+/CD45−/CD31− or CD29+/CD44+/CD71+/CD90+/CD105+/STRO-1+/CD49d+/CD31−/CD34−/CD45−) and exhibit a clonal differentiation potential along all mesenchymal lineages [18]. The gene discussed is PTPRC; the disease is Alzheimer disease.
