KDM1A and neoplasm: Not only the number of tumour spheres formed by LSD1‐197‐211‐GFP transduced hBTICs was less than GFP transduced hBTICs, but also the average size of tumour spheres formed by LSD1‐197‐211‐GFP transduced hBTICs was smaller than tumour spheres formed by GFP transduced hBTICs (Figure S7B,C).
