FIGURE 4.
SQSTM1 protein expression was not observed in patient‐derived UDCs. Immunoblotting of SQSTM1 and GAPDH proteins extracted during third passage. Anti‐GAPDH antibody was used as a loading control. SQSTM1, sequestosome‐1; GAPDH, glyceraldehyde‐3‐phosphate dehydrogenase; UDCs, urine‐derived cells.
