1 × 107 STAP cells were seeded onto a sheet composed of a non-woven mesh of polyglycolic acid fibres (3 × 3 × 1 mm; 200 μm in pore diameter), cultured for 24 h in DMEM + 10% FBS, and implanted subcutaneously into the dorsal flanks of 4-week-old mice. In this experiment, to better support tumour formation from slow growing STAP cells by keeping cells in a locally dense manner, we implanted STAP cells with artificial scaffold made of polyglycolic acid fibres. Given the artificial nature of the material, we used NOD/SCID mice as hosts, to avoid possible enhancement of post-graft inflammation caused by this scaffold even in syngenic mice. STAP stem cells were dissociated into single cells and cell suspension containing 1 × 107 cells was injected into the testis. Six weeks later, the implants were analysed using histochemical techniques.
