Analysis of dark dots on hiPSC-derived cartilaginous particles. Histological analysis of a hiPSC-derived cartilaginous particle with dark dots at 12 weeks. a Sections were bleached and counterstained with kernechtrot. b Sections were initially bleached weakly and subjected to PAS staining, Giemsa staining, and Schmorl’s reaction. Bars, 50 μm. Boxed regions are magnified in the images below.
