Fig. 2: CRC-SCs recapitulate parental tumor features.

A Representative hematoxylin and eosin staining and immunohistochemical analysis of p-p38α in primary CRC, isolated CRC-SCs, and CRC-SC-derived xenografts. Scale bars, 100 µm. B Representative immunocytochemical analysis of CD44v6 (red) and p-p38α (brown) in CRC-SCs #21. White arrow-heads indicate CD44v6+/p-p38α+ CRC-SCs. Scale bar, 100 µm.
